Timing belt OEM Toyota or Mitsuboshi

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

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.

Timing belt could also be listed as “Mitsuboshi”. I’ve ran these belts on my 520rwhp jzx100 1jzgte vvti no problems at all.

I only use Mitsuboshi brand timing belts, even on built Subarus.

That’s what mine cost at my local Toyota dealer, my 06 had 70k miles and never had it done and that $1200 for a peace of mind was Money well spent in my opinion

Anytime I’ve done or seen a Toyota timing belt done at the recommended 90k it looks like it has plenty of life left.

I've never seen a Toyota or Lexus have a belt failure. The other components idler(s) and water pump are usually the cause of catastrophic timing failure.

I have a 2001 Lexus LS 430. It had about 215,000 when I got the timing belt replace. It was the original and was starting to crack. If my 21 year old belt made it to 215k and didn’t break yet. Thats when I saw mine was old and cracked.

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.
