There is a bleed screw on the thermostat housing. Remove the screw with the engine loose. Ounc you have pure coolant and no air you can close off the bleed screw.

It doesn't have a bleed valve for the power steering.


procedure on how to bleed air out of coolant system on 97 saturn ls


This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.


how do i bleed my accord v6 2000 coolant system, its has air and the rev's gone up & down......


There is a small brass valve on the top of the thermostat housing where it attaches to the top radiator hose. Loosen it and then fill the radiator until coolant comes out of the valve and then quickly close it. This is only for an impala with the 3.8 liter engine though I believe there are two valves on the 3.4.


You have to use a radiator funnel kit from napa part # 77-4000 runs about $20. Chevy vans do not have a bleed screw.


It is not necessary to bleed the coolant system. If you mean "drain" the system, there is usually a plastic plug on the radiator or, you can pull the lower radiator hose off.


To bleed the coolant system on a 1998 VW Beetle, remove the top from the overflow tank. Run the car for 10 to 15 minutes to force any air out of the system, then check the coolant level. Add coolant as needed.


there should be a air valve on the engine that you can bleed the bubbles out of the cooling system.


Start by taking the top off of the coolant overflow reservoir. To bleed the system, run the 1998 VW 2.0 Beetle about 10 minutes, then check the coolant level. Add coolant if needed, then replace the reservoir top.


what is the year make & modle of it??



As you did not include engine or Year info I will give a general answer. Look on the top of the engine, most GM products with a bleed system have a small brass pipe thread plug in the top of a black or aluminum casting. This is the bleed point, loosen the plug or valve and add coolant to the system until it flows from the bleed, tighten up the bleed. Done. Repeat if needed.


Is the question how to bleed a Buick 3800 cooling system? I would say open that little petcock by the themostat housing and release all the air as you fill the system with coolant. When coolant comes out instead of air all the air is out.


If it has bleeder valves then use them to bleed the system, if not, jack up the front of the vehicle as high as possible. Remove the radiator cap and start the engine. Add coolant to keep the system full. This will allow air to escape.


You should not need to bleed coolant. Ever. If the coolant is filling up on its own the stuff in there is not coolant and you have a big problem.


If there is not bleed valve for the coolant you will have to do it manually. Fill the radiator up and start the car. After it warms up the coolant level will drop, refill it.


To bleed the coolant in a 1995 Dodge intrepid locate the drain plug on the underside of the radiator, un plug it and pour new coolant in the system. Close the plug and while the engine is running find the coolant pressure valve and loosen it to relieve pressure. When bubbles stop forming there is no longer air in the system.


Low coolant level or possibly air trapped in the system. Bleed the system and check the coolant level in the radiator not the reservoir.


It is a brass fitting on the top of the thermostat housing.


There is no need to manually bleed the coolant system on a Northstar, the system is self bleeding. The small hose on the side of the overflow tank is the self-bleed line. If, by chance, this line is obstructed, then the air will be trapped & cause overheating problems. Be careful is the plastic nipple on the side of the overflow tank as it is very weak & cracks easily.


The Villager engine does not have a coolant bleed valve.


To bleed the cooling system on a 1996 Olds Cutlass, locate the bleed valve, which is on the front of the engine above the water pump. After making sure the cooling system is not under pressure, open the valve by turning it counterclockwise. Fill the radiator with coolant until no air comes out the bleed valve, and a stream of coolant begins to flow from there instead. Tighten the valve and close the system to finish the job.


If by "bleed" you mean drain, disconnect the lower of the two hoses (do not confuse with the pipes from the AC evaporator) and drain the coolant into a bucket. If you are flushing the system (which you should if you are changing the coolant anyway), dont bother draining it, most of the coolant will flow out anyway, just do the coolant flush and fill from the radiator.
