Belt Tensioner for the Yaris - Toyota Yaris Forums

This seems like such a nice hack that I am giving this a try, current part numbers that I just ordered are

163810T020 1 $ 9.78 BAR, FAN BELT ADJUSTING
163850T020 1 $ 2.54 Alternator Bracket

While I was ordering parts from Toyota I ordered new upper and lower radiator hoses. My very first car (1968 Fiat 850) taught me to replace hoses BEFORE they break and it's hard for me to accept that modern car parts last as long as they do!! Maybe the Fiat hoses had never been replaced but the ones in the Yaris seem as good now as the day we took the car home. I think replacing them now means I will never have to do it again.

Today I took the serpentine belt out and tried to pull the crankshaft pulley to put the stock one back in (I've had the alloy MicroImage pulley in there for 10 years or so) to try to silence the belt. Could not get the bolt loose on the pulley so I gave up and treated the belt with conditioner spray and put it back in. It's quiet -- for now.

I watched 5 videos on how to remove the crank pulley bolt. But I actually like the MI pulley and I'd rather have the belt tensioner from the 1.8 engine added. (Toyota says it fits 44 cars or something like that... all the XD, Corolla, Matrix models)

The squeaky belt is such a common problem with the Yaris. That and the wheel covers falling off. :-) Ours are zip tied.
