Title: Noise from aux belt
Post by: Syco on April 20, 2021, 14:32:07: Hi, got a 2015 G4LC i30, It's been making a horrible noise from the aux belt. Running the car briefly with the belt off and the noise is gone. I took the water pump off and it's fine and replaced the idler puller and noise is still there. Cars only got 50k on it but thinking it might be the alternator.
Whats got me puzzled is it's a 7 vee pulley and belt, everything I see online is for a 6 or 5 vee belt.
Am I missing something? Is this unique as it's right on the model transition?
Any one replace the alternator bearings on one of these?
TIA

Paste your vin into :link: PartSouq Auto Parts Around the World (https://partsouq.com/) and see if there's any enlightenment there, regarding the vee configuration.

Once upon a time you could get "belt feed" spray to recondition slipping belts.
