Tip

Flush the coolant on the 2002 tundra


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.
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.

  • 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)

  • 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.

How to replace coolant for nissan altima 2006


Park the Nissan Altima on a flat surface and set the parking brake. Next, open the hood and check the external temperature of the radiator. If the radiator is warm to the touch, wait for the radiator to cool before you continue.

Twist the radiator cap one turn to relieve any pressure. Step back from the radiator and allow a few seconds to pass, and then completely remove the radiator cap.

Place a bucket or tray with at least a 2-gallon capacity underneath the radiator and below the drain plug. The drain plug on a Nissan Altima is on the passenger side bottom of the radiator.

Loosen the drain plug and let the old coolant drain completely into the bucket. Take care while loosening the drain plug, because it's plastic and can be brittle. Pour the old coolant into a sealable container for proper disposal later and put the bucket back under the drain plug opening.

Close the drain plug and pour distilled water into the radiator until it's full. Then, open the drain plug and let the water flow into the bucket. Keep repeating this procedure until the water runs clear and debris free into the bucket. You will need at least 3 gallons of distilled water.

Make sure to tighten the drain plug and fill the radiator with fresh coolant. Refill the radiator to within an inch of it overflowing. Check the drain plug and hoses for any possible leaks.

Start the Nissan Altima and turn the heater to the high setting. Let it run for about 10 minutes and shut the engine off. Check the coolant level and refill, if necessary. Finally, put the radiator cap on and close the hood.

Draining cooling system 2001 olds bravada


There is a drain plug on the radiator on the divers side, inside at the bottom. Note: most of the time when the plug is removed the O-ring get's damaged and needs to be replaced since it sticks to the radiator. Most of the time it's quicker and easier to disconnect the lower radiator hose on the passenger side and let it drain there. Most of the newer radiator don't even have a drain plug and if you want a drain plug,you'll have to drill a hole where the drain plug should be and place one there. The drain plug is around $4.99 at most Auto Parts store. Good luck and hope this helps.
