The textbook method is to remove the drain plug on the bottom of the radiator.

Most drain plug ismake of inexpensive nylon/plastic and it may fall apart while you turn it.

The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.

Drain the coolant onto a large drain pan and recycle the coolant

It should be there. Just look hard under the radiator back-side wall, or directly under the radiator.

I need to locate radiator drain plug in a 2003 gmc savana


Loosen the lower radiator hose, most engine cooling systems hold about 2 Gallons or more. Just precaution have at least a 3 gallon catch pan/bucket that will fit underneath the van.

2003 GMC Savana Van. The resevoir is full. The radiator is full, yet rusty looking water. Ran hot, thermostat redlined. Let engine cool. Made it a few more miles. Mechanic wants to do water pump,...


Idea is simple, go to a actual radiator shop to see water is circulating , this is a clogged radiator/ or stuck thermostat or water pump. Master cylinder and serpentine has Nothing to do with your issue.

My 1999 gmc savana van turns over but does not


could be a bad fuel pump, or fuel pump relay. they are having problems(a lot) with the ethanol in the gas on GM products.Fuel pumps sales are through the roof at parts house on GM's. Have a pressure check on your fuel system. That is probably it. Add a can of Seafoam to your fuel every 3000 miles to alleviate this problem.

Gmc savana van will stop running while driving or start sputterin


It could be a clogged fuel filter or a bad fuel pump. Also try replacing the spark plugs and spark plug wires and having the timing checked. Good luck.
