How do I stop my car from overheating?

I have no leaks or drips anywhere I can see.

Hi,

I watched the video. Does this happen when the engine is off? If you turn the key on when the engine is cold, does it do the same thing? If so, it sounds like an issue within the coolant temperature sensor.

Does the coolant ever boil over? Has the vehicle been checked for cylinder head gasket issues? Does this happen if you are driving at highway speeds or just driving in town? Have you confirmed the cooling fan is turning on?

Let me know. Also, take a look through this link that explains what to look for with a bad head gasket:

Let me know.

Take care,

I haven’t turned it on since making the first video last night and here is what it does: Once I turn the car off, I can hear the coolant bubbling, but nothing ever spills out or overflows. I don’t believe it’s been checked for gasket issues but looking at the link I don’t have any of those issues. It gets hotter faster when I’m on the highway but driving through town it slowly creeps up. And the cooling fan doesn’t come on when first starting or after running it for a couple of minutes, but they do come on when I turn the A/C on.

I want you to try something. When the engine is cold, remove the radiator cap and start the engine. Let me know if coolant comes out when it is running and still cool.

If it doesn't, allow it to run for a bit. Check to see if there are air bubbles in the coolant.

Let me know what you find.

Yeah, coolant out with the cap off.

Hi,

If that happened cold and it shot out, we likely have a head gasket issue. If the coolant stops coming out, allow it to run and see if there are any bubbles in the coolant before it gets too hot. See pic below

Okay, but does it matter if it looks like the picture? Because my just spilled out as if was overfilling, not necessarily bubbles.

Hi,

If there is a leak, usually it will look like the pic. When you started it, how quickly and aggressively did it come out? I have actually seen the shoot out like a fountain. LOL

Let me know. Also, you may need to perform a test to determine if there are exhaust gases in the coolant. This is really easy to do, and the product can be found in nearly any parts store. If you look at the link, I attached above related to a faulty head gasket, drop down to test 4, chemical test.

Let me know.

it started coming up around the 7-minute mark. And it wasn’t some big explosion, just overflowing but I’ll look into the test,

Hi,

Okay, that may not be the issue, but I would still check it and test for exhaust gases in the coolant.

Let me know what you find or if you have other questions.

Take care,
