The best way to drain the coolant in my opinion, is to remove the bottom hose from the radiator. this also drains coolant from the engine. although not all of it. or you can locate the petcock somewhere along the bottom of the radiator and drain it that way. in both cases, have a large enough container to catch the coolant. removing the bottom hose can be messy but it's much faster.

Where is the coolant drain plug


On the bottom of the radiator. There will be a little plastic valve that looks like a butterfly. Spin this to loosen it, and it will let coolant flow out.

How to flush coolant on 2004 grand prix


  • Move your badass w-body (a.k.a. Pontiac Grand Prix) to a level area and set the parking brake. Pop the hood and touch the radiator. If it's warm let it cool before you continue.
  • Twist the radiator cap one full turn (Remember to be careful because even when radiators are cool they can still erupt coolant)
  • Place any type of container (bucket [but has to be able to hold 2 gallons]) underneath the radiator and blow the drain plug. (The drain plug on your Grand Prix is on the driver's side bottom of the radiator facing the engine.)
  • Loosen the drain plug and let the old coolant to drain completely. (You may need a wrench to loosen the drain plug)
  • Dispose the old coolant in a sealable container (The coolant is very toxic to people and pets, so you gotta be careful)
  • Shut the radiator drain plug and fill the radiator with water.
  • Run car for a little bit and repeat the process again. (Let car cool, and drain water)
  • Close the drain plug and fill the radiator with fresh coolant until it's about an inch from overflowing. (DO NOT USE ORANGE DEX COOLANT IT IS HARMFUL FOR YOUR HEADGAKETS) You will need 3 gallons of coolant (SE, GT, GT1, GT2, GTP, GTP Comp G.) and 4 for the GXP model. Be sure to check the drain plug for any leakage.
  • Start your car and turn the heating system to high. Allow the car to keep running until the cooling fan turns on twice. After that happens, switch off the engine and check the coolant level. If it went down, add more coolant. If not, put the radiator cap back on and close the hood.

    Where is the drain plug for the radiator


    Should be a drain **** at the bottom of the radiator that unscrews out. It looks like a wing nut has been welded to a bolt on the end of it. Another way to do this is just pull off the bottom hose.

    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.

    Where is the engine coolant drain bolt on a 2003 2azfe camry? i found the radiator drain but can't find the engine drain plug-a photo would be great


    The textbook method is to remove the drain plug on the bottom of the radiator.

    Most drain plug is make of inexpensive nylon/plastic and it may fall apart while you turn it.

    The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.

    Drain the coolant onto a large drain pan and recycle the coolant

    How do I flush the coolant on the 2002 tundra V6?


    PROCEDURE TO FLUSH
    • Park the Toyota Tundra on a level surface and set the parking brake. Then, with the engine off, touch the radiator to gauge its temperature. If the radiator is still warm, allow it to cool off before you start next step.
    • Twist the radiator cap one full turn, pause for a few seconds and then fully remove the cap. You want to pause to relieve any internal pressure inside the radiator. Opening a pressurized or hot radiator can cause it to spew hot coolant and burn anyone it comes into contact with.
    • Position a bucket or tray with a two-gallon capacity underneath the radiator, below the drain plug. To access the drain plug, you may have to remove the plastic engine undercover, which should be on the driver's side of the Toyota Tundra's radiator. Use a socket wrench to open the plug.
    • Open the drain plug and allow the existing coolant to drain completely into the bucket. Once complete, pour the old coolant into a sealable container for proper disposal.
    • Put the drain bucket back under the radiator and close the drain plug. Then, fill the radiator with distilled water. Next, open the drain plug to let the water flow into the bucket. Replicate this procedure until the water runs debris free out the radiator.
    • Replace the radiator drain plug and pour fresh coolant into the radiator until it's within an inch of overflowing. With the Toyota Tundra, you need to use the same coolant that came with the truck. Most likely, it is Toyota Long Life red coolant, but consult the owner's manual to be sure.
    • Start the engine of the Tundra and turn the heating fan to high. Allow it to run until the cooling fan turns on two separate times.
    • Switch the Toyato Tundra off and check the coolant level. If it is lower than before, add more coolant. If not, put the radiator cap back on and close the hood.
    1. TIPS
    • You will need 2 gallons of coolant for the four-valve Toyota Tundra and 3 gallons of coolant for the six-valve model.
    • Using tap water from a hose is an alternative to flushing with distilled water, but tap water can leave sediments behind that can damage your coolant system
    WARNING
    • Because coolant is extremely toxic to people and pets, it's imperative that you dispose of the old coolant properly.

    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.

    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.
