How to Tell if Your Head Gasket is Blown

1, 2, 3, 4! Rev up your engines! It's time for scottykilmer.com. If your vehicle isn't running right, your engine might have a blown head gasket. But how do you know if your head gasket is really blown? Now, the head gasket fits between the head and the block of the engine. So you can't see if it's leaking because it's inside the engine. So you need one of these combustion leak tester kits. And you perform a little chemical experiment to tell you if the head gasket is blown or not. It's a pretty simple test. Inside, there's a test tube and some test liquid. And the first thing you do is take off the radiator cap from the radiator, and then get a turkey baster, like this, and suck some of the coolant out so there's more space inside. You suck some of the coolant out, because you don't want coolant being sucked into the tester. It'll give you a false result. Then you take the bottom half of the tester and stick it in the radiator, and then pour some of the test fluid up to the line, right there. Then put the middle of the test tube on top of it, and pour fluid to the second line, right there. Then put the top of the tester back on, then start the engine up. Then queeze the bulb a few times. That sucks air in. You can see the air being sucked in. This liquid is checking for combustion gas getting into the cooling system. If they are, there's a problem in the head gasket. And here's how you tell. If the blue liquid turns yellow, like this, it mean your head gasket's blown. Since the blue test liquid has turned yellow, that means that there's combustion gas inside the radiator. There's a crack somewhere inside the head gasket or the engine. So as you've just seen, it's a very simple test with this kit to find out if the head gasket is blown. You certainly don't want to take a whole engine apart just guessing. Now you know one way or the other. And remember, if you've got any car questions, just visit scottkilmer.com, and I'll answer them.
