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.

Can I replace the radiator on 2007 Impala without removing AC coolant hoses? If not, how do I remove and replace the AC coolant?


It is NOT necessary to remove the "A/C Radiator" (condenser) to replace the radiator. The condenser is mounted in FRONT of the radiator and the radiator is removed from the rear.

  • Drain the coolant from the radiator.
  • CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Always drain coolant into a sealable container.
  • Remove the engine mount strut. Some technicians will disconnect just one and swing the strut out of the way. In this case, loosen the through bolts to prevent shearing the rubber bushings when the strut is moved out of the way for radiator removal. In some cases, it is best to remove the strut and its mounting bracket completely.
  • Separate the cooling fan harness connector from the engine harness.
  • Separate the low coolant level module harness connector at the module.
  • Disconnect the radiator hoses.
  • Remove the cooling fan assembly from the vehicle.
  • Disconnect the automatic transaxle cooling lines from the radiator
  • There should be two small retaining brackets at both ends of the radiator that are removed.
  • Carefully lift the radiator up and out of the vehicle. Note that the bottom should have locating pins on each end which should fit into grommet-like rubber mounts at installation.

    What is new with the 2008 Malibu cooling system, how do you drain and fill the coolant?


    Your Malibu is too new to change the coolant already The coolant is good for 5 years or 150.000 miles, which ever comes first. If oyu are going to replace the coolant, make sure it's the orange coolant and premixed 50/50 water/coolant before refilling the radiator.

    To drain the coolant, just disconnect the lower radiator hose. most radiators now don't have a drain plug like the old days. The issue was that the drain plug was breaking since it's plastic or the O rings would break causing fluid to leak from the radiator.

    once the radiator is drained, simple reattached the lower radiator hose and refill the system. The other way would be to run the engine till the thermostat opens up and the rest of the coolant in the engine block will make it's way out, but at most you should be fine on to replacing the coolant at the radiator only and then run the engine to ensure you have got all the air out of the system.

    Just make sure you replace the radiator cap first before you shut the engine down. It you do shut the engine down first before you place the cap back on, the coolant will blow out.

    Thank you for using fixy and be safe.

    2001 sable where is the radiator drain?


    The radiator drain is going to be on the driver's side along the bottom of the radiator. Best is to remove the lower radiator hose to drain the coolant. Common for the plastic drain plug to break when trying to remove causing you more work and to go out and locate a replacement drain plug. That's why 99% of garages will drain the coolant from the lower radiator hose.
    Thank you for using Fixya and 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 change/flush coolant on a 2003 jetta


    Slap on those vinyl gloves because the ethylene glycol in antifreeze can cause skin damage - however we recommend this because the antifreeze feels like engine oil.With your catch pan in place, remove the radiator drain plug and collect all old coolant. Immediately dispose of the coolant as required by environmental laws - if you are to surrender the old coolant at a waste management facility, be sure you use containers which can be properly sealed to avoid spillage, etc.To expedite the draining process, remove your radiator fill cap to allow air to enter the system.
    Also be sure to remove all coolant from your radiator reservoir. We suggest you use the gravity siphon trick - just be sure not to ingest any coolant.

    Watch the old coolant as it exits the system - this will give you a good idea of your vehicle's cooling system condition.If you see metal flakes, oily surface, white flakes, etc .. you can make a diagnosis of your engine's coolant system.
    Essentially, if you see anything but coolant and some very minor debris, it can indicate the early signs of cooling system failure.When all coolant has been drained from the radiator, replace the radiator drain plug and then fill the system with plain tap water to dilute remaining antifreeze in the engine block.
    With the cooling system refilled with tap water, replace the radiator fill cap and run the engine allowing it to reach operating temperature.When the engine's cooling fan turns on, it is an indication that the vehicle's thermostat has opened, allowing the freshly added water to circulate through the engine thus diluting the remaining coolant. Allow the engine to run for a few minutes before shutting it off.
    At this point, you can either wait until the engine cools off, or take fate in your own hands and continue the flushing process.Repeat the draining process being sure to once again collect and dispose of all waste coolant.
    At this point, if you have opted to purchase a radiator flush kit, you should refill the cooling system with tap water and add the caustic fluid as directed.
    Run the engine for as long as the radiator flush kit calls for (usually less than 10 minutes).

    Once again, drain the cooling system, collecting all waste fluid. This is the last time you will be required to collect engine coolant during this process.Now that the cooling system is empty, replace the radiator drain plug and refill the cooling system with distilled water only. The reason that you should only use distilled water at this point is to avoid mineral deposits which will deteriorate your cooling system over time.
    Once the cooling system has been completely filled, start the engine to allow the water to circulate. Once again remove the radiator drain plug. As the engine runs, pour fresh distilled water into the radiator fill hole at the same rate that it exits the system.Continue this process until the water being drained from the radiator appears to be clear and free of debris. Once you are satisfied with the drain water's appearance, stop the engine and allow all remaining water to drain out.Replace the radiator drain plug and prepare to mix your distilled water and coolant.
    Be sure to mix your coolant to the ratio recommended by your manufacturer. In most cases, the ratio is 50% distilled water and 50% coolant.
    As a tip, mix the coolant and water in a third container being sure to observe the proper ratio.As you mix your water and coolant, use your hydrometer to measure the specific gravity - this will give you a good idea of whether or not you are mixing the coolant and water properly.
    Once you have mixed enough coolant and water to fill your engine's coolant system entirely, grab a funnel and place it in the radiator fill hole.Fill your radiator at a rate of no more than:
    { 1 L/min. \ 1.1 US qt./min. \ 0.9 Imp. qt./min. }.
    Continue the filling process until the coolant reaches the bottom of the fill neck. Now fill the radiator reservoir to the full mark.
    With the radiator fill cap still off, start the car and allow it to idle. As the engine runs, continue to add coolant as air escapes the engine and cooling system.As you top up the radiator, be sure to "burp" the cooling system by firmly squeezing the radiator hoses (both upper and lower). Continue to squeeze and release the hoses to help push any errant air bubbles out of the system.
    Once you are unable to fill the radiator any further, replace the radiator fill cap and stop the engine - you are finished.

    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.
