You may have a blocked heater core & if so you will have to reverse flush it. You can do this with a garden hose by carefully removing the in & out hoses & reversing the hose back & forth until it is flowing without restriction. Good luck!

I have a 1999 Pontiac Grand Am GT that keeps Overheating. I've changed the Water pump, Radiator, Rehotwired the fans to alway come on right when I start the car and only go off when I kill it. It


With a over heating problem the first place you always check is the thermastat.Thermastats ALWAYS go.
In fact every two years I change the thermastat wether or not it needs it just to be safe than sorry,I live in a snow belt and nothing worst than having no heat in the winter.
Something else you might keep in mind, over heating can do allot of damage most people don't consider, the transmission lines are connected to the radiator which cool the transmission

No heat when stopped for traffic


1-your thermostate is stuck open half way. thermostate is a simple device that made of enlarging metals when heat is applied. it suposed to be in close position to allow engine heat up, when specified temp reached it opens and let it flow and radiator tries to keep coolant cool.when it is broken it stucks or it acts slow or it wont acts at all. in your situation it is stuck open half way. it allows enough water to be heated but flow is limited to heat cabin heater.

2-if there are cabin heater selenoid/selenoids for two different temperature for cabin left and right, on some instance those selenoid valves to adjust cabin heater stuck open or closed like thermostate acts on first case. so heat is not enough to heat up cabin heater.

MY A/C WORKS PROPERLY HOEVER THE HEATING SYSTEM IS NOT WORKING. AIR COMES OUT BUT IT'S COLD. WHAT SHOULD I BE LOOKING INTO?


a stuck or broken thermostate would do that if the moter temp takes a really long time to warm up the thermostate is stuck open and needs to be replaced if the moter warms up to fast or over heats the thermostate is stuck shut and needs to be repalced. the heater core its self could be plugged and may be fixed by back flushing with water if you do it your self flushit seperate from the moter to prevent what ever may have plugged it from re-entering it.

Heats up quickly after 5km.water boils and i ve to stop


The thermostate is probably faulty. Replace.
Other cause can be blocked cooling system. Needs professional equipment to check the pressure and circulation in the system.

I do not have enough heat in my 1994 dodge ram truck


I expect the thermostate is stuck partially open not allowing the engine to come to proper temperature. Replace the thermostate found under the goose-neck (follow the upper hose back to the engine) under this piece is the thermostate. Be certain to clean all of the old gasket material away and use a new gasket. Watch to be ceratin the thermostate is not put in upside down, if this happens your issue won't be not enough heat but over heating.
I hope this may have been of help,
Tom

Over heating


The water pump has what's called a 'weeping hole' built into it. If the pump is bad You'll se water coming out of the hole. When was the last time you flushed the radiator? It may be your radiator cap is bad, they should be changed once a year & the radiator flushed. You can also test ur thermostate. take out ur thermostate & put it in a pot of water so that the water covers the thermostate. Then put a cooking thermometer in the pot to & heat the water til it says 195. u should see the car thermostate begin to open. if it don't it's bad & needs replacing.

Heater in truck does not put out much heat


check the hoses going into the firewall for the heater and see if they are getting hot before you go too far. if one is hot and the other is cold then you may need to flush or replace the heater core.

I got a 97 galant and i.ve changed the thermostate but my heat still sucks. wat could b the problem


You have a heater coil that is not functioning properly. I think on your model it is located under the hood next to the firewall or under and near the glove compartment. This allows the water from the radiator to run through this coil which when the fan circulates the air, it passes over the coil and is heated.
