90 GrandAm where to drain coolant?

Look for the petcock on the side of the driverside radiator tank or the very bottom of the tank.

Removing the lower hose is a quicker method for most people.

There are also drain plugs on the side of the block. Typically they have a square hex on the head.

Remove & clean out the over flow bottle too.

Good Luck.
