Question about 1999 Mitsubishi Diamante
Looking at the front of the engine you should see, from left to right, the PS pump, a tensioner pulley, and the crank pulley.
Loosen the 14mm fixing bolt and the 14mm fixing nut on the tensioner pulley.
On the bottom there is a 14mm adjuster bolt, loosen it to slide the pulley downward. It helps to have a swivel socket to access this bolt.
The belt goes around the outside of all 3 pulleys.
The alternator belt will need to be loosened to get the PS belt on behind it.
Between the Crankshaft pulley and the ac compressor pulley you will see another adjuster. Simply loosen the 14mm nut on the center of the pulley, then loosen the 14mm adjuster bolt sticking out the bottom to slacken the belt enough to slip it off.
Use the same adjusters to tension the belts once installed, and tighten down all fixing nuts/fixing bolts.
Be advised: If you broke your PS belt, you should verify your pump and tensioner pulley are in good shape and spin freely, and were not the cause of belt failure before putting on a new belt!
