Hi,
Try stopping on a steep incline--does the heater stay warm? If yes, what you have is an air bubble that hangs at the heater hose until pressure from the water pump blows thru it as the engine speeds up. Park on an incline, open the radiator cap, run the engine until the thermostat is open, turn the heater on, crack open any/all bleed ports to release any trapped air, and fill the radiator to the neck. Wait until the level stops dropping and make sure bubbles don't continue to come up. If they do, you may have a blown head gasket that will keep forming these bubbles until you change the gasket.
Please let me know if you have any questions and thanks for using FixYa.
No, because it blows cold air when it gets hot. There is air in the system or the coolant is low. Intake manifold gaskets are a very common problem on these engines and if left unattended to can cause even bigger problems such as head gaskets if the engine over heats too much. Check the coolant level and if it is low, look for leaks at the water pump, radiator and especially the intake manifold where it meets the head. Also, pull the oil dip stick an/or the oil cap to see if it looks milky. If it does, there is coolant getting into the oil.
