How do you bleed the cooling system of a 2004 Pontiac grand prix gt?
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.
If the low coolant light is on when you just replaced the radiator in a 1994 Pontiac Grand Am with a sealed radiator system what could be the problem?
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
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…
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…
