Perfect fit for my car

I recently installed this tensioner on my car and it has improved the performance significantly. According to my experience it is a perfect fit and has eliminated the annoying squeaking sound from my engine. The material used is of high quality and seems durable. However, the installation process was slightly challenging as it required some technical knowledge. .

Pros
  • Perfect fit, improved performance, high-quality material, durability
Cons
  • Installation process requires technical knowledge

You may need a shorter screw!

Not really a review, I just installed it yesterday 26th October just FYI. If you are replacing an aftermarket idler, you will need a shorter bolt. If you use the same bolt, there is a risk of damaging the timing cover if you try to secure the tensioner by unscrewing the bolt all the way. The correct screw is an M10 x 1.50 x 50mm shoulder screw, $3.39 at your local ACE store. I wouldn't recommend using a stack of washers unless necessary.

Pros
  • Helps keep the drive belt at the correct tension so it works properly
Cons
  • Not automatic
