As the title states, the timing belt broke after about 100 miles total of driving the truck. We were driving on the highway and everything just quit. I just had it recently rebuilt and everything was timed right and everything looked good. ALl the belts I had with the truck looked good. I bought it off a mechanic about a yearish ago. It started right up after the rebuild. I have noticed that the crank sprocket is a little hard to rotate with the socket.

Is there anything that I could have missed while reassembling it? I followed the books and everything.

Is there a specific timing belt I need to order?

Did you install a brand-new timing belt, or just reuse the old one because it looked fine?

i believe the g63b 2.0L 8v sohc is a non interference motor so you should be able to slap a new timing belt on and drive off.

I believe it is as well. I wasn't sure if the cam gear was too tight and there was too much resistance? I can turn it with a wrench and there is some resistance, but I think that is from the springs.

Yeah, cam sprockets typically don't turn freely, more of an uneven "chunky-feeling" resistance to the movement as each cam lobe operates a valve.

And never reinstall a timing belt, no matter the age, mileage, or visual condition. Even if I'd just installed a brand-new belt and then needed to remove it again right away for any reason, I'd still replace it unless I never even tensioned it in the first place.
