1991 Chevrolet C1500 Silverado 6 Cyl 4.3L
Why would my temperature not stay at a consistent temp?
The head gasket was replaced 3 months ago,I changed the thermostat 2 days ago,the fan clutch was replaced the same time as the head gasket
Is the engine overheating? Have you checked the coolant flow through the radiator and heater core?
