First remove the plastic engine cover by un-screwing the oil filler neck from the engine (not just the cap but the whole tube). Lift off cover. Then find the thermostat housing (follow large hose coming from top of radiator). Get a rag or towel so coolant doesn't splash on you. Locate the bleeder screw on top of the thermostat housing (10mm screw). Run the engine for 5 mins. or so until it gets up to temperature. Leave engine running and slowly turn the bleeder screw counter-clockwise until only coolant is coming out. Re-tighten screw and replace engine cover. I just replaced the thermostat on my '04 so I know it works.
I just did this and the screw is a two piece screw, the 10 mm part need not be turned on my car ('04 GP GT2), instead the top part of the screw which was a 7 mm is to be turned to let the system bleed off.
A person can find a diagram of a 1998 Pontiac Grand AM cooling system in the cars maintenance manual. They can also ask a person at an auto part store for a print of the diagram.
Open the t/stat bleed valve or if there is a radiator petcock. run the engine while servicing as they are prone to air pockets in the cooling system.
There is a high probability that the system needs to be bled. As in bleed the air from the system. Just filling the system is not enough. You need to warm the engine to get the water flowing, then switch off and bleed the air out. Yes there is always some air and it gravitates to the highest point of the cooling system. I hope this helps
when it is cold take the cap off the radiator and start the car and let the air out The above answer is incorrect. The cooling system on the Grand Am requires you to bleed the system. There is a bleeder screw on the top of the motor, just follow the black tubing and you'll see it.
Cooling fans won't stop running in the cold on a grand am gt 2001
Total Cooling System Capacity (qts): 12.3
There is a schrader valve on the fuel rail that will allow you to blled the system. This is not normally necessary as the air will be pushed out by the fuel pressure.
on the side of the thermostat housing there is a small screw with the motor is running make sure the heater is on loosen the screw let the water run until you see a steady flow then tighten back up. I disagree with the previous poster. The cooling system is bled by loosening the screw on the metal pipe just behind the water pump housing. The pipe goes upward off the housing and has a bleed screw on the end of it. To Bleed the cooling system, turn the heater to full hot and open the screw and add coolant to the resevior until you get a bubble free flow of coolant from the bleed screw. At this point the system is bled and just tighten the screw.
Check the temperature sensor
have you tried removing return line to bleed system ?
where is my cooling fan swcith to my 1994 pontic grand prix
These engines take care of themselves... They have a air bleed tube coming out of the water outlet, which is located under the power steering pump on the drivers side. This tube runs back over to the fill tank. This system does not have a cap on the radiator, just on the fill tank. This is correct on the 97 Buick Skylark 2.4 Quad 4 which I have.
It should be a bleeder screw connected to the cooling system, it might be two.If you find it,you should open one at a time.Pour coolant into the system slowly,until coolant start coming out of the bleeder screw and then close it . DO it to the second screw too.Now if you do not have the bleeder screws.Pour coolant into your system slowly and squeeze the top hose until no bubbles come out and the coolant level should go down at this time and then pour alittle more in there
Buy a kit at Wal-Mart or auto parts comes with fitting adaptors and instructions
your probably getting transmission fluid in your cooling system from the cooler in the rad. replace your rad
there is no reset you have replace the low coolant sensor and flush cooling system and use dexcool coolant.
The best way to bleed air in any car's cooling system is to elevate the front of car so rad cap is the highest point of vehicle. Then just simply leave cap off while motor idles. Add coolant as necessary over the course of 30 minutes.
The 1996 Pontiac Grand Prix cooling fan sensor is located on the front of the engine. The fan sensor can be found just above the thermostat.
227 degrees fahrenheit
it should be in underhood fuse and distribution box.
The ticking noice from under the hood comes from the cooling of the thin metal work near the exhaust system. The ticking is it cooling off and shrinking slightly.
Could be,Low on coolant,A stuck closed faulty thermostat,A faulty cooling fan motor/system,
Never ask this questin again OK you STUPID AND IDIOT
The cooling system on this vehicle does not use a radiator cap on the radiator but on a remote tank. It may have a different (larger) cap on it than what you are used to seeing on the radiator.
