It should be located on the bottom of the radiator by the bottom radiator hose, if not there chk. other side of the radiator at the bottom its just a plastic button that you screw out, but it does not come all the way out.

    Anyone REALLY know where the drain plug is. Already went through the hassle of remloving the guard, and there aint nothing there for a drain plug.

    The plastic with two prongs on the outside end CAN BE removed (just don't throw the plug with the engine coolant) ha The drain is on the driver side far right of the radiator. Lift the radiator flap to see where the hoses go. I did have to remove the bottom motor shroud behind the bumper, (Needed under there anyway)

Water in floorboard front and back

My 2002 Bonneville had water problems soaking carpet and trunk area. I had it to the dealer twice, it was to expensive to go back a third time. I found 3 of the four drain tube disconnected midway down the roof piller posts. Probably from when the mechanic used air pressure to dislodge the plug. The front two were very challenging to get at to push the drain tubes back onto the connector. Why would they put the drain tube connection at such a poor location for repair is beyond me. The good news is no more water leaks since the drain tubes were reconnected.

Petcock location for pontiac

Hi, those things are pretty much a thing of the past with the aluminum radiator cores and now they crimp composite plastic caps on the tube ends and there is really no solid place the put a drain. Now the common practice though not the prettiest but the only way is to pull the lower radiator hose off to drain the system. Garages of course now use pumps that they slip down into the radiators to do this job. Simple at home cheat is to use a gas pump that you squeeze a bulb to get a siphon going and drain it that way, not as messy.

I would say, if you have worked on older cars you can handle pulling the rad and replacing the drain assembly,just watch tightening parts into the plastic rad tank.If the rad looks grungy at all when you get it out,replace it.
