2007 PT Cruiser Overheating
I have replaced the thermostat, radiator, and fan, flushed the lines, hoses okay. It sometimes overheats and as soon as I turn the heater on the temperature goes down. Sometimes I smell coolant. Any other ideas why it is running hot? Water pump is circulating also.
If the temp goes down when you turn the heater on that tells me the radiator cannot get rid of enough heat. Try some Redline water wetter in the radiator and it may help reduce the operating temperature. You may need a heavy duty radiator with more cooling capacity.
If you are smelling coolant, where from? A common cause of overheating is from a leaking head gasket. Check for bubbles in the radiator when it's running. Check for 'milkshake' in the engine oil, caused by water leaking into the oil, which gives it a frothy chocolate milkshake look. A possibility is your heater core is leaking, if you smell coolant inside the cabin. Even a small leak can cause steaming of windows. You may have one or the other or both.
