2ZZ belt tensioner replacement

Post by ZZvroom » Sun May 02, 2021 2:05 pm

So my hunt for the grumbling bearing continues. When we could not get the tensioner loose to get the belt off, the job morphed into "First replace the tensioner, then.."

First was seeking a source. The only explicit callout to the 2ZZ I found was the Dayco 89733. They were out of stock everywhere I checked. A friend of a friend races 2ZZ's so I asked him if I should get Toyota part, or an aftermarket. At his advice I went to PartsGeek.com and got the Metrex Part #: W0133-1894695 and of course the next day, RockAuto got the Dayco back in stock but with a $20+ price increase.

Two questions:
  1. As for installation, the GM manual says zero about removing motor mounts & jacking the engine up. The writeup I found here is on the 1ZZ, it goes into detail on such; has anyone done a 2ZZ?
  2. The PartsGeek page https://www.partsgeek.com/catalog/2003/ ... _assembly gives stern warnings about installing the tensioner, but they are cut off.
So I ask if anyone has installed a 2ZZ tensioner, and/or knows what Metrex is talking about re: tensioning the tensioner?

A friend found https://youtu.be/abxTekwidY8 which is fair warning on the job's issues.
