Question about 1999 Chevrolet 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.

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.
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.
