Heater problem
1992 GMC Sonoma 4 cyl Two Wheel Drive Automatic
temp guage wont go past 100, but has heat in vehicle. Coolant reservoir seems to be losing anti-freeze. When engine is hot, removing radiator cap, there is coolant present. I replaced the thermostat, and still have the same problem. 3 ase techs all said thermostat, but i think all 3 may be wrong?????no coolant visible leaking, and inside windows continously steam up...sounds like heater core may be leaking, but nothing appears to be leaking from the fire wall nor is anything leaking into the cab on the floorboard! any ideas????
