It will be on the bottom, probably on the drivers side, I think. it won't look like a regular plug, it looks like a handle you turn.
It is that drain plug looking thing at the bottom left of the radiator.
The drain plug is at the bottom passenger side of the radiator. It takes a 1/4 inch extension to fit into the head to turn it.
The plug should be beside of the bottom radiator hose, and screws out. If you have the model without the plug then the bottom radiator hose has to be removed to allow the coolant to drain.
Should be a plug at the bottom or rear of radiator or remove the lower hose
usually the drain plug is located on the right side of the radiator it could be on the side or under the radiator if you still dont find one you can remove one of the water hose but that wont drain as much as the drain plug also known as cockpit
its on the left hand side of the radiator but not very easy to get to My apology, it is a 1996 S10 Chevy Blazer instead of a 1999 Chevy Blazer. I need to see a picture or more detail of where the drain plug is located on the left side of the radiator. I have searched and searched and cannot find anything to drain with. Thanks, Linel
Assuming you are asking about the radiator coolant drain, it should be on the passenger side under the lower radiator hose. It should take a 1/4" square drive to open it.
It is located just below the lower radiator hose.
Replace the drain plug gasket and don't over tighten it.
Look at the bottom or rear lower section of radiator
To drain the oil on a 1991 Chevy S10 Blazer, located the oil pan drain plug. Use a wrench to remove the plug and the oil will flow into the receptacle you have provided.
The wrench size should be 15mm.
