Open the drain valve on the bottom inside of the radiator, run the engine with the garden hose in the radiator cap, have the heater switched on high temp.  After the water comes out clean, turn off engine and let all water drain out.  Replace with 50/50 mix if distilled water and antifreeze.  Collect old antifreeze as it is very toxic and poisonous.

What is proper method for flushing the radiator and engine in a 1999 Pontiac Montana?


1: Drain coolant system
2: Purchase coolant flush, making sure you have the proper amount for your size of coolant system
3: Pour coolant flush into your radiator, filling the rest with water
4: On the coolant flush bottle it will tell you how long to run your vehicle
5: Once done running, let cool enough to open radiator cap, and drain system COMPLETELY by first draining out of pep **** on radiator, then taking one side of the hoses off the radiator and draining those
6: Put hoses back on and fill system with coolant. When the fluid gets to the top of the fill port on radiator, start vehicle and let run, allowing air to escape the system, and fill as necessary

A diagram of the flushing of a radiator and block of a chevrolet blazer LS 2000


Theres no such thing as a diagram, here are the draining instructions, hope this helps...
  • 1-Place a large drain pan beneath the radiator drain plug. The drain plug is located on the passenger side at the very bottom of the radiator on the engine side.

  • 2-Make sure the engine is cool. Open the hood of the truck and remove the radiator cap.
  • 3-Loosen the drain plug. On the 2000 Blazer, the drain plug is a wing-nut type of plug. Twist it with your fingers until the coolant begins to drain.

  • *To flush the block, once you have drained the radiator, run the engine for a bit untill the temp gauge goes up to normal, then the coolant will have been evacuated from the block. DO NOT leave the engine on, once it reaches normal temp, (this will happen quick) turn off right away, otherwise you'll be forking out a few hundred $$$ to fix the worped heads.
    4-Tighten the drain plug with your fingers once the coolant has drained fully from the radiator. Remove the drain pan and dispose of the used coolant properly.
    Some service stations will take and recycle your used coolant.
    Hope this helps...

    Where is the radiator drain on a 2003 Chevy blazer v6 and do you need a special tool?


    There is a draincock on the bottom of your radiator (probably hidden by the splash gaurd). You can either take the splash guard from the vehicle to drain the radiator, or disconnect the lower radiator hose. Both methods will allow you to drain the radiator.

    Radiator flush


    The drain plug should be located on the drivers side on bottom of radiator. Should be a flat tab that you can use to unscrew it. Or the faster/messier way of doing it, is to pull of lower radiator hose. Alot faster but alot harder to catch coolant to reuse.
