over heating blah, whats that problem? Options

[urbandork]

My cars temp gauge shows the engine temp to spike up and down from time to time. Its cool (pun) on the freeway as its got free flowing air and only happens sometimes on the road as well as sitting.

The fan does not go on all the time. At first i thought it might be the thermostat but at this point im not sure. Could be the fans or a plug? I know the fans work cus they do go on, when they want to that is.

at this point i just turn on the AC and thus the fan comes on cooling it off.

any ideas?

huh? ac helps cool your engine temps?

it might be the sensor that monitors when the engine fan turns on..

try hard wireing your fans to be on all the time.. and let your car idel.. If it stays cool then we can rule out a fan problem..

If it still over heats, its could be something else.
