Draining the radiator of a 2001 Pontiac Grand Am is an easy process that can be completed in less than a half hour. The coolant in the radiator should be drained and replaced with each tuneup or about every 3 to 6 months to maintain the effectiveness of the fluid in keeping the engine temperature regulated. The radiator system on the 2001 Grand Am is a standard radiator model with the Pontiac line and can be drained from the bottom of the radiator.
Remove the cap from the top of the 2001 Grand Am radiator by lifting the radiator cap lever and turning the cap counterclockwise.
Locate the coolant reservoir overflow tank on the passenger side of the engine compartment and take the cap off the overflow tank.
Locate the drain cock valve on the bottom of the radiator and place a plastic drain pan underneath the drain valve.
Open the drain valve with an open-end wrench and let the coolant drain completely from the radiator.
Find the lower radiator hose that is attached to the bottom of the 2001 Grand Am radiator and unfasten the clamp, using a screwdriver to loosen the screw on the clamp.
Place the drain pan underneath the lower radiator hose at the radiator and slide the hose off the radiator flange, prying it off with a screwdriver to let the remainder of the coolant drain into the pan.
