Engine Cooling problem
1995 Pontiac Grand Am 4 cyl Front Wheel Drive Automatic 130000 miles
My 1995 pontiac grandam quad 4 2.3l is overheating, no signs of a blown gasket or cracked head (no mixing of oil and coolant, no steam out the tail pipe.) I rebuilt the engine two years ago replacing the tstat, water pump, and hoses. Hoping to get lucky I just replaced the tstat, and had a pressure test, but nothing. The old tstat was working fine put it in boiling water and it opened. My next guess is a severely clogged radiator, but I can't see inside since there is only the cap on the reservoir can this be tested.
