Fountain of knowledge Aux belt 4PK or 5PK

[EM1L4]

Hey all,

Looking to scratch the collective brain of this forum,

I replaced the alternator on a Suzuki Swift (58 Plate), all was fine until the belt started squeaking, I’ve finally had a look and the Aux belt is FUBAR. on closer inspection I realise the replacement alternator has a 4PK pulley and the rest of the car and belt is 5PK. Explains why the belt is now shagged, my bad…

Question now is do I spend a few hours putting a 5PK pulley on the alternator (awkward to get to) or can I get away with using a 4PK belt on the other 5PK pulleys?

Pitch is the same irrespective of if it’s 4pk or 7pk. Just bung a new 4pk belt on. As long it’s in the right 4 grooves your fine

I have an 09 swift, the belt always squeaks a bit when its damp and all the electrical stuff is on.I've replaced the belt, nice and tight but it still squeaks/squeals.Just got used to it now, turn all the electrical stuff off, give it a rev and its fine.

Thats what I originally said to the Mrs, but it carried on for far to long so I actually had a look and now see all the rubber dust everywhere from it removing the 5th V I don’t recall it squeaking on the old alternator but I wonder if your belt has oil on it or similar?

Mines done it pretty much since I've owned it, maybe 7 or 8 years now.Its had a new belt and still squealed.I think I may have got rid of the noise once when although it was tight I gave it a little more on the tension.I probably should give it a little more now but its one of those things I can live with.Funny that it only does it when its damp, I'm thinking it must be a slight design fault with possibly not enough of a pulley encircled by belt.I think I might also get an odd slight loss of power when its making the noise.
