Difficulty: Beginner · About 20 min · Pontiac Grand Prix

Replace the upper radiator hose on a 1997-2008 Pontiac Grand Prix.

Steps

1. Remove the old upper hose

   Unbolt the brace with a 13mm socket, move the coolant bottle hose out of the way, unclamp both ends of the radiator hose with pliers and pull it off, then wipe down the fittings and clean off any corrosion with a wire brush.

2. Install the new upper hose

   Fit the clamps onto the ends of the new hose with pliers, position it on the fittings and slide the clamps down to tighten them, fill the coolant reservoir with the coolant specified in your owner's manual, then reconnect the coolant bottle hose and bolt the brace back down with the 13mm socket.

Check your vehicle’s repair manual for exact specifications and fit.
