    Did you bleed the system properly?

    Did all this just start after the water pump and therm(ostat?)
    First, make sure everything else is working properly then, let it just cool off. Overnight if possible. The next morning, overfill the coolant jug before your first drive.
    By the time you get the first drive cycle complete, all the air should be out of the cooling system and all is well now.

Heater blows hot air, then cold [ 1 Answers ]

My home heater comes on, blows hot air for 10 to 15 minutes, then cold air until we turn it off. If we leave it off for about 30 minutes, it blows hot air again, for 10 to 15 minutes, then cold again. What do you think is the cause?
