there may not be one if there is is it on the bottom side and if it is not you candrain it by removing the bottom rad hose

The 1999 Pontiac Grand Am does not have a radiator drain valve. To drain the radiator, remove the lower radiator hose. The engine should be cold and the water fill cap removed for venting. I have a 2000 Pontiac Grand AM and radiator drain cock is located at the lower/front (not bottom) at the curbside of the radiator, you will need a hex key to back out petcock. .

The radiator petcock drain on a 1999 Pontiac Bonneville is on the bottom of the radiator. Look for a small black plug that looks like the plug found on a thermos or cooler.

Either on the bottom or on the back side of the radiator toward the bottom

You don't have a cap on the radiator. The cap is located directly on the coolant bottle

Drain all the coolant from the radiator. Disconnect the upper radiator hose from the engine. Remove the aluminum thermostat housing. Should be held in place with 2 bolts. There you will find the thermostat.
