I have a 94 Eldorado and I don't know what size engine off hand I know it is a NorthStar 32 valve.

But I run the car and just started to go up in temp just when I pull on the highway. One time it said hot and turned it self off trying to get back home.

Next day started up great and then temp started to climb in a short bit.

I have a new radiator new thermostate new hoses, new water pump what is going on now??

Can this be a recall thing??

Thank you,

Robert

I have the same car as u and I'm have the same problems. It all started with my core heater going. I had that fixed and the next day after driving for NJ to MD for about 2 hours my car started to overheat and it tued its self off just like yours. I drove it after that for a day and it was find. Later that day I drove it and watched it temperture go up. Its in the shop now and they can't get my car to overheat for them. I told the to go ahead & change the therostat on it believing this will solve my problems. was the the correct move to make?

Did anyone every figure out the problem? Mine does the same thing after driving about 20 mikes. New thermostat and radiator have been installed. Somebody suggested maybe to replace the head gasket.

Thanks

Verify that your cooling fans are coming on first of all, If you turn a/c on, they should come on, or let engine run and heat up. Assuming that the coolant is full, and of proper concentration, I would recommend a block test for combustion gases in the cooling system. If it is performed with a gas analyzer, anything over 3 ppm hc indicates internal leak. There are also kits that perform the same test, using a fluid that changes color in presence of hydrocarbons, although they are not as accurate.
