92 k2500 5.7 overheats sitting in gear.
My 92 k2500 4x4 with a 5.7 l and 4L80E is overheating while sitting in gear. I rebuilt the transmission,after no heat in cab and cooked tranny. I flushed the heater core,changed the thermostat and water pump and have been burping it for a week,even on stands. It still keeps overheating in gear. No water in oil,I get heat in the cab again,I replaced the exhaust manifold gaskets last year,I can't see any leaks anywhere,the return hose from the heater core gets warm and the thermostat is opening and pushing coolant through. When it cools and I squeeze the top rad hose with the rad cap on,I can here a click from the bottom washer on the cap,anyone know if that indicates a faulty rad cap?
