A lot of suggestions - however It could be numerous problems - I really think you need to consult a reputable auto radiator repair shop - you need someone that knows what they are talking about to physically look at the car to solve the problem - this will save you a lot of time and expense and heartache. ?

Those cars had huge problem with upper and lower intake plenum gaskets leaking. Look for coolant pooling around intake plenum.

SOURCE: running hot

Sounds like Clutch in your fan

The coolant level is right on, no hoses are leaking and the accessory belt is intact. You start the engine, let it idle and make a visual inspection. There's no sign of belt slippage.
If your car is like most, the cooling fan is mounted to its drive pulley via a clutch. Clutch fans operate at different speeds under different conditions to help reduce drain on the engine and to save fuel. When the engine is hot, the clutch fan runs nearly as fast as the engine. When the engine is cold, the fan runs much more slowly.
The fan clutch operation is regulated by a valve that is opened and closed by a thermostatic spring. The valve controls the flow of a viscous silicone fluid between chambers in the clutch assembly. When the engine is cold, the clutch is essentially disengaged, which is why the fan runs at its slowest compared to the engine's speed. As the engine warms up, the air flowing to the fan assembly becomes hotter. The hotter air causes the thermostatic spring to unwind and open the valve. Silicone fluid from the reservoir chamber flows into the main chamber, engaging the clutch, and the fan spins faster (though it's still slightly slower than the engine.

Hope this helps!

SOURCE: 1999 Pontiac Grand Am Overheating

I had the same problem on my 1999 Pontiac GA 3.4 litre. Replaced a bunch of stuff. It just kept pushing the coolant out the overflow once the temp got to 200 + like to drove me nuts. Ended up being that reservoir. If you measure the O.D. of the cap(brand new cap) and the I.D. of the reservoir filler neck there is no way it will seal(even tried to fit a different type cap,no luck). The system has to be able to build pressure or the coolant will boil out at 212. Causing the coolant to be pushed out the reservoir. Why? you say or How? did the filler neck increase in size. I dont know but GM has write ups about this problem. They say sand it with a piece of sandpaper to smooth it. Maybe someone sanded it way to much?? Around $40 bucks and I was on my way. Hope this helps someone.

SOURCE: My heater only blows out

check the vacuum lines going to the h-vac (under the dash where the blower motor is) make sure there are no vacuum leaks if there are no leaks start checking the blend door acuators firts locate all of them then start looking for the one that closes and opens the cold and hot blend door. turn the nob to heat and the other one to panel (not a/c panel just air) then if your not sure which one controls the hot and cold blend door start checking to see which acuator has vucuum going to them if there is vucmuum going to them but the acuator does not move replace it.but if it does compress take the rod lose from the blend door and see if the door in side the box is broken. if is not replace the climate controler on the dash. i hope this helps.

My coolant isnt circulating,i have heat but low power and high rpm.my car will overheat if I climb hills.


Hey Rayna,,, if you are sure the coolant is not circulating..??.. Then the water pump is no longer functioning.. OR....the coolant passages have partially clogged up.. When you replaced the thermostat , you should have reversed flushed the entire coolant system, check the radiator hoses for wear (they wear out from the inside), flushed the radiator completely..... Do the complete flush and check the hoses.. refill and see how much better it does..

99 ford contour gauge shows running hot. Change both sensors near thermostat and the thermostat. Flushed system and burped it. Ac or heat makes no difference. Fans seems to be working. Any ideas?


Is it ACTUALLY overheating? Check for heat at the top and bottom radiator hoses, and at both heater core hoses. If one is cold then your radiator or your heater core may be plugged and in need of a individual flush.

How to back flush heater core 2007 grand prix


drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.

I was wondering where the drain plug is to flush the coolant out. Also, what is the best method to flush out the radiator? I have a 2000 Grand Am.


There is a drain plug on the engine compartment side of the radiator at the bottom of the plastic tank. The best way to flush your cooling system is to get a Prestone Raditor Flushing Kit. You can use a garden hose to flush the system out.

My 02 Grand am V6 keeps blowing up all my water hoeses. it even cracked my radiator. it doesnt over heat until it brakes a hoes.


you got a restriction in engine block.its full of rust.flush block out by taking the thermostat out.remove the top hose to thermostat then move lower hose to water pump .place a container so the lower hose can catch the water as you flush out block with water hose.flush from the top where thermostat goes flush until you get a good stream of water from bottom is clear.before you start this procedure drain out antifreeze first. flush out over flow jug make sure its not stop up. and change the radiator pressure cap.
