Overheating issues.

I have an overheating problem. On a 2000 300m Chrysler.
I replaced the water pump, new timing components, new thermostat (I have changed it 3 times). The fans are both working. There are no leaks. Good coolant circulation. I am afraid head gaskets are put wrong, how would I know?

**When I turn the heat on the tempurature drops to the middle.

Please help.

What would make you say that? Did you just have head gaskets done?

Yea I was told the head gaskets were bad and the water pump. They were replaced and now my car is overheating. Is there a difference between the right and left head gaskets if they were put on the wrong side?

No, but there is certainly a lot more to do in that job than just toss gaskets on it. The heads needed to go out to a machine shop for testing.

Sorry for butting in but your comment on turning on the heater caught my attention. My old minivan acted like that years ago. Ran warm at anything over 60 mph, (when the higher air flow should have helped), and 60 degrees. It was caused by the cooling fins in the radiator being rotted away. Running the rear heater always brought the temperature down.

Also look for a butterfly collection blocking air flow through the radiator.

Turning the heater on merely added some additional cooling to a system that was already overloaded. I suspect there were other issues with the head that weren't resolved.
