Ok so it's been well over 100 degrees here in Lawrence the past few days. I haven't driven my car because of it but today I had to run to wal-mart. On the way home my car over-heated. As soon as I noticed the gauge waaaaay up above H then I immediately pulled into a parking lot and shut her off. I had a friend pick me up and about 5 or 6 hours later went back to get my car. The coolant level seemed fine. I drove her home with no overheats (about a 5 min drive) but when I pulled in and put her in park...the rpm's shot up to 2100 and would not come down. I shut her off and don't know what to do. I'm scared. Any ideas?

I'll check but I just replaced the Tstat 3 weeks ago. :(

Any other ideas?

Besides a clogged radiator (you replaced that recently also, didnt you???) or coolant passage, I cant think of anything.........

Ahh... gotta love overheats. It could be -anything-!

For me, it happened on 100F and hotter days with the AC on. Here's what I did:

Had radiator removed to have it "cored" -- essentially removing the tanks and then gutting it out. My mechanic took it apart and noticed that the radiator was already in perfect shape, so he just put it back.

He replaced the water pump, which he said was making a whining sound.

The next day I washed and cleaned my engine compartment. I drove it around, then later that day opened the hood to show off my motor to a friend. Saw some water spots around where the radiator cap was. Replaced the leaky radiator cap with one that had a locking lever on it, and those water spots never came back.

So it was the water pump and radiator cap together plotting against me!

My friend, these problems cant really be diagnosed. :( Start with the radiator cap, then the thermostat, then the water pump, then find a place to remove and gut out the radiator (sounds like you already did that). Hopefully some or any of these will solve your dilemma. Best of luck to you...

At least it's running. 2100 is a weird one... Give it a try in the morning and see if it idles OK after warming up. You may want to disconnect the battery overnight to reset the ECU.
