your heater core has air trapped in it take hoses off and run water through the top and it should fix your problem
have you flushed your radiator or changed the thermostat it could be stuck
The radiator may be plugged. Take it to a radiator shop.

A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.
Cooling fan could be faulty or radiator could be clogged or have slight leaks in it .
sounds like a bad thermostat even though it is replaced
check the heater core stopped up radiator
The piston or spring on the thermostat could be stuck.
Hi there, if you have flushed any engine and have changed thermostate there are only two options that are left; (providing that there are no leaks) 1. the thermostat is faulty / 2. your water pump is broken and needs to be replaced
Probably the thermostat is sticking.
Buy a new housing....not that expensive
If it heated up on you, chances are that you warped the cylinder head and now have a blown gasket. You don't give very much information, here.
