1999 Chevy Spectrum 4 cyl Two Wheel Drive Manual
Replaced, fan clutch, themostat 196f, and still only makes about 160 to 170f temp. When driven down the road temp drops to 150f. Tried jacking up front and perging air. Same result, 160f max. Thermostat was a super stant 196 degree. Checked both heater hoses, both were warm, as was the upper radiator hose. Stumped !
