W169 pulleys

[Martin blackett]

Afternoon all
W169 A150 2007
With engine coming out soon I read it’s recommended to change water pump and the pulleys to prevent future failure though car only got 76000 miles on
Having trouble finding the pulleys. Lots of different ones online. Some show 3 smooth ones. Some show 2 smooth and one ribbed.
does anyone know the names or part no of the ones to replace.
thanks

The original was ribbed. I replaced the the whole assembly with INA (534 0338 10). It is says it's for v-ribbed belt, but I think all three pulleys were smooth. The noise settled down once the new belt 'bedded' in.

Your A150:

534 0431 10 - without stop-start function

534 0446 10 - with stop-start function.
