My car recently started over heating so I replaced the thermostat yesterday and drove it around. It was fine till today it started over heating again but once I stepped on the gas all the way and let of it would go back to normal temp. I looked under the hood and found radiator fluid splattered on the hood and battery but can find no leaks. What could be the problem?

Thanks Collin I looked at the link and it sounds exactly like the problem I'm having

Fluid was forced out of the overflow bottle.

Needs a head gasket job.

i thought we were going to a set a new record for overheating/head gasket threads,

its been how long now?.....a whole week since one has been started?

Are you sure that your radiator is still okay? I had some major overheating issues too and ended up with radiator fluid all over the engine. See this:

The initial cause ended up being a busted radiator. While the car was at idle, everything seemed just fine. I thought the radiator was okay. After continually losing fluid, I figured I was missing something. So, I pressure tested the cooling system and it was leaking like crazy. The leak was at the seam of the plastic and metal, so it was very difficult to see. I would hate for you to replace the head gasket only to overheat again and end up having to replace it again.

To pressure test the system, I did the loaner tool program from Advance Auto. You can buy the Powerbuilt Tools Cooling System Pressure Kit (22 Piece) #940427 and then return it for a full refund when you are done.

I am not sure if others agree with taking this step. But, it is free and it takes all of about 15 minutes to do. So, I figure it cannot hurt.

Okay guys here's a new update it turned out to be just the hose clamps that needed to be replaced. I since then replaced them all and it hasn't over heated since. I guess I got lucky?

So there WAS a leak?


Drive it several hundred miles and keep an eye on what the fluid level in the plastic reservoir does, before you say it's all good!

UPDATE: it no longer over heats I had to replace the cooling fan sensor but now I have a different problem. When the car is in park it idles rough I took it to get checked but no codes came up for misfiring. I replaced all spark plugs and that didn't seem to help. What else can I try to resolve this problem?

ezone

What are you calling rough?
Lopes? Misses? Vibrates? Noises?

What did the mechanic say about the "idles rough"?

What codes does it have?

05civichonda

Has no codes at all and the car vibrates roughly.

ezone

What did the mechanic say about it? He's the one who had the opportunity to experience the problem in person.



I can only guess at things from my recliner. Motor mount(s)?
