### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Quick and painless.
  

*by J***Y on Reviewed in the United States on August 30, 2023*

When the power steering pump quit working on my boat I was shocked to find that the idler pulley had broken and caused the serpentine belt to come off. Thankfully I was able to find this new pulley on Amazon and it was delivered to my home in just 3 days. The boat is fixed and I'm back on the water having fun at Table Rock Lake! Thank you!
