    I don,t even have a drain plug, on my radiator. Did it the old fashioned way, pulled lower hose off.

    I have a 2003. I found the plug, but it looks like it might take a special tool to open. Where is the "lower" hose?

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 drain plug on a 2003 chevy blazer

    The oil drain plug is located on the bottom of the oil pan.
    The radiator drain is on the bottom passangers side of the radiator.
    The transmission drain plug is in the trans oil pan , or you may have to drain by releasing the tension on the pan bolts... in which case you will likely need to replace the transmission pan gasket to reseal it.

    Need to know how to drain radiator fluid on a 05 chevy blazer?

    There should be a drain plug on the passenger side of the radiator. If there is no drain plug and both hoses are at the top of the radiator you can pull the lines to the transmission. Adjust the flow coming out by taking off and putting on the radiator cap. Just make sure to reconnect the lines before you refill the radiator.

    How do I drain and replace the engine coolant for a chevy Blazer?

    You'll want to remove the radiator cap. On that tank, on the bottom toward the engine is a drain to unscrew. You might want to spray some WD-40 on the drain plug, to help get it unscrewed.

    How do i drain the radiator and flush out on a 1999 chevy blazer?

    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.
