Question about Chevrolet Cavalier

2 Answers

I have a 91 chevy cavalier 2.2 I'm about to replace the water pump, and have already replaced the thermostat. I'm wondering if there is a valve that I can use to bleed the air out of my coolant system, where it might be or another method of bleeding the air out.

The easiest way to purge air from the cooling system is to raise the vehicle so the radiator cap is higher than the engine. Make sure the heater control is on the highest setting. Remove the radiator cap and let the engine run. When the thermostat opens, the coolant level will drop in the radiator. Add antifreeze to bring the level back up to the top. As the coolant level drops again, add more antifreeze. If the thermostat closes, the coolant may overflow out of the radiator, so be careful of hot coolant. Continue to let the engine run, and watch for the coolant level to drop again when the thermostat opens. Continue to do this until the coolant level stabilizes. Put the radiator cap back on and lower the vehicle.

Go to YouTube.com and search for "1991 chevy cavalier water pump replacement". They have several videos on Cavaliers, one for a 1991 with a 3.1L engine. You didn't state engine size, so scroll through the search results to see if you find a video for your model engine (could be a different year though).

has the thermostat been changed lately? did the fluid leakage start about that time? check the thermostat housing and the heater hoses. i would also check that the correct gasket was used on the water pump. it is not unheard of to get the wrong gasket with the water pump. they may look right but a small difference can make all the difference. is it the correct water pump? are all the bolts on the water pump tightened properly?

98 Chevy cavalier overheating


That is really quick, like you are getting no water flow at all. Make sure that a radiator hose is not collapsing enough to stop the flow. If possible on that model, take off the radiator cap and shine a light to see if the water passages in the radiator are clogged up with rust or sediment. If this started after the new thermostat was installed, make sure it was not put in backwards.

In order to access the door u mention which is called the air temp control blend door u must remove the entire dash assembly, most likely the door's actuator motor is defective, very common part that fails.

1996 Chevy Cavalier blown head gasket


Pull the spark plugs out and see if they have a brown tint to them and smell funny. You can tell a lot by the spark plugs. That could tell you if you're getting anti freeze in your cylinders. These engines are bad about head gaskets and cracked heads. To replace the head gasket you're probably looking at about 480.00 labor and about 200.00 in parts and machine work, unless the head is cracked, then you're looking at more money.

I am a mechanic in a shop in my area and replacing a water pump on your car would not cost that much money. I checked the prices of a water pump and thermostat and I would not charge more than $250 for the job. I pays 1.5 hours labor to replace the pump. I hope this is helpful.
