Wont even get warm
Bought a 94 gmc 4.3L v-6 for a parts chaser guy said only thing wrong with it was heater would not work. Well the engine will not get hot, put in a 195' stat guage just a little off 100 checked gague with known gauge. You can let this thing idle will not heat, pulled the grill bolcked the rad left 16 square inches of opening and it will just blow warm air and the gauge still just above 100. WTF any thoughts????

Those are essentually a V-8 with 2 cylinders not there,all front accessories interchange so the only place water is fed and stopped is the thermostat.Its either defective or not seated properly is my thoughts.

The T-stat could be in upside-down. Should be "pill toward engine".

I wonder if the heads have ever been pulled or a screwup from factory. the head coolant passage block-off plates probably are not installed in the head gaskets or are gone????!!!!!!
