Sounds like you dont have enough coolant in the system. wait till it is cold fill up the coolant system, then start it up. as the gauge reaches operating temperature watch your cooling fans and see if they turn on. if it just gets hotter and hotter and the fans dont turn on then you may have a bad connection, blown fuse, or relay. if the fan turns on but your car continues to get hot replace your thermostat. if you are still having problems it is most likely your water pump. you may want to check the weep hole located on the bottem side of the pulley, if it is weeping water then the bearing is toast and you need to replace it, you can also loosen the belt and wiggle the pulley around, if it moves around its likely toast if it seems good and tight it should be fine, also check all heater core hoses, bypass hoses, radiator hoses for loose ends, cracked hoses, bad fittings, etc.. you can check the radiator by looking for drips while its running or my taking it in to a radiator shop and having it pressure tested.

Van blowing cold air

It has air in the line. let ir idle with the radiator cap off for a little while and the air will work its way out. You may have bigger issues, but I do not think you need to clean heater core because you get heat sometimes. Do you see a lot of bubbles when you take the radiator cap off when running, head gasket if so.. You can take the cap loose while the engine is running, but not after you stop it, it will be to hot. Good luck

Air pockets in radiator

Air can be purged. While your engine is cool remove radiator and reservoir caps. Place funnel in radiator. Turn heat to the highest position and start vehicle. Add coolant to radiator as needed while vehicle warms up. You should see bubbles coming out of radiator. Fill reservoir to between cold and hot fill lines. Replace caps when bubbling stops but before coolant temperature reaches normal operating temperature. Never remove the radiator cap until engine has fully cooled down.

My heater is not blowing hot air consistantly...the fan works, the ac works, but the heat blows hot sometime and not others

Sounds like you have an air pocket trapped in the coolant system.This will cause intermittent heat and especially at idle with little water pump circulation.Try to remove the reservoir cap when not under pressure and start the engine.allow the engine to reach operating temp and allow any trapped air to escape for about 30 minutes.turn off the engine and allow it to sit without the pressure cap on for around 5 minutes.Top off coolant as needed and replace the cap.Let's see what happens from there.Hope this helps,

you have air trapped in the system.
Park facing uphill (on car ramps if you have them).
with cold engine, remove radaitor cap and fill radiator.
Fill reservoir.
leave cap on loose.
Turn on heater.
start engine and run until upper radiator hose gets hot (meaning thermostat has opened).
Check coolant level and top off. Repeat until temp gauage reads normal and heat is coming from heater ducts.

2001 pt cruiser no heat

did you check the fluid level by removing the rad. cap? Radiator should be full to top. If Chryslers are low on coolant, the heater will not blow warm air.
