welcome to the forum man.



for everyone else. This used to be my car, it was running great. A little background on the new owners location which is high altitude and cold weather. We are not sure if it affects the car. I think its probably the contacts on the sensors that maybe shrunk enough with the cold weather to cause a misread. Any input will be greatly appreciated.

I did, i replaced the whole cooling system just 2,000 miles before he purchased the car. He is posting because we have no idea what else it could be. Im thinking dirty contacts but I could be wrong.

temperature sensor is malfunctioning. clean contacts w/ contact cleaner and a brush then try again. if that doesn't work, replace the sensor.

Also, please use punctuation. It is hard enough to figure out what is wrong with a car. I don't want to have to hire a lunguist to translate your posts. You owe me $15 for his hourly rate.

if you do these items a la carte, you will be revisiting the cooling system for repairs many times, and you will get discouraged with each additional time you have to get back in there.

Do it right, do it once, do it all!

My bad. Didn't even notice lol. Lets help him out, he drove over 3400 miles. This started when he got to high altitude and cold weather. Do you think it could just be dirty contacts on a sensor?

You did what? Bleed the system?
You certainly wouldn't be the first to have to rebleed the cooling system.

Try it again:

When the engine is cold:

Start the car and run it at 2k rpm for less than 30 sec.
(This will allow enough pressure to build, and will help with the bleeding.)

Then

Engine off, but key on, position II

Turn heat temp to highest

Turn the analog dial between center vent to Red.

Fan speed at least On. (I set it to Max on my third and successful attempt on my most recent cooling overhaul)

Completely unscrew bleeder and pour, pour, and keep pouring into the ET, until the water comes out of the bleeder in a smooth bubble free stream.

Close up bleeder syphon excess coolant (i use a turkey baster) and close ET, go for a drive, with your heater on, and stay close to home, and have your distilled water with you to be sure and safe.

Check the level again when engine is completely cold, before the next time you set off. You may find that the level is a bit low, just top it off until the tip of the float is flush with the filler.

The nature of the situation does not suggest it is a mechanical issue. From one second to the next it reads it's overheating. Then he turns off the car and it reads cold again. What sensors could it be?
