SOURCE: where on the radiator is the drain petcock 2004

Some models do not have a petcock, pulling the lower radiator hose will suffice in drainage. I suspect you know what you are doing since you have the correct nomenclature. Use extreme caution during this type of draining procedure when coolant is hot. If it is not on the lower left or right corners of radiator side facing engine, it is not equipped with a drain valve.

How do I locate the radiator drain plug ON GMC ENVOY 2002?

You may have to take a plastic shield off that is under the engine compartment to get a good look at the radiator. The drain plug or petcock should be facing backward at the bottom of the radiator, usually near a bottom corner of the radiator (ie not in the middle bottom)

How do i find drain plug on the radiator for a 1998 gmc sierra truck

Not all radiators have drain plugs, if it does, it is on the inside bottom, just a petcock valve. Most of the time you just pull the hose and dump into a pan or flat bucket. Hope this helps.
