Re: 06 4.7 slightly high engine temp- i need your help
one thing i always do to remove the air from the cooling system is.
after filling the radiator to the top, with the radiator cap off start the engine and crank the heat and turn it to defrost. once the thermostat opens you should see the coolant level drop. this is cause its refilling the heater core and its purging the air from the system.
dont shut it off yet leave it running and continue to fill it up once you have reached the top of the radiator wait til you see all of the air bubbles stop put the cap back on and let it come up to full operating temp while leaving the defrost on. once up to normal operating temp shut it down let it cool completely. once completely cool take the cap off again check level again and top off if needed. and thats it.
