Checking a car's radiator involves taking off the cap after checking for heat or pressure, and looking for green liquid to be close to the top. Learn about serious problems that can result from a car overheating with help from an ASE-certified technician in this free video on radiators.
Hello, my name is Chuck Orlandi with Miami Shores Auto Repair, here in Miami Shores, Florida. OK, in this clip we're going to talk about how to check a radiator, the water level in your radiator, antifreeze level, what ever you want to call it. OK, this is a Dodge pick up truck. This one has an external tank, some cars have a cap right on top of the radiator, and a lot of them have an external tank now-a-days. What you want to make sure of here is that the car is not hot. When they're hot, they build up a lot of pressure in the hoses, and you can always tell when you squeeze them, make sure that there's no pressure before you take the cap off. It's dangerous. So when people come in here, and the, and the car's hot, I make sure that I let it cool off first. What you do here, it's a two part process, you turn it, it'll stop, push it down, turn it again, and remove it. Look inside, we've got no problem here, it's almost to the top. It's green, which means it's got antifreeze in it. You can also test it with, there's a item that you can test the level of the antifreeze to make sure there's enough of the freeze point, but here in Florida, we don't really worry about that too much, but up north, if you're in the freezing temperatures, you're going to have to, you know, check that to make sure you've got enough antifreeze in there. Again, the importance for checking this is one of the more serious problems you can have with a car engine is over heating it, and you don't want that to happen. That can cause, you know, major, major expense, major issues. So, again, this has been Chuck Orlandi at Miami Shores Auto Repair.
