I have a 2000 Honda Passport 4x4 w/ a V6. My serpentine belt broke while I was making a 150 mi trip out of town. My friend did me a favor by putting a new one on with a new tensioner as well. However, I didn't have my repaire manual with me at the time and I couldnt tell you if he did it right or not. I believe it to be a NOT though. My book doesnt have a diagram could you please help me out alon with repair steps?

SOURCE: How to get the timing belt off a 97 Honda Passport?

Ok this is pretty simple first of all this vehicle has a hydraulic tensioner so will nee to loose the two bolts that holds the hyraulic tenisor and remove tensioner completely and belt will become loose and can be removed. Its recommended that you change this tensioner when you do a timing belt job at about 60,00 miles. However if you choose to re-use tension it can be compressed(pushed back in with a bench vise and can be held in place for installion by a very skinny allen key of a wire type brake clip or something of that sort. Here is a diagram of your timing marks, conatct if you need more help Good Luck and thanks for using

14 or 15mm socket to release tension. Use socket with leverage bar push/pull towards driver side. Will notice tension releasing, pull belt. Use 5/16 allen wrench for bolt in center, 12 mm socket for mounting bolt. Remove bolts, remove tensioner.
