2002 Pt cruiser coolant bubbling
While driving my car one night, I heard a crack
sound. Thought it was strange, but didn’t think
much of it. But then as I kept driving over a couple
of days, my temperature gage kept creeping up
more and more to the point where it almost
reached red hot. I then did a coolant flush to see if
maybe I needed new coolant, but it still
overheated. I then replaced the thermostat, still
overheated. I ordered a new radiator and put it in
today. I went for a 15 minute drive and my temp
gage stayed below the half way mark which was a
good sign. I drove it a second time and when I
parked and turned off the engine, I heard a really
loud bubbling/ boiling noise. My temp gage is
normal and is not over heating anymore, but after
the second drive, it made that bubbling noise. I
don’t think it is a head gasket because i checked
the oil and there is no coolant leaking into it. I also
don’t think it is the water pump because I my heat
still works. What else could it be?
