Which length belt for 3.0si?

Hi guys,

Finally got around to changing serpentine belt and pulleys and tensioner. The belt I pulled off, which is original, judging by date on it, is a Contitech 6PK1827. All the belts I can find online are 1830 mm in length. Presumably the tensioner is easily able to handle an additional 3 mm, but what do you guys say? Do people just use 1830? RealOEM shows 1827 for my car.

Installed the 1830 and nothing has exploded yet, so that’s good.

Got a p/n handy for the tensioner?

Many thanks. Is INA the OEM supplier?

Removed the original tensioner - it is indeed INA.

Yeah, I’ve understood INA is OEM for lots of BMW pulleys, tensioners, auxiliaries.
