It has oil, it has coolant, no oil leaks. What could be the problem? I had wife run the heater full blast while she was driving it home, but this did not bring the temperature down. She also said the heater was not blowing hot air when she tried that..it was blowing cool air. Any ideas why it is overheating and how to fix?

hi from uk from your symptoms of what happened re temp guage risen suddenly it would indicate the temp sender unit on the engine has blown ie is earthing to engine via its screwthreaded body this is just a matter of replacing with a new sender unit hope this helps

Check the cooling fan switch. It appears your auxiliary electric cooling fan isn't going on when at idle. and engine temp increases. While you are driving, air is being rammed thru your radiator as you cruise along, so it isn't overheating, at idle, that isn't happening, and the fan should go on as the temp goes up. When the ac is switched on, the fan is being signaled to operate due to the heavy ac load on the cooling system.

it looks like that you cooling fan is not working, check the fan when temperature is up if its not working than check the fuse for the cooling fan, if its ok than check the current at the fan end if you fund the current the fan is faulty replace the cooling fan.

Hi, its not good news im afraid by you describing that with the coolant cap off and revving the car causes the pressure to build up and push the water back out it sounds to me like the head gasket is on its way out, what you need to do is take it to a garage and dont have a compression test done you need to have a gasses test done, you can buy these yourself if you want to and what it does is this.
its a plastic tube with blue liquid inside it then you take the coolant cap off and place this in its place you then run the engine and rev it up then you squeeze the rubber at the end of the tube and it then sucks the air out of the coolant and through this liquid then if it detects gasses from the engine in the coolant then this turns the liquid green and this is then telling you that the head gasket needs changing.
please dont let it keep over heating as this will cause the cylinder head to warp and you would then need to get it skimmed to make sure its not warped, get the gasses test done as a compression test dont give you a true reading as the engine is not running when they do a compression test.
let me know how you get on or if you need further assistance ok
plz rate this solution as i have a whole page of unrated posts, thanks

Know problem to check out.
-Check your coolant level, low coolant can cause that.
-A bad thermostat could cause that
-Bad headgasket could cause that too, but you have to use a headgasket test kit.
it hard to say what it is without doing any test on it.
good luck
