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...

    My 2001 chevy blazer stalls periodically when idle. also the temperature gauge shoots up to 260 F very quickly even though th coolant tank is full and when i stop the radiator does not fell warm or hot.

    Check the thermostat to make sure the coolant is flowing through the system. If the thermostat is bad, then the truck coolant will heat very quickly. A thermostat may need to be replaced.

    Dear Sir, I need help to fix engine over heating of my 1997 chevy blazer. For your additional information the engine is not over heated during running whenever I turn on the air conditioning. Thank...

    Many things can be leading to an overheating issue.

    Is your cooling system full of coolant and is it still good. I simple gauge can be bought to test your coolant condition.

    Is the fan moving when running, if it's electric check the relays.

    Another odd thing may be your thermostat is not opening.

    Check things things and get back with me if this dose not solve your issue.

    Good luck.
