The Mods might want to move this to the Tech Section if they see fit, or make a write up after I'm done but anyways here goes....


Monday I was driving home from work and started to hear a weird sound like a Power Steering belt was slipping or something. The Temp guage started to rapidly climb so I pulled over and let it cool. started it back up and temp guage went back to normal but I could hear a faint "rumbling sound". I thought in could be a bad water pump bearing that was temporarily frozen. I cautiously drove the rest of the way home with the heater on with no problems. I pulled the drivers side timing belt cover off and found the smooth side of the belt showing signs of slippage. I ordered the Timing belt, Idler pully, and tensioner pully, off ebay on Tues morning. I had a lifetime warrantee on the Water pump so I called the Auto parts store and made sure they had one in stock for exchange when I got the old one pulled off. The Belt (napa Brand) and Pully/Bearing were all on my doorstep by thursday morning. My plan was to do this on the weekend, but I was lucky enough to get off early Friday so I began the tear down process..Here's the Photo's, please excuse the red Moab mud all over the engine:

First oreder was to remove the Plastic plenum cover, battery with tray, Air box, fan and accessorie belts. The Power Steering pump was dissconnected from the acc. bracket but the Hydraulic lines were left connnected and pump moved out of the way. The hardest part of this is removing the AC pump from drivers side of the engine its connected by (4) 10mm bolts that arent the easiest to get to. Strong hands/forarms and a 1/4" drive ratchet come in handy for this one. Leave the soft lines connected to the pump and move out of the way, bungee cords or twine can come in handy for keeping stuff out of the way. Remove ac pump mounting bracket after pump is out of the way.

Next I removed the big aluminum Accesory bracket, leave the alternator connected, and dont forget to onplug it from the wiring harness and disconnect positive lead.

Here's a shot of the engine with the bracket off:

The next step was to remove the crankshaft pully. There is a special tool available to assist in this and I would highly reccommend you use it if available. It holds the pully stationary while you remove the crankshft bolt. I dont have the tool so I used the Imfamous "electric impact" better known as the starter trick, which involves one person putting a 1/2" breaker bar with socket on the crank bolt, bracing it against the steering box and another person cranking the engine momentarily. This method has broken crank bolts in the past so if you decide to use this technique proceed with caution. It worked for me and the next step was to remove the plastic timing belt cover.

When I removed the cover this fell out:

The Idler pully bearings had exploded. Luckily the timming belt didnt slip any cogs.

That was enough work for a friday afternoon, I'll pull the water pump and replace it. Hopefully I'll have the rest of the truck together and documented before the end of today(Sat)

on an unrelated note, sasquatch was spotted in So Cal next to my Montero yesterday..... <img src="/forums/images/graemlins/lol.gif" alt="" />
