Quiet and smooth in Engines & Engine Parts

Replaced the original almost 20 year old tensioner that was very noisy and loose. I didn't realize how worn the old one was until I compared it to the new one. Now it's very quiet and smooth. Yes, it's expensive, but it does the job right the first time.

Pros
  • Engines & Engine Parts
Cons
  • Out of fashion

Believe me ! Take it!

Non original bullshit. I've noticed my headlights are a lot brighter and I have more power when I paid the extra money for the OEM. Saturns are very picky about details. Pay a little more now and be sure you're better off.

Pros
  • Control parts
Cons
  • Can't remember

Failed at 600 miles with new belt

Worked great after replacing my cheap no name 40,000 mile tensioner that had a knocking problem. However, one day it accidentally failed without warning after about 600 miles of use. It actually rattles worse than my old one. I put a new belt on when I installed it. Not sure if I got a random lemon but not happy at all.

Pros
  • Engine Parts
Cons
  • High Price

Stop rattling! Fits perfectly. Easy installation.

Perfect fit. This repair is not difficult if you loosen the upper engine mount bolts and raise the engine slightly. I did this and it took less than an hour to swap it out (which is remarkable for me - usually this becomes a weekend nightmare for me, but I still do it). The screws shown are not included in the kit, but the original screws must be used in any case. It also doesn't have the yellow and blue plastic stuff, whatever they are - I hope I didn't need them. I don't have any yellow and…

Pros
  • Spare parts
Cons
  • poorly thought out
