Well it was doing fine and no more overheating...but the problems back again. I'm overheating at idle. My fans are working when I put a paper click to the coolant sensor on the t-stat. But now it's not turning on by the sensor. I just replaced it and bled the coolant system still not working. Could the sensor have gone bad already? Or am I missing something else. It's a brand new Oem sensor.

 

When the engine gets hot touch both radiator hoses. Are they the same temperature? Or is one colder than the other. Be careful, because the hose are around the temp of boiling water.

 

Thanks for the reply, I tried that and they do feel a little different in temp. So
I am guessing your referring to the thermostat. That's what I get for getting a aftermarket t-stat.

Now just a random question, do your know what kind of psi rating for a radiator cap I need?

 

The cap is something like 16 psi.
