Where to start?
parts replaced, intake gaskets (small leak), Thermostat, Radiator, radiator cap. Flushed several times. Truck will idle for hours without building up a lot of pressure in the system, can even remove the radiator cap slowly without losing any fluid, but drive it for five miles and the pressure will force antifreeze into the overflow tank and the hoses get rock hard. Idling with the radiator cap off allows the antifreeze to surge and splash out of the radiator. Heater works intermittently. Suspected a head gasket failure but No smoke in the exhaust, no anti freeze in the oil. Pulled spark plugs and the plugs and cylinders were dry. Pressure tested radiator with 14 psi and only lost 2 lbs in two hours. Tried using a block tester and the blue fluid remained blue.
Does anyone have any ideas?
