How do you replace an idler on a Mercury Topaz?

DISCONNECT THE MOTOR MOUNTS ON THE LEFT SIDE, PLACE JACK UNDER OIL PAN, PUT PIECE OF WOOD BETWEEN JACK AND OIL PAN AND RAISE ENGINE. THIS WILL GIVE CLEARANCE BETWEEN FRAME RAIL AND IDLER. REPLACEMENT IDLERS ARE NO LONGER AVAILABLE FROM FORD, SO YOU HAVE TO KNOCK OUT BEARING AND REPLACE IT WITH NEW ONE. BEARINGS ARE COMMON AT MOST JOBBERS FOR LESS THAN 5 BUCKS. REMOVE SERPENTINE BELT REMOVE IDLER BOLT AND PULLEY, REPLACEMENT IS REVERSAL OF THIS. LOWER ENGINE, TIGHTEN MOUNTS AND YOU ARE READY TO GO.
