Engine: B5244: - Aux / serpentine belt help need

BlueRubber · Nov 30th, 2020, 20:21

Looking to change my aux / serpentine belt and tensioner as I'm not 100% sure when they were last changed.

When I look in VIDA it shows two part numbers for the belt:
30731808 & 30731811
1 - How can I tell which one I need?

2 - I was planning to buy an INA tensioner & belt, is that a good choice?

3 - Is there anything else I should change while I am there?

4 - I was going to check the following:
Alternator pulley check

Check other pulleys turn and don't feel rough?
Is that all I need to do?

5 - I assume that I should follow this video rather than SiRobb's video on doing this in the D5?

Apologies in advance for all the questions, a bit nervous about doing this and trying to cover everything!

Can't help re- which belt you need or the difference between the two,but INA are ime a very good reputable make for belts and I believe their kits come with SKF bearings in pulleys/tensioners.Yes I'd feel for roughness/play in other pulleys[water pump etc]while the belt is off it only adds a few seconds to the job and gives a bit of peace of mind.

These are my tips for gasoline engines. Also read in the video description

This american site is pretty good to check the fitment - see the Fitment tab on each item page. You will need the longer belt. The shorter one was used on some XC90 engines that had a 120 bar p/s pump with a smaller pulley. Yours is a 110 bar pump with slightly larger pulley
