Is someone able to give me the correct part numbers for all three drive belts for my S2 Stagea (aircon, alternator, power steering)

Recently as part of my 100,000k service I bought a set of drive belts. The local gates dealer supplied me with

4PK835R

4K865R

4PK925R

(I ordered gates racing belts)

When my mechanic did the service he said they didn't fit and the belts on it are at the end of the adjustment. The belts on it currently he said are

4PK865

4PK890

4PK910

I had a quick look on just jap and the numbers they list are

3PK840

4PK855

4PK915

Which are the correct numbers? Please help, no searching is coming up with anything lol

The 4 stands for 4 ridges/ribs. The last numbers stand for the circumference.

If the mechanic said to get 10mm shorter

4PK865 = 4PK855

4PK890 = 4PK880

4PK910 = 4PK900

Mine were replaced a while ago. I just checked them and they are the same as what the mechanic told you you have on your car.

I just noticed something too ( see attached pic) - On the Alternator/Waterpump Belt (890) I am only using up less than 10mm of the adjustment and have a shitload to go. A 4PK880 would be a bitch to put on.I would say your mech. wants 10mm shorter because the current ones are stretched. That's just what happens over time.

Basically, Do what KiwiRS4T said :)

Yeah that's why the mechanic said its near the end of the adjustment. The belt shop gave me a 4PK925R to fit where a 4PK910 should go so he couldnt adjust it enought to fit.

It does seem that the belts currently on the car are the ones I need and are the standard stagea length because they're the same as what's on other peoples stagea's
