Subaru DOHC Timing Belt Kit | STEP-BY-STEP Guide

what's up guys and welcome back to my little super only shop here in Northern California in today's video I'm gonna walk you guys through a really critical maintenance procedure for any Subaru I'm gonna walk you guys through installing a timing belt in a time del accessory pulleys on this ej 205 motor this ej 205 motor is a dual overhead cam turbo motor from a 2005 WRX which i'm installing in my 1998 World Rally Blue Impreza RS coupe thanks so much for checking out the video guys I really appreciate it my name's Luke this is a super only show [Music] this is my little super only shop it's a DIY Subaru channel a channel where all I do is Subaru build and race new boom vehicles and more sport events it's a DIY themed channel where I walk you guys through the steps to get your soui back on the road and hopefully do a little racing of your own so thanks for checking out the video guys I really appreciate it now the reason they're replacing your timing belt in time about pulleys is such a critical maintenance procedure is because if you don't replace those components about every hundred thousand miles like the manufacturer recommends those pulleys that timing belt could fail if you have a failure with your pulleys or your timing belt on Subaru engine those valves will actually make contact with the Pistons and when they make contact with the Pistons they're definitely gonna get damaged they're getting it bent and they might even damage a piston and the cylinder walls as well which means if any of the components in your timing belt system fails you're probably gonna have to have a total engine rebuild so I'm going to walk you guys through the installation of this time belt kit on this ej 205 engine which i mentioned earlier is a dual overhead cam turbo motor okay guys the very first step you're going to think about anytime you do anything associated your timing belt is you want to rotate that crankshaft and those Pistons to the correct position inside that piston bore so that those Pistons can't make contact lay the valves in your cylinder head in the way that you do that is you go ahead and rotate that crankshaft and that main crank bolt right here on your crank here you're going to go ahead and rotate this crankshaft until this little hash mark on the back of that crank pulley is straight up in the vertical position it's aligned with this little hash mark above it on the block someone go ahead and do that right now go ahead and grab a ratchet and a 22 millimeter socket and rotate that crank bolt just like that so that little hash mark is lined little hash mark right above it on the engine and what you're actually doing when you rotate the crankshaft to that position is you actually rotate the Pistons so that during the midpoint of their bore that way the tops of those Pistons can't make contact any of the valves in your cylinder head and the reason you need to be aware of that is because when we install this time belt and all these timing components on this dual overhead cam motor we're actually have to set the timing belt with some of the valves open on the cylinder head to get everything aligned in the correct position and that's why you want to make sure those Pistons are in the center of the bores and they're not atop the bore they can actually make contact within those valves okay guys first step to this DIY I'm gonna walk you through where all the marks on these cam gears are for and how we use them to align these cam gears with marks on the outside the time belt cover before you install your timing belt okay guys we're on the right side of the engine and on the right side of the engine you actually don't have to use any specialty tools to hold these camshafts in the correct position to get them lined up with all the marks so it's a really good side to walk you guys through all the marks and how we want to align all these marks on the outside of the timing belt covers here's that single hash mark on the cam gear and you want to line this hash mark with a single little slot in the back of your timing belt cover okay guys I've moved the camera down just a couple of inches and you're still looking on the right side of the engine and what we're looking at is a double hash mark right here on our intake cam gear and a double hash mark right here on our exhaust cam gear and when the double hash marks on your intake cam gear and on your exhaust cam gear are lined both these cam gears should be faced correctly and you should be ready to install that timing belt but there's actually one more place that you want to make sure that's lined up correctly and that's down here on the side of your timing belt cover and the last spot to align is right here this is a little hash mark on the exhaust cam gear it's in about the nine o'clock position and you align this hash mark with this slit right here that's on the outside of that plastic time back cover you we just walk through how to line up all the hash marks on the cam gears on the right side of the engine but on the left side of the engine it's actually a completely different story which is why on the left side the engine you actually have to use a specialty tool to get these camshafts aligned in the correct position before we install that timing belt but we're still going to use the same logic for lining up those marks we're going to line up the single hash mark to the straight-up vertical position with the back of that time belt cover and we're gonna use those double hash marks to line up our intake cam gears with our exhaust cam gears and then last we'll also use that single hash mark to line up the bottom exhaust cam gear with that little hash mark on the side of our timing belt cover okay guys what you're looking at is actually the specialty tool that you use to rotate those cam gears into the correct position so that you can install that timing belt and when you use one of these specialty tools it basically makes installing these timing belts a hassle-free process now there's actually several manufacturers on the market that are making these specialty tools company 23 is one of the more popular ones but there's also several other manufacturers out there that are selling this specialty tool on Amazon and I've actually got one of the generic brands right here in front of me this generic one is actually sold on Amazon and actually have it on my super only store which you can find at the link in the description this generic version will run you about $30 whereas the company 23:1 I think will run you about 50 or 55 dollars and actually include both of them my Amazon store so you can go ahead and click the link and you can read up on either them and you can go ahead and pick one up for yourself if you need to do time belt anytime in the near future basically the way these suckers work is that this sucker will actually slide into the bolt that holds that cam gear in place we'll go ahead and walk through this process right now on the engine so basically the tip of this little fitting fits into the head of that Allen bolt and the higher quality ones like this one will actually have a little magnetic insert in the tip which will help hold this fitting in the bolt when you're going to the installation process so if you guys are gonna buy one of the generic brands make sure it's got these little magnets inserted in the tips so we'll go ahead and put that in the head of that bolt like that and then you go ahead and grab a 19 millimeter wrench put that over the end of the fitting and then you can rotate that cam gear into its position to line up that single hash mark at the top with a hash mark in the back of that plastic timing gear cover and they'll go ahead and install that second fitting in the lower exhaust cam gear and then rotate this lower exhaust cam gear so that these two hash marks on the exhaust cam gear lined up with the two hash marks on the intake cam gear directly above it and incidentally when you rotate this exhaust cam gear you want to rotate it counterclockwise like this to line it up with those double hash marks just like that and as you can see now both those hash marks are perfectly lined up and then you go ahead and grab that steel plate and you bolt the steel plate to both those fittings that way the intake cam gear and the exhaust cam gear are locked in place together and make sure you don't forget to use those locking washers and when both these bolts are locked in place it actually locks these cam gears in place that way they can't slip out of position when you're installing that timing belt so go ahead and snug those bolts down now and lock everything in place that way nothing pops free always start installing that timing belt [Music] [Music] okay now that we have the cam gears locked in the correct place on the left side we can go ahead and install the first couple of pulleys and start installing our timing belt okay guys now that we have our crank shop and our Pistons set in the correct position and we have these cam gears locked in the correct position that way nothing's gonna make contact while we install this time belt we can go ahead and move on to the next step which is installing the first couple of pulleys for this time belt okay guys the first pulley we're gonna install is one of the upper pulleys it's a double bearing pulley and it's one of those smooth pulleys and you bolt the sucker in right here so grab yourself some Loctite and use just one or two drops on that bolt thread just like that and we'll go ahead install that pulley and torque it down to 28.9 foot-pounds that's the factory spec that Subaru gives I really got to stop and say any time you guys gonna work on a Subaru engine there's really only a few critical metric sizes you need to have in your toolbox and having these nut drivers is really a huge help and a huge time saver so get yourself a good set nut drivers and really the only sizes you need are eight millimeters ten millimeters 12 millimeters and 14 millimeters so get yourself a good set nut drivers I don't know if you guys notice in my videos by using these whee-ha brand nut drivers I've actually had them for over a decade they work great and actually have them listed on my Amazon store I believe they sell them as a set or you can buy them individually and they're really good addition to anybody's tool set to work on your Subarus alright 28.9 foot-pounds now the next thing you want to install is your hydraulic tensioner and I've actually already installed my hydraulic tensioner but the torque that you apply to the bolts to both in your hydraulic tensioner are actually the same cord that we used for this bolt 28.9 foot-pounds and if you guys are using a new hydraulic tensioner you bought the shelf definitely consider reading the instructions and bleeding it because sometimes there can be a little air bubble craft net hydraulic tensioner and it won't actually apply the correct pressure to your belt I'm actually not replacing my hydraulic tensioner because this one was actually replaced recently okay in the last upper pulley is this little idler pulley put a little lock tight on that guy - just one or two drops will do and then go ahead and torque that guy down to twenty eight point nine foot-pounds as well and in case you guys are wondering you're gonna leave that pin in until everything's installed we've double-checked that everything's aligned correctly and then for the final step of this installation you actually pull this pin and you let that piston in that hydraulic tensioner expand and put tension on that timing belt but the whole point of having that pin is it holds that hydraulic tensioner in the closed position that way you're not applying any tension on your time belt you can install it or remove it as needed so definitely leave that pin in for now okay guys the next step is actually to grab that time belt and we're gonna start installing this time though when you take a closer look at it you're gonna notice there's actually several markings on the top of that timing belt they're gonna give you an idea of how you should align it when you first install it one of the first things you'll notice is there's actually a bunch of these little dots to form a line at some point in Italian belt these little dots are the mark on this time belt that you use to line up with a mark on that crankshaft gear and that's where I like to start lining up this line with the marks on that crankshaft gear and then as you move down the belt you actually see it through several other lines they're solid lines these lines actually line up with the hash marks on your cam gears on your left side and on your right side so let's go ahead and weave this sucker through these gears and start getting this timing belt installed on this EJ 205 motor this is actually when having those binder clips comes in handy grab yourself a handful these binder clips and use these binder clips to hold this timing belt in place as you start wrapping around these gears and getting it aligned correctly they're a real lifesaver and they make installing these tying belts a hell of a lot easier to do as you can see I'm using to those binder clips on the intake cam on the left side of this engine and then I'll use a big binder clip right here told this time belt in position while I get those lower pulleys ready to get installed and slip over the gears of that time belt okay so at this point we're ready to install that lower cog here go ahead and grab a little bit Loctite drop a couple drops that lock tight on that bolt and install that lower cog here while you engage it with a teeth of that time belt little lock tight just one or two drops and then go ahead and thread that gear in right here and again torque that bolt down to the factory spec of twenty eight point nine foot-pounds okay I've got this lower cog here installed now as you guys can see the teeth of this tying belt are meshing with the teeth of that cog here right here the back side of the belt is what turns that water pump which is a good thing to point out basically anytime you have a smooth pulley that's gonna ride on the backside of the time belt like we have right here on the water pump and like we have right here on this upper pulley smooth-faced pulleys will always ride on the back of that tine belt so it's a good rule of thumb to remember when you're installing this tie-in belt and you're weaving it through all these cog ears and all these pulleys okay so at this point we're ready to install our last pulley it's a lower pulley and it's a smooth pulley so the backside of this belt is what's gonna be riding on that pulley at this point you should have a little bit of play in that belt and if you don't have any play there's definitely something wrong with the way you have it installed so far so go ahead and grab that last pulley grab your lock tight put a couple drops Loctite on it just one or two drops is all you really need and then for the bolt that holds this pulley in this is the one that can be a little bit tricky for some people you actually have to thread this bolt in wow that time belt starts putting a little bit of ten on this pulley I'm I walk you guys through it right now okay for this lower pulley we're gonna thread it into this hole right here on the front of the block and we're gonna do is we're gonna lift that time belt up and we're gonna get this tip of this bolt started in that thread hole and then we'll slowly rotate it horizontal as we start threading that bolt in that way we can tighten it all down I'll tell you guys right now having a nut driver for this step really makes a lot easier okay guys and that's it it's really pretty easy if you follow those steps and then you want to go ahead and torque that bolt down to the factory specs 28.9 foot-pounds okay guys with the installation of that lower pulley we're getting really close to being done with installing this time belt kit the next thing we want to do is double-checked all these marks or lined up correctly this mark right here should be lined up with a centerline of that crank gear right here and then will be moved down that belt and we'll move over to our cam gear this line right here should line up with that single hash mark right here on the cam gear and that mark right here in the back of that cam gear cover and then if you continue on that belt there's actually another mark on the side right here this mark right here should line up with that single hash mark right here on the exhaust cam gear and that little cutout right here on the back of that timing gear cover and then we'll go ahead and move over to the right side and we'll look at the intake cam on the right side here's that little mark on the top of that intake cam this line right here lines up perfectly with the hash mark and I cam here and that little cutout in the back of the timing your cover so this one's lined up perfectly and if we go ahead and move on down this line right here is lining up perfectly with a little vertical line right here in the exhaust cam here and that little cutout right here and the back of the timing gear cover so this belt is completely lined up correctly all the paint marks on the belt line up perfectly with all the hash marks on the gears and all the wedges on the back of the timing gear covers and we can go ahead and remove that specialty cam gear tool over there on the left side and we can move on to installing our timing belt guides and reinstalling our timing belt covers these timing belt guides are required for manual transmission vehicles because away the transmission engages with the engine can create a shock load to that belt which can actually knock the belt off the teeth of that crank gear and will cause a time belt to skip which could cause major damage to your engine so for those of you who have manual transmissions make sure you always install these time belt guides back on your engine and when you install these guides you actually have to install them so they have a certain clearance between the guide in that belt because if they make any contact with that belt you're obviously gonna damage that belt and eventually they're gonna cause that belt to fail in the factory recommendation for the clearance you need to have is about one millimeter or 20,000th of an inch a lot of the time when you get a time belt kit it'll come with these little specialty installation tools this little tool will actually give you the proper clearance for that time belt guide and the way it works you just set it down on your belt like this and then go ahead and set that guy down over that little tool bolt that guide down and after you bolted it down you actually pull this tool out and the gap that remains will be the proper clearance of one millimeter or 20,000th of an inch and of course on these bolts you also want to add a drop or two of that thread Locker so I'll go ahead and drop just one or two drops of this bed rocker and we'll go ahead install that bolt and then after you've tightened it down you should be able to pull that plastic tool out and you'll have your one millimeter clearance and then go ahead and torque those bolts down to about 7.1 foot-pounds that's the factory recommended torque setting and then don't forget the time belt guides there on your cam gears these ej motors use time belt guides on the cam gears as well as that crank gear torque these bolts down to about 5.1 foot-pounds just a little bit less than the previous ones and make sure this time belt guide has about one millimeter or twenty thousand seven inch clearance above that belt and again I'll just use that same plastic clearance tool that they gave me for the crank gear but I'll spread it out a little bit wider for these cam gears that way I know I've got that one millimeter clearance that you need to have and then go ahead and snug that down about 5.1 foot-pounds you definitely don't want to have any of these time belt guides rubbing on a time belt okay guys without last step we've wrapped up installation of this timing belt and all the pulleys associated this time belt and we're getting this EJ 2:05 engine really close to getting reinstalled back into my 1998 World Rally Blue Impreza are a scoop house you guys saw earlier in this video actually walk you guys through how to use a specialty cam gear tool which makes the installation of new timing belt on an EJ motor a really really easy process if you guys are interested in picking up one of those specialty cam gear tools you can actually find it on my amazon store which i'll include in a link in the description thanks again for check out the video guys I really appreciate it if you have any questions or any comments please go ahead and leave them in the

share it with them thanks a lot for checking out the video guys thanks for all your support my name is Luke this is a super only show until next time guys later [Music] thanks again for watching this video guys as you guys know I'm a die-hard Subaru enthusiast and have also had the opportunity to be involved in Motorsports for over two decades now but I'm also a professional hydrogeologist and I've actually spent years in laboratories performing experiments where I studied the flow of fluids using the properties of physics and fluid mechanics in these youtube videos I'm actually able to combine my experience from the laboratories and all the research I've done with my experience from although motorsport series I've been involved in and my passion for Subarus if you have any professional inquiries about Subaru related R&D or digital marketing in media you can contact me at Subaru only shop at gmail.com thanks for checking out the video guys I really appreciate it I hope to hear from you soon
