Hey y'all

I ordered an idler pulley from amazon:

regarding the product description I thought it will fit in my 2001 V6 4.3 trailblazer with A/C
When I took out the idler pulley that was installed, I realized that they have a slightly different shape and the old one has this Nr. written on it:
0 1 25702W (nothing else)
When I try to find anything regarding this serial No online, I can't find anything.
Do you guys think the product I ordered can be installed or do you know where I can get a pulley that will fit?

Thanks

 

As far as I know, the difference lays in an outer diameter. If the diameter match, then You got the correct one.

 

As Mike said, just make sure the diameter is correct. Maybe measure the back of the pulley to a feature on the engine and compare that to the new part as well?

I just replaced with pulley bearing with an 302ff bearing. $4 or so.

 

I dont think you have the right one. The center hole for the nut looks too small

 

 

 

Exactly. Your perceptivity is better than mine.

 

Thank you guys!

 

I have repaired my idler pulleys two times. It's a simple standard bearing which can be easily pressed out and a new one in. Just make sure about the position of the bearing.
