- Sure we've done some sweet
cooling system upgrades but there's a whole nother
fluid in your engine that can overheat. And that's your engine oil. So if you're driving hard,
you're driving on the track, you're living in the desert or you're turbocharging your Miata, your engine oil can get
too hot to do its job and yeah all the fluids
in your car matter. But your engine oil is at the top of the totem in terms of importance, but how do you even stop your
engine oil from overheating? And how do you even know when you need to? Well, today we're going to
answer those questions and more because we're gonna preemptively install this sweet little oil cooler
under this stupid little Miata. Now, if it seems like
I'm just filibustering on the whole turbo install,
well, it's kind of cause I am much like you
guys, I'm at the mercy of Auto Parts suppliers
and parts aren't in stock. So I'll turbo as soon as I can. Until then we're gonna do some
upgrades like oil coolers. I'm Zack and this is Money Pit. Let's be cool again, no I don't work. (playful music) Alright and before we get into it, let's get a grip on
what we're really doing. Now engine oil, like
most fluids gets thinner as it heats up. So to demonstrate that I've got a very scientific
experiment lined up, I've got this Valvoline VR 120 50. This is what I run in the RB. And I had this in the freezer. So it's pretty cold. We're gonna put it in this little dropper and see how quickly it passes
through that little tiny hole. And we're gonna do the same thing with the same oil at a
much higher temperature. All right, it's not that cold 60 degrees, it's been in the freezer
for like 20 minutes. But it's cold enough that you
can see how slowly it flows. So let's see at what rate
it comes out this tip. And now this is some thick
engine oil, this is 2050. So it might take a while and
I'm not putting any pressure. I'm not squeezing it. Just letting it drip out how
it wants to drip really slow, aah really slow. - [Eddie] Now we're gonna wait for it all to come out right? - Yeah that's the only way to know. So we'll time the entire amount
and then we can do it again. Right? That's the only way
to make this scientific. All right now let's stick this in the sun for like 20 minutes and see how it acts after a warms up. Science. (upbeat music) You know what I hope we don't
have an oil crisis today. - [Eddie] Nice plug man. - Thanks man. All right, so the sun has got our oil up to a
whopping 130 degrees Fahrenheit. So we're only about double
in terms of temperature. I think it was 60 degrees before. So 70 degrees more and
you can already see just how much more thin it is. It just is so much more runny and flows so much better or
resists flow so much less. And you can see, I mean, clearly that's just coming
right out of the tip, hardly any resistance. So you can imagine that as you continue to get a hotter it
continues to get thinner. And that's good to a point
there's an operating temperature at which your engine oil should run and you really want it
to run colder than that. You don't want your engine
oil to be as thick as it was when we started this. That's why you shouldn't beat on your car until your engine oil
is up to temperature. Well, at least above like
150 degrees Fahrenheit. (upbeat music) So how do you know when
you need an oil cooler? What is too hot? Just so you got to look at your situation. I live in Southern
California where it is hot. It's basically the desert. I am taking the car to track days. I like to beat on it in the canyons and we're gonna stick
a turbocharger on it, which is gonna add a lot of heat. So for me, an oil cooler
obviously makes sense. Things are hot and I'm not helping. But if for you it really depends
on what you got going on, what you got going on in your engine bay, where you live and how you drive. So if your situation
checks all these boxes, yeah it probably makes sense. But if you're looking
more like these boxes, probably not so much. Okay so now that we know
what we're up against and we know that we want an
oil cooler, what do we do? (upbeat music) Well, the boys over at
Flyin' Miata sent us their oil cooler kit for the
Miata and boy it's sweet. It comes with a nice set trap oil cooler. It's basically just a
radiator for your oil. The oil goes through this air
can flow through these fins and remove heat from your oil. It's really simple. So to get the oil to the cooler, you have to install this sandwich plate. Basically it sandwiches
where your filter goes and oil will come out and back in these two
holes, it's pretty smart. It's got a thermostat so that
you're not cooling your oil while it's still too cold. So honestly this should be
a pretty easy installed, which I am excited about. Especially after all those dashboards. (upbeat music) All right we got the car in the garage. Now I'm gonna lift it up
because well our oil filter and basically everything
we're gonna be working on, is under our new intake manifold. So we're gonna be working from underneath pretty
much entirely today. (upbeat music)
(Jack tool squeaking) (clattering) It ain't going nowhere. (tool scrapping) Hey I found a nut. (upbeat music) Kinda looks important. Well, we'll just put that there for now. Alright so the first thing
I'm gonna do to get ready to install this thing is put these fitting adapters
into our actual oil cooler, Flyin' Miata includes these and they basically go
from the O ring fitting that the cooler has to an
AN fitting for the lines that we're using. And luckily, our little experiment, afforded me a nice little oil dispenser when you're putting these kinds of aluminum fittings
together ORF fittings, anything of this sort, just
a little bit of engine oil or assembly lube will make
sure you don't mess up threads. So these are aluminum fittings
that we're gonna be using. And any time you're really
working with any AN fittings, they're usually gonna
be made out of aluminum and aluminum while it's lightweight and good at transferring heat
and doing a lot of stuff, it's kind of soft and it's easy to damage. So when you tighten
these kinds of fittings, you can do a few things. You can get specific arm wrenches that are made out of aluminum. They're anodized so they're not any harder than the fittings that
you're trying to tighten. So these do a pretty good job
of not damaging your fittings. You can also just use an
old school Crescent wrench with a little bit of masking tape on it to try to protect the finish. And it's really it's not
that big of a deal if you had damaged the finish a little bit but I mean, these are nice new fittings. You want it to look nice right? So a little masking
tape can go a long way. (upbeat music) All right so we've got our
fittings in our cooler. So this thing's pretty much
ready to go in the car. So I guess it's time to get under the car. I'm gonna pull off the old oil filter, probably make a little bit of a mess and then we can start installing. We can put our sandwich
plate on, put our lines on and mount our cooler. Let's do it. So this thing has a pretty
fresh oil change in it. I just changed it probably
a couple of 100 miles ago. So I'm not gonna do an oil
change while we do this. And I'm gonna try to
not lose that much oil. We'll see how it goes. So I'm gonna put a
little purple tile down. And then I'm just gonna hold this cup. Are you ready? What? - [Eddie] You're gonna hold a Dixie cup? - Yeah, hell yeah I'm
gonna hold a Dixie cup. Ah damn it. (laughing) Literally could not have been worse. (laughing) - [Eddie] Oh My God my knee. - I honestly didn't think
it was gonna go that bad. (laughs) I've done that before with success. - [Eddie] Let me see what
you caught in that Dixie cup. - Hey, there's still plenty
in the filter though, you know, we didn't lose it all. (laughs) (upbeat music) Okay. Now that we've cleaned
up our little oil crisis, we can continue. All right now we need to get our sandwich
plate ready to install. All we gotta do is install our
fitting adapters into this. A little overing Jonny here. Get a little oil on. (upbeat music) (wrench clacking)
(upbeat music) Cool. All right. Now the last thing we need to do get a little oil on
our sealing gasket here, help it seal up. (upbeat music) So we're ready to install
our sandwich plate here. And it's gonna be pretty easy. Basically this a sealing
surface goes in place of the old oil filter. So this will just go on. Then our little threaded adapter will spin onto the old oil filter threads. And then these are gonna be
our new oil filter threads. But without further ado, we're just gonna put this
on thread it into place and I'm gonna leave it a little loose so I can adjust we want to
get fitment and just right, so we're not gonna tighten it up yet. We're just gonna get her on. (upbeat music) All right so now we're ready to mount up our actual oil cooler and to do that it should be pretty easy. Flyin' Miata includes these brackets, they sandwich in on the front bolts of your power steering rack here. So we'll be able to mount
the thing right here. It's gonna look really nice. I hope we don't have any clearance issues but if we don't, it should
be pretty, pretty sweet. (upbeat music)
(clanging) Okay, that was pretty easy. Yeah, look at that,
that's that's pretty good. Oh, you know what I need to do. I also need to put oil in this thing. If I let this dry, the engine would end
up without oil pressure for just a second but
a second is too long. Now this does use a thermostat right? So that it's only working
when the oil is up to 10, but it works on the far end of the system if that makes sense. So if it needs to fill this whole thing from empty before, oil pressure gets to
the rest of the engine. The engine will be without oil
pressure just for a second. And that's too long. So we're gonna fill this thing
most of the way with oil, not brimming cause well you saw what kind of mess I can make. - [Eddie] All right she's still. Let's see if he can keep
all that oil in there. (soft music)
(laughing) - I'll sacrifice my body if, if not, not - [Eddie] The precious carpet. - Yeah that's right. (gentle upbeat music) - [Eddie] Yeah that's good. - It good. Alright so now we've
got our cooler mounted. We've got our sandwich
plate loosely in place. Now we're going to fish
our lines into place, get everything sorted out,
get it all fitted just right. So that the lines are rubbing on anything. And everything's nice and happy. Then we can tighten
down the sandwich plate, tighten our lines up, put our
filter back on and that's it. (electronic music) All right so the lines are
attached to the sandwich plate. They're attached to the oil cooler and they are run in a way
that makes me feel warm and fuzzy inside. So I'm gonna put some
zip ties on them just to make sure they stay
where I've got them. Tighten up the sandwich plate
and baby we're home free. This thing looks awesome. (electronic music) Everywhere you look. There's something cool going on. - [Eddie] there's money. (laughing) (electronic music) - Alright so before we get
this thing back on the ground, we're gonna fire it up so I can easily take a
look from underneath. Make sure there are no leaks. And then we'll put it on the
ground top off the oil level. And that's it. What a smooth day. (upbeat music)
(engines roaring) Any leaks? - [Eddie] Eeh (upbeat music) - Is that a no. - [Eddie] Yes you got it right. - Nice nice nice. You got me a little bit.
- Did I? Am not gonna lie. He had me in the first
half, but the second half. It's all mine looks like this
thing's dry, which is sweet. Now granted, I'm gonna want
to check again after driving for a while once the oil thermostat opens and it's really flowing,
like, like it should but it's nice to know that
things are dry for now. So I'm gonna get off of Jack stands and get the oil level topped off. Make sure we're all good. And that's it. And we're still right up on there. We're doing it. Man, wow, would you look at us? What a day it's been? That's a pretty good mod. That's a solid mod in my opinion. Well thought out high quality and there was no drama installing it. Ah damn it (laughs) So this has just been one of those things where we're future proofing the car for what we're gonna do. And that's really the way
you should modify a car. You should kind of do these
things before you need them. If you do an oil cooler after
you're overheating your oil, it might be too late. So thank you guys so much for watching. I hope you had a fun
time watching the video. We had a good time making it. As always don't forget to
subscribe to the channel. It helps us out a lot and don't forget to follow me on Instagram @ZACHJOBE and follow donut @DONUTMEDIA. I'll see you guys next week. - [Eddie] Still not gonna be a turbo.
