Gen 3 Timing Belt

[Prepare.Defend.Lead.]

I recently purchased a 2003 Gen 3 Limited, with 144,000 miles on it, the body and the interior are in excellent condition. I am starting this project by catching up with the maintenance.
I have already done.

Spark Plugs
Wires
Coils
Freewheel Clutch Control Solenoid
Removed the butterfly valves
Inner Tie Rod Steering Boots
Serpentine Belt
Front and Rear Diff Fluid
Transfer Case Fluid

Next up is the timing belt. Any thoughts would be appreciated. I plan on swapping out the crankshaft bolt and the water pump while I'm in there. Is there anything else that I should swap out while thing are pulled apart? Thanks

Gen 3, which timing belt kit and immediate maintainance

Hi Guys, I found my dad another gen 3. He currently has a 2001 XLS with maybe 150k on it, it's starting to need some work. The "new" Montero is a 2002 Limited with 80K that looks to be not religiously maintained but drives excellent and got it at a great price. I noticed if the car sat...

Here you go !


I recommend replacing the crank and cam seals, o-rings and Crankshaft position sensor if you have not done so.

X2 on the sensors and seals. Might also think about replacing the little O-rings on the injectors. Those get brittle and are easy to replace. If you haven’t read it elsewhere, lots of hate on using 3rd party timing belt tensioner. If you can afford it, go for OEM for the tensioner. It might just save your motor.

Another thought, there is a small metal pin that holds the crankshaft gear in time. Don’t mess that up. I accidentally drove that pin into the gear and had to replace the whole thing. Search my username on here and you’ll find a few threads related to engine rebuilds and timing belt jobs. Don’t do what I do, learn from what I’ve done so you don’t make all the same mistakes

Wow! From an excel nerd, I truly thank you for this ChrisCosta416!

I'm 4 months deep on the hunt for a Gen 3, so I love these threads. Always something new to learn.
