I had the radiator & fan replaced. Since then I have been going through a lot of antifreeze and my car runs hot very fast. It does not smoke or shut off though
If your engine is overheating, Try this procedure:
Have the cooling system pressure tested with a special tool and see if the source of the leak is the water pump, also feel under the pump for antifreeze.
SOURCE: Very hot car.
I'd test the fan by connecting it directly to the battery to verity it is functioning. If it is, check the relays that control the fans they should be located in the fuse box in the engine bay. If the relays are ok the only other thing that could be causing the problem is the temp sensor on the radiator.
SOURCE: replaced cracked radiator in 2000 Chrysler LHS but car still overheating. What could be the problem?
fix the radiator first.because coolant temperature sensor need to be in antifreeze.when antifreeze get up to 190 degrees. the coolant sensor act as a thermostat.it resistance decrease then the pcm will command cooling fans to run.if antifreeze low the coolant temperature sensor not going to work. engine is going to over heat.
SOURCE: 2001 pt cruiser running hot after changing
I have a 2001 PT and it overheats the rad fan will not turn on. I took it to auto zone to hook it up to the code reader and it said that BBECM has detected an open or shorted condition in the radiator fan relay circuit Probable cause open or shorted high speed radiator fan relay.
What dose this mean is it a relay or the computer. I have read alot about the pcm needing re-programed is this something the Chrysler deal should take care of it seem to be happening to alot of people.
