Quick and painless.
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!

It’s not worth the $60 savings if it causes the belt to come off in the middle of the lake. Because the pulley is not the same as the original it causes a misalignment. Over 3700rpm the belt comes off. Luckily I was able to put it back on twice and get back to the slip. Once removed and replaced with an OEm absolutely no problems.
