Help with pulleys

Hey I new to change both idler pulleys because they are making a lot of noise. It's not even 2 years I change both and they are shot again, I want some with quality better than stock ones if they are. Thanks

In pulleys, I'm not aware of any that are better than stock .... basically your choice is BMW, OEM, and maybe foreign knock-offs. There's only one idler pulley and two tensioner pulleys.

My tensioner went again after 3 years. It all depends on how you drive, the temperatures (cold and hot alternating climates), etc.

I replaced mine again with OEM INA pulleys.

I just order mine from OEM INA, they look much better built and quality too.

I just replaced mine along with the idler pulleys. Mine were all mechanical versions. I bought mine through Advance Auto (those coupon codes bring the price to just about online prices lol). The parts were all Dayco, but they were stamped with INA . Car runs soooo much quieter now. If your pulleys sound like a skateboard when you free spin them it's time for replacement.

Easy fix and you might as well do both belts while you're there.

Good luck!

It's been 2 year since I changed belts when my pulleys gave out and broke my belt into million pieces.
