Does the electric fan work...if not the thermatic sensor is faulty, quite common.

Engine heats to proper temp, heater fan works, already replaced termostat. heater core doesn't seem to be leaking.

Find where both hoses are going to the heater core from the firewall side after engine is up to temp.Touch them with your hand.If they are both quite warm the water is flowing thru the heater core. If only one is hot the core is stopped up. If both are hot and still no heat the heater door in the heater box is staying closed.

My heat stop working,i was told it is the termostat can not find the termostat

the t-stat is located on the front side of the engine underneath. you actually have better visibilty underneath the vehicle. i would perform a flush prior to replacing any parts. if it was the t-stat, you would also have over heat issues. a t-stat is nothing more then a temperature sensitive, mechanical restriction in the cooling system. wax pellets heat up during the warm up process allowing the engine to heat more rapidly during cold start and push the valve open allowing for flow to the radiator. go to your local parts store and for about $10 you can get a flush chemical which will help flush your system of contaminants and corrosion and then refill the system with fresh coolant and distilled water. be sure that the system is totally full and bled or you will know the first time you take it out and it over heat due to lack of fluid.

No heat

GM and no hot air while over heating is a common problem. a bad intake manifold gasket is the usual suspect. it can lead to air in the cooling system and restrict the flow causing it to overheat and keeping the thermostat from working. in time it can cause the engine to seize. there are other tings it could be too, it could be a bad radiator cap, a leak in a hose you don't see yet and a loss of fluid could take time to notice and yes it could be the thermostat is bad. a trip to the mechanic for a diagnostic my be cheaper than throwing parts at it.

good luck

I have a 1996 volkswagon jetta and I removed the thermostat but the temperature guage is still going pass half. Is there anyway to get the air out of the system and solve this overheating problem?

without termostat, start the car. in one minute ideling, both hoses from cooller should be warm.
If only top one is warm, check if the hose from front wather cooller to expansion tank is blocked (small one on top). usualy it is blocked on wather cooller itself .if OK, change wather pump.
also check if presure is bildinh inside wather sistem. that indicate head gasket or head itself should be checked
If you had remove the termostat, there can be no air inside the engine (if wather is inside).Even with termostat present, VW has no problem with air pockets.If your temp.go pass half when car is standing still, that is ok, but when driving must drop down.
