Place a drain pan under the petcock.
Slowly turn the petcock CCW
Be careful to avoid contact with the flow if the car is hot
Open the petcock several turns until the flow is constant.
Remove the radiator cap to allow air into the radiator
once flow has stopped, close the petcock.

Is there anything more we can help you with?

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.

    How to fill radiator fluid in 2003 suburban 2500

    I generally have stopped even looking for the drain...half of them don't work right even when you do find them. Far easier and faster is to remove the lower hose. If you have a closed system with no cap on the radiator then fill through the reservoir, otherwise fill through the radiator and add to bottle after you are finished. Run the heat on high while filling and wait for thermostat to open and level to drop before final fill.
