Engine Cooling problem
2003 Cadillac CTS 6 cyl Two Wheel Drive Automatic 105000 miles
I've got an error code P0128 on an 6 cyl 03 CTS Caddy. The book claim's engine coolant temp below normal. Not sure but seams to me that the thermostat is stuck open. Could be a bad sensor but want to say it would go full scale if faulty. I read from a previous post that you have to go behind the timing belt to get to the thermostat. What speical tools are needed to reset the timing? I don't mind getting greasey and have re-built many a motor with good results. The problem I have is paying the dealership $500.00/700.00 labor when I could do this myself on any given weekend.
