I bet if they had used a Mitsuboshi timing belt in the first place it would have lasted much longer.

Pros: would have lasted longer

The only thing I concerned was the timing belt itself. It was a US made MITSOBOSHI instead of Japan made one. But it was perfect fit, didn’t miss timing even by 1 teeth.

Pros: perfect fit, accurate timing

Cons: US made (initial concern)

Vehicle: Toyota Land Cruiser

Had the timing belt replaced last year - didn't find a single crack on the old one despite it being 20 years old. Ditto for the serpentine belt. The dealer's head technician had told me that Mitsu's rubber quality is top notch - on par with Toyota, way better than Nissan's (his words). I didn't believe him until I saw the belts with my own eyes.

Pros: no cracks after 20 years, top notch quality

I bought a Mitsoboshi (not misspelled) from autohauz az a bit ago and it had a more round, but not completely half moon round, tooth profile than I've seen before on Contitech timing belts.

Pros: good rep, big company

Cons: round tooth profile

After just snapping one in my Audi A4 B7, I had to rebuild that entire head. Total pain in the ass. The factory belt lasted 15 years, 175k miles before it let go.

Cons: engine damage, difficult rebuild

He had installed an OEM manufacturer Mitsuboshi timing belt, and it snapped. Apparently it was a knock off. He reinstalled the old belt. I disconnected the injector to the cylinder with a bent valve, and drove it 200 miles home, on 5 cylinders. It actually ran better when I plugged the injector back in, When I got home.

Cons: belt snapped, knock off

Vehicle: Honda
