Camaro over heating...

Question

Three weeks ago my car started to over heat and i checked the coolant and it was empty so i filled it. That fixed the problem but just today it started to do the same thing again. I checked the coolant and its still full?

Was is the most common thing that could be causing it. I mean it runs "cool" when driving for the most part but if i sit it goes past the middle marker and the check engine light comes on? I mean there is no smoke coming from the engine or any thing. I am not sure what is wrong?

Do you really think its going to cost me over 500 (not including mec fees)?

Where are some place's i can get cheap parts?

What are some things i can check to find out what the problem really is?

thanks for the much needed help =]

Answer 1

you can have a pressure check ran on the cooling system to find out if it has a leak in it,that will tell you why it got so low on coolant and maybe why its running a little hotter than it should run,it could possiblly be a water pump going out on it or a head gasket leaking on it,having the test done will answer a lot of questions on it,good luck.

Answer 2

If you filled it up three weeks ago then i don't think you have a leak ,not if it holding water that long. Check and make sure your fan is working and you might need to change out the thermostat,it might not be opening or closing right and allowing it to run hot.

Answer 3

Normally, a coolant/water reservoir does not go empty in a very short period of time, thus, check the source of leakage.  Call a qualified mechanic to check on the water pump, it might not be working well and may be the cause of the leak. Also include the fans, belts and radiator hoses for leaks/breakage.  If all are OK but overheating exists, check on the thermostat and/or conduct radiator overhaul.

Answer 4

Have it checked out ASAP. Cars 'need' water just like we do, they do not function without. Mine had same problem and needed a new water pump. $200 for my jeep.
