Hi,, yeah you just turn it out, right to tighten, left to slacken, remember to remove your cap and leave a hose of running water flowing through the radiator to help wash out all the old stuff.

PS.. IF cant find the radiator drain plug, remove the button radiator hose..

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.

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.

HOW TO DRAIN COOLANT FROM MY 2004 6.4 ENGINE MOUNTAINEER


Welcome to Fixya

Here's the procedure on how to drain the coolant from your radiator.


1. Prepare what you need. To make the process easier, it would be wise to have everything you need before you begin:

Pair of latex gloves.
Screwdriver or wrench.
Rags.
Radiator Flush.
Coolant.
Funnel.
Radiator cap.
Draining pan.

2. Place your car on an elevated ramp. If you don't have one, you can use a lifter to do the job. This is usually stashed in your car's compartment in the back. Positioning your car in an elevated position will make the draining process easier. Keep in mind that though that despite your car being in an elevated position it should still be in a level or flat position.
3. Make very certain that your engine has sufficiently cooled. Not warm to the touch but really, really cool. This is a safety measure to avoid your skin from being burned or scalded. Pressurized contents of the radiator will most likely shoot up in the air if you insist on opening the cap while the engine is still hot. Ergo, not a good idea.
4. Look for the radiator plug. Now's the time to wear your latex gloves because you are ready to begin the draining process. Feel the radiator plug underneath your car.
5. Take the draining pan. Place it directly underneath the radiator plug.
6. Tug the radiator plug loose. You will then see that the coolant is now draining into the pan. Once the coolant is collected in the pan, do not dispose of it as you would dirty water. Anti-freeze is bad for the environment. Keep within environmental laws and collect the liquid refuse in a sealed bottle and turn it over to the proper waste management venue. Keep in mind that Anti-Freeze is harmful to your skin so make sure none of the liquid refuse touches your skin.
7. Observe the consistency of the liquid refuse. If you see metal flakes and other tiny debris, this is a clear indication that your cooling system might need the hand of a professional.
8. Proceed to remove the radiator cap. This allows the air to circulate freely into the radiator tubes and helps speed along the draining process.
9. Check to see if the radiator cap needs replacing. Part of the reason why your radiator needs draining is that sediments and dirt coming from the cap directly mixes in with the Anti-Freeze and water in your radiator. If your radiator cap clearly shows wear, tear, and dry rot, replace it with a new one, pronto.
10. Tighten the radiator plug. After the initial draining process, tighten the radiator plug then fill the radiator with water to shake loose remaining Anti-Freeze in the radiator tubes.
11. Replace the radiator cap. Once you are done filling the radiator with water, replace the radiator cap.
12. Turn on the engine. This allows the remaining Anti-Freeze to be shaken off your radiator. Allow the engine to run for five minutes.
13. Turn the car's engine off and allow it to cool.
14. Repeat the flushing process until the water runs clear. Use the flushing agent this time to make sure your radiator is truly clean. You will know it's over when the water runs clear.
15. Pour in the new coolant. You may have done this many times over but it still always pays to read the instructions of the coolant product before proceeding. The rule of thumb is 50/50 which means 50% distilled water and 50% coolant.
16. Tighten the radiator cap.

Where is the radiator bolt located, to drain the water out of the radiator


should be at the bottom of the rad with a little hose coming from it .(the hose points down and goes nowhere just ther to help drain) if you cant find it you can also pull the bottom rad hose off and drain it that way.

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.

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.

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 do you flush out the radiator?


You merely start the engine: loosen the radiator drain-valve, radiator-cap, and refill radiator with water as the engine runs(don't allow the engine run to without water in it). Repeat this for as long as thirty minutes or so until only fresh water comes out the drain-hole. Finally, refill radiator with new anti-freeze. You are done! (or buy a radiator-flush from autoparts store and follow direction written on it). (antifreeze are toxic to our environment)
