Look on your exhaust manifold. What you are looking for is a little bleed screw. Mine is painted blue. Yours maybe a different color. When you find it start your engine and let it idle for 3-5 minutes. Make sure your heat is turned on full. With the enging running turn bleed screw counterclockwise till water starts shooting out. Let the water continue to shoot out until you get a steady stream. Once you get that steady stream then tighten. Your system is now bled.

SOURCE: how do you bleed air pockets out of cooling system in 99 grand am

If a valve is expose on the upper heater hose piping crack that open only when the engine is warmed up for at least 15 minutes. If no valve is seen you will need to loosen one of the heater hose clamps ever so slowly to let the air out. The process to loosen the clamp is not recommended unless you do this first..... When the engine is COLD loosen a hose clamp and remove the hose and put it back on. Thighten the hose clamp snug only. The start the engine to warm up. In about three minutes see if you can twist the hose to move on the fitting. If you can snug the clamo a lttle more and check again. You do not want the hose to come off if too loose. Now that the engine is warmed up for 10 to 15 minutes shut OFF the engine and barely loosen the same clamp 1/4 turn at a time until coolant trickles out. Listen carefully for air escaping too. Air pressure does built up only when the engine gets hot and the air pocket does not move when the engine was cold with the hose removed beforehand. If no air was released upon this proceedure you have a blockage in your system and flushing maybe the only other option using pressure instead forcing the coolant out. Get a can of coolant flush before the power flush proceedure. A radiator pressure tester can be used to power flush with an air fitting adapter installed in place of the guage

SOURCE: how do i bleed the brakes on a 1999 Pontiac Grand

Bleeding the Brake System
When any part of the hydraulic system has been disconnected for repair or
replacement, air may get into the lines and cause spongy pedal action (because
air can be compressed and brake fluid cannot). To correct this condition, it is
necessary to bleed the hydraulic system so to be sure all air is purged.

When bleeding the brake system, bleed one brake cylinder at a time, beginning
at the cylinder with the longest hydraulic line (farthest from the master
cylinder) first. ALWAYS Keep the master cylinder reservoir filled with brake
fluid during the bleeding operation. Never use brake fluid that has been drained
from the hydraulic system, no matter how clean it is.

The primary and secondary hydraulic brake systems are separate and are bled
independently. During the bleeding operation, do not allow the reservoir to run
dry. Keep the master cylinder reservoir filled with brake fluid.


  1. Clean all dirt from around the master cylinder fill cap, remove the cap and
    fill the master cylinder with brake fluid until the level is within 1/4 I n.
    (6mm) of the top edge of the reservoir.
  2. Clean the bleeder screws at all 4 wheels. The bleeder screws are located on
    the top of the brake calipers.
  3. Attach a length of rubber hose over the bleeder screw and place the other
    end of the hose in a glass jar, submerged in brake fluid.
  4. Starting at the right rear proceed in this order left front, left rear and
    right front.
  5. Open the bleeder screw 1/2 - 3/4 turn. Have an assistant slowly depress the
    brake pedal.
  6. Close the bleeder screw and tell your assistant to allow the brake pedal to
    return slowly. Continue this process to purge all air from the system.
  7. When bubbles cease to appear at the end of the bleeder hose, close the
    bleeder screw and remove the hose.
  8. Check the master cylinder fluid level and add fluid accordingly. Do this
    after bleeding each wheel.
  9. Fill the master cylinder reservoir to the proper level.

Changed a radiator today, drained system. Hot water will not heat now. Heating and radiators are working ok


Helen, if it is the radiator in your car that was changed, you may have air in the cooling system that needs bled out. May also be a failing water pump, thermostat,etc.

Why my 2000 s/70 volvo temperture hand goes to hot when driving i change the radator now this my problem


Rodney, first thing I can think of, the coolant system has an air lock in it. when changing a radiator now a days, the coolant system has to be bled properly for a successful install. Other than bleeding for air, you may have a faulty plugged core radiator. You did plug your fans back in right. links below on how to bleed air from cooling system.

02 ford explorer 4.0 overheating and suddenly blowing cold air, then hot again while engine runs cool but not long


Most likely you have air trapped in your engine, particularly in the heater loop. You need to properly bleed the air out of your radiator cooling system. The hot and cold blasts of air coming from first hot water followed by air.
Read up on how to bleed air out of your radiator system. Some systems are very difficult to bleed.
If after doing a good bleed of the radiator system the problem returns, you may have a bad head gasket or other leak in your cooling system which is injecting air into the cooling system (radiator/water cooling system).

My car is overheating and the heater is not working. I've been told it's a blown head gasket. I've also been told that I need to bleed my cooling system. So my question is, where is the co


If you have a blown head gasket, surely you will overheat because some hot combustion gases are entering your cooling system. No way you can remedy it by bleeding the system. Bleeding the system is just removing the trapped air in it. Running the engine with out the radiator cap will do the trick.

Bleeding the cooling system


look at your top radiator hose is there a small bleed valve at the top of the thermostat housing when the upper hose attaches 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 there is 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

How do you bleed air from the cooling system on a 1995 pontiac grand am gt 2.3


A good way to do this, is while the engine is cool. I say again, COOL.

Take the radiator cap off, and start the engine, slowly pour coolant into the radiator until it stops going down. look for air bubbles, once the air bubbles stopped, it should be good to go.
