I have a 2001 PT Cruiser
5 speed with about 105,000 miles. About a year ago I had the clutch
replaced, drive belt and brakes
on the front. For about a year off and on, my car has overheated and/or I could hear my coolant boiling, but only about 2 times until about 2 weeks ago. Since then, I have had the fan motor and relay replaced and most recently the thermostat
. They refilled my coolant that time also. I drove the car (without air conditioning) after picking it up, about 1/2 mile, and when I stopped, I noticed there was coolant on the ground and before I turned it off I could hear it boiling but it was not overheating at that point. It was evening at that time, so the outside temperature was about 57.
I continued to drive it to my destination which was about another 5 miles and once again I noted that the coolant was boiling, but no overheating. I drove it back home which was about 10 miles. During that trip is was not overheating, but when I got home, I could hear the coolant boiling.
Today, I took off and the temperature gauge went to 1/2 way after about 3-4 miles, which it usually does. Then I stopped for 1/2 hour, could hear the coolant boiling when I stopped. Then I left again and drove about 1/2 mile and all of a sudden noticed that the car was starting to overheat. Also, as I have noticed in the past, before the car overheat, it starts to hesitate and the tachometer fluctuates to just below 1000 back to 1000. When this starts, the gauge starts going up. I had to drive another 1/2 mile to get an exit where I could park and the temperature never went into the red. Also, just to let you know, I ran the heater on defrost which seems to help keep it from going red.
I sat for about an hour before starting home again, and it did not overheat on the way home, but I could hear the coolant boiling when I stopped.
What the heck? Any full proof ideas?
