It might be easier to get the air out by starting the engine when it is cold with the radiator cap removed and run it until you see the water running across the cap hole (circulating when the thermostat opens).

SOURCE: cant find bleeder valve foe coolant system on 96

dr_greg is incorect. The bleeder valve is on the thermastat housing near the intake manifold. Follow the hose from the top of the radiator to the the engine. Look for something that looks like a 12mm head nut with a metal nipple comming through it. If you change your coolant but do not open this valve untill coolant flows from it you may cause an air pocket to remain in your engine, possibly causing your car to over heat.

I have 85 Civic 1500. , 124,000 miles, the cam sprocket loosened and bent some valves. Head surfaced, new cam and new valves on #3, Prof done. Now no heat, mechanic checked the heater and mix controls,...

The air needs purged from the system. the mechanic should have done this. Any way remove the radiator cap ,start the car, Have some coolant ready to pour in. As the car starts to warm up it is going to push some coolant out.when this starts rev the engine up some , this will draw the coolant back down.add some coolant keep the engine revved up. at some point you will notice the the level drops alot this is the air getting to the radiator. Add more coolant. install the cap. It takes higher rpm's to push the air threw the system. You might do this a couple of times. but this is the fastest way I have found to purge air locks in the heater core( no heat). Keep a check on the coolant level in the resevoir. because if this gets to low it will **** air again.

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,...

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.

Engine gets hoat some time, no heat from heater. top hose seems hot to touch lower hose is cool. Drained radiator few weeks ago and problem began

Theres a strong possibility being you just changed the coolant a few weeks ago that theres air in the cooling system not allowing the coolant to cirrculate properly, look at your top radiator hose is theres a small bleed valve at the top of the thermostat housing when the upper hose attactes to? If so loosen the bleed valve and allow the cooling system to purge the air out of the system you can tell when the air is out of the system when a steady stream of coolant starts to flow out of the bleed valve, if theres no bleed valve take the top radiator hose off of the engine side and allow the cooling system to purge the air out through the top of the engine that way, but it definatly sounds like theres air in the system not allowing for the cooling system to cool properly...

Received P0455 Evap System Large Leak Detected - 2004 Cavalier

your problem is probably a vacuum hose that goes from the purge valve to the gas tank (crack or broken hose). There should be two of these check both. A broken vacuum line will make the purge valve make a clicking noise that can be mistaken for noisy engine valves.

Over heating and radiator leaks. overheats after sitting at idle for around ten minutes. its a 5 speed manual transmission 2000 chevy 2 dr cavalier.

if there is a leak then of course you will get overheating from the engine..Be very careful as this can cause permanent damage to the head gasket and it will cost a lot more to fix..First try to stop this leak before you proceed further.

Running hot 1996 cavalier

please try a simple test for me. no.1: remove the radiator cap off the radiator. no.2: if you could see the see the radiator opening from within you car much better, then try to crank your car to an idle. if coolant blows out of the mouth of the radiator like an erupting volacano, then take note of this. no.3: while the engine is running at idle try to look at the coolant through the mouth of the radiator, if you see bubbles like washing your hands with soap and the suds trailing to a drain, then take note of this.

the reason why i'm telling you all of this is that, the coolant should flow like a clear stream. you don't have to worry about purging the system of air because, the water pump is already situated a few inches below the highest water capacity of the radiator. it means that if you drained your system and refiled the radiator to the brim, just start your engine and add a few more coolant to fill it up because the running engine simply purges the waterpump of air.

now, if you tried no.2, and you did see and somewhat like an errupting volcano, that means your engine is in serious trouble, so is no.3. however, a tolerable bubble flow is still possible but your valve clearances should be tuned if this happens. excessive bubbles accompanied by blow out of coolant means your combustion gases are seeping through the head gasket due to a damaged head gasket, warped cyclinder head, cracked cylinder head, or even a cracked cyclinder liner(or bore where the piston glides up and down). think back! did you ever experienced overheating you car to a point where it stalled completely? then, you need a thourough engine checkup.
