Hey guys, let me say that I have searched and could not find the answer. I was driving a week ago and I noticed my temp gauge started to go up. So I pulled over and cooled down, and put more coolant into my radiator. Once I got home I checked my radiator to make sure I still had a proper amount and I noticed that my overflow resevoir was completely full and I was low on coolant again. So I filled my radiator back up and poured some out that was in my overflow to the correct amount. Drove it and within 2.5 hours my temp guage started rising and I was only a block away from my house so I figured to turn the heat on and once I did, my needle jumped straight to hot and I pulled over and turned my car off. Checked it and low again. I checked my hoses and none of them are leaking. Anybody suggest anything? thanks.

 

another over heating problem eh?

start by checking your oil. If its milky then you need new head gasket.If oil looks good then change your coolant and thermostat. If that doesn't work then it may be headgasket or water pump but start with the cheap stuff first.

 

My oil and headgasket are fine. I just re-checked all my hoses and none of them are leaking. Could a faulty thermostat cause this somehow?

how do you know your headgasket is fine? Did you do a compression test? Change your thermostat.

 

I havent changed my thermostat but I did get a compression test done and its good. Thanks for the responses.

A compression test wont always show a leaking head gasket esp if it is just starting to leak. You need to have the coolant tested for exhaust gasses. If they are present then you will have to change the head gasket. This is not a hard test or expensive to have done. I would do it before you just start throwing parts at it. It could very well be a thermo stat but with your description of the overheating and coolant in the overflow. I would suspect the head gasket first.

 

whenever I notice my temp guage start to rise, I turned on my heat and my guage jumped straight to hot. I dont think a blown headgasket would cause that, could it?

Why in the **** are pple talking about coolant lines?

It's the thermostat, guarantee it.

When you move coolant lines **** drops into the thermostat and jams it up. It happens every time, it's a $12 part, switch and it and enjoy a normal temperature engine.

 

its leaking somewhere! your rad cap is supposed to maintain pressure and vacuum, if your radiator was really low and you still had coolant in your reservoir that tells you that there is a leak. whether it is a headgasket or heater core. turning on the heater shouldnt affect the engine temp. it turns the blower on. sometimes an "external" headgasket failure which will send combustion pressure into the coolant system, then compresses, and shoots coolant out of the overflow reservoir. That kind of leak keeps coolant out of oil. make sure your radiator isnt cracked.

 

will do, thanks. Ill keep you posted
