Raise the front of the car as high a s possible with a floor jack, fill the coolant bottle to the top with 50/50 solution of coolant, then run engine until it gets to high end of the normal zone but don't overheat it, turn off the engine and run cold tap water over the radiator core, the coolant will be sucked out of the bottle and air displaced from the system, do not let the coolant bottle go dry, monitor it constantly. If it still runs hot you have other problems not air trapped in the system.

How do you bleed the air from the cooling system of a 1999 v6 pontiac grand am


Refilling Procedure




Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL?"¢ coolant. If coolant other than DEX-COOL?"¢ is added to the system, the engine coolant will require change sooner: at 50 000 km (30,000 miles) or 24 months.






  1. Close the radiator drain cock.


  2. If previously removed, install the engine block drain plugs.


  3. When installing the drain plugs, use pipe sealer GM P/N 12346004.




    Important: On vehicles equipped with the 3.4L engine, open the coolant air bleed valve. The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.



  4. Fill the surge tank to the base of the filler neck.


  5. Start the engine with the pressure cap off. Run the engine until the upper radiator hose starts to get hot.


  6. If the coolant level in the surge tank is low, add the proper mix of coolant until the level reaches the full cold line.



  7. Important: After servicing the cooling system, and if the vehicle is equipped with an intermittent low coolant light, an occasional low coolant light may be encountered during some extreme driving maneuvers. This complaint should be eliminated by removing the surge tank cap and adding coolant to a level just at or above the full cold line when the system is cold.



  8. Install the cap onto the tank with hand tight pressure.



Recycling Procedure




Important: Dispose of used coolant in a proper fashion, such as in a used coolant holding tank. Never pour used coolant down the drain. Ethylene glycol antifreeze is a very toxic chemical. Disposing of ethylene glycol antifreeze into the sewer system is both illegal and ecologically unsound.



There is currently no approved method for recycling used DEX-COOL?"¢ coolant into new DEX-COOL?"¢ coolant. DEX-COOL?"¢ coolant can be recycled into new conventional coolant. Consult local listings for coolant recycling facilities in your area.

Location of coolant drain plug on side of motor for a 1995 mitsubishi montero


Not exactly,need to bleed air from system look topside of engine area for a bleeder port may need a filler reservoir full of coolant when doing this keep it full turn on heater full hot fan on high watch temp gauge if it gets hotter than normal reading and no hot air from heater ducts turn engine off ASAP it can be a pain in the grommet to bleed cooling systems but if you don't engine damage is imminent got to get air out of system drain plug on block does not sound right maybe it's on the top of block I have pulled hoses and filled system thru those and even used garden hose to force air out squeeze hoses rock vehicle and make big messes but don't overheat the engine from complete cool engine you have about ten minutes to get r done then let it cool down try again

How to Flushing radiator coolant


Hi, first you should get a drain pan to catch the draining coolant, then purchase either premixed coolant or straight coolant and cut it in half with water. then it is usually easiest to take off the lower radiator hose from the radiator and allow all of the coolant to drain out (but make sure that the engine is cool so you do not get scalded). then put the radiator hose back on and remove the radiator cap and start pouring in the new coolant. when it gets to the top of the radiator you can start the car and let it start warming up. be sure you still have the drain pan under the car because you will most likely have some spillage. when the car warms up to operating temperature you will need to keep gradually adding coolant as the air exits the system. This may take a half an hour or so. also make sure that you fill the overflow tank to the cold mark so you do not get any air back into the system. good luck

Drain cooling system


Make sure the engine is cold before you drain the cooling system. First remove the radiator cap. Under the hood on the bottom of the radiator you will find a drain plug. You turn it counter clockwise and drain the coolant into a container. After it has been drained add new coolant using the half and half (half coolant half clean water.) After having added the coolant. Be sure to add the kind of coolant that ,("goes with any color".) Replace the radiator cap.Run the engine to operating temerature then be sure to bleed the cooling system. They have a bleed screw near the thermostat housing . (That's where the hose from the radiator connects to.) Make sure all the air comes out from the bleed valve screw until coolant starts coming out. Tighten the screw and let the engine get cool again. check that there is coolant in the container where it says coolant only near the radiator.

How to flush radiator in a 2004 Mitsubishi endeavor


Drain your existing coolant from the coolant system there should be a drain petcock on your radiator along the bottem. Once the coolant is drained add water and a radiator flush solution, availeable from most auto parts stores, refill your coolant system and run your engine usually 10 minutes or more. Check the instructions on the type of cleaning solution you buy. Afterward drain the coolant system, flush with water by filling and running it again, then drain and service with proper level of coolant. Always remember to let your engine cool between runs to safely remove your radiator cap DO NOT remove the radiator cap if engine is still hot from running.

Overheating but reading normal on gauge . bubbling in overflow bottle .


Some bubbling may be normal. If it is overheating there may be air in the system and the hot coolant is not reaching the sensor, if this is the case you should bleed air from the system.

Coolant: Service and Repair
ENGINE COOLANT REPLACEMENT
1. Remove the radiator cap, the radiator drain plug and the rear heater unit drain plug (if equipped).
2. Drain the coolant into a container.
3. Flush the cooling system with water until all traces of color are gone.
4. Let the system drain completely.
5. Tighten the radiator drain plug and the rear heater unit drain plug (if equipped).
Caution:
^ The engine has aluminum parts that can be damaged by alcohol or methanol antifreeze. Do not use alcohol or methanol in the cooling system.
Use only ethylene-glycol-based coolant.
^ Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will cut down on the coolant's effectiveness.
^ Engine coolant will damage paint. If engine coolant does get on a painted surface, rinse it off quickly.
6. Refer to the following chart and select proper mixture of the water and coolant.
Antifreeze solution mixture percentage
7. Pour the coolant into the reservoir up to the FULL mark.
8. Tighten the radiator cap.
Caution: e If the coolant temperature becomes too high, stop the engine to prevent it from overheating.
9. Start the engine and let it idle until the cooling fan operates.
10. After engine warms up, perform the following steps.
1. Run the engine at 4,000 rpm for 1 minute.
2. Run the engine at idle for 1 minute.
3. Repeat steps (1) and (2) several times.
4. Turn on the main and rear heaters and verify that heat is coming from heater vents.
11. Stop the engine and wait until it is cool.
12. Inspect the coolant level. If it is low, repeat Steps 7-12.
13. Verify there is no coolant leakage.

2005 MGM - Need to change coolant


There is only one drain point. Drain the coolant from the system at the radiator. This will remove coolant from the engine. Be sure and have the heater set to hot. Flush the system with a water hose. Fill the system with a 50/50 mix of antifreeze and distilled water. Do not use tap water. Start the engine with the radiator cap off and keep adding coolant until it will take no more and you see no more air bubbles escaping from the radiator. If there are schrader bleed valves on the engine cooling system use them to remove any more trapped air. Put the cap on and start the engine and let it run for 15 minutes while you check for leaks. I would replace the thermostat at this time as it is just good preventive maintenance.

I Suspect that you have AIR in your COOLING SYSTEM Fallow Procedures BELOW to Insure there is NO AIR IN COOLING SYSTEM


Draining and Filling Cooling System

Draining Procedure

Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240,000 km, (150,000 mi) , whichever occurs first.

  1. Park the vehicle on a level surface.
  2. Remove and clean the coolant recovery reservoir.
Caution: Refer to Radiator Cap Removal Caution in Service Precautions.

  1. Remove the radiator cap when the engine is cool:
3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap.
Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound.

  1. Place a drain pan under the radiator drain valve in order to collect all of the used coolant.
  2. Open the radiator drain valve located at the bottom of the radiator tank. If only partial cooling system draining is required, drain enough coolant to perform the procedure.
  3. Open the air bleed valve on the thermostat housing 2 full turns
    1. Open the air bleed valve above coolant pump 2 full turns.
    2. Place a drain pan under the engine block drains in order to collect the used coolant.Important: Allow the coolant to drain completely.

      1. Remove both of the engine block drains.
        • The front left engine block drain is located between the starter motor and the engine oil filter.
        • The rear right engine block drain is located near the crankshaft position sensor.
      Filling Procedure
      Reinstall the engine block drains
    3. Close the radiator drain valve,
      1. Install the coolant recovery reservoir. Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL coolant. If Coolant other than DEX-COOL or HAVOLINE DEX-COOL is added to the system the engine coolant will require change sooner; at 50,000 km (30,000 mi) or 24 months.
      2. Slowly add a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water to the radiator until the coolant level is at the base of the radiator fill neck.
      3. Wait for 2 minutes and reinspect the level of the coolant in the radiator. If necessary, add coolant to the radiator until the coolant level is at the base of the radiator fill neck.
      4. Install the radiator cap.Ensure that the radiator cap arrow points toward the radiator overflow tubeImportant: The air bleed valves are brass. Do NOT over-tighten the air bleed valves.

        1. Close the air bleed valve above the coolant pump.
          1. Close the air bleed valve on the thermostat housing.
          2. Fill the coolant reservoir with a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water. Caution: Refer to Radiator Cap Removal Caution in Service Precautions. Important: If the coolant temperature indicator turns ON, turn the engine OFF immediately and allow the engine to cool. Do NOT remove the radiator cap.
          3. Start the engine and allow the engine cooling fan to cycle on and off 3 times. If the low coolant indicator does not turn OFF and the coolant level is above the Full Cold mark on the coolant recovery reservoir, refer to Engine Coolant Temperature Gage Inaccurate or Inoperative.
          4. Turn off the ignition.
          5. Allow the engine to cool.
          6. Ensure that the engine coolant concentration is sufficient.
