Replace the serpentine belt tensioner, with pulley, including the engine mount, on a 1995-1997 Pontiac Sunfire.

Steps

1. Move the coolant reservoir aside

   Disconnect the battery with an 8mm wrench, unclip the reservoir and remove its 10mm bolt.

2. Remove the engine mount

   Support the engine, remove its five 15mm bolts with a socket and extension, pull the mount out, then unclip the lines attached to it.

3. Remove the old tensioner

   Note the belt routing diagram, use a wrench on the tensioner to relieve belt tension and pull it off, then unbolt the tensioner with a 15mm wrench.

4. Install the new tensioner and reassemble

   Bolt the new tensioner in, follow the diagram to route the belt and use the wrench to slip it on, bolt the engine mount back in with the 15mm socket, clip its lines back in, then clip the coolant reservoir back into place.
