Ive just replaced the belt on the 90 with a new one, as the old one was starting so show signs of age...
Fitted a new britpart one and now it squeals like f*ck....
Sounds god awful. Put the old one back on, and its now perfect again.
That will be going back on monday...
Does anyone know the part number of a genuine one?
Upon taking the old belt off, the water pump bearings are starting to get a little rough :( next job to add the to the list!
According to my lists there's only two belts, ERR3287 to fit when alternator pulley is 62mm diameter up to chassis number 16L25164, and ERR5911 when alternator pulley is only 49mm diameter from chassis number 16L25165.

The genuine belts that cure the noise are PQS000040 (LATE) and PQS000030 (EARLY) These are made by Gates
I tried one of the supposedly "quiet" belts PQS000040 (=A324 from the local LR dealer) and it made no difference. Colin

Then perhaps your noise is something else.
Water pump bearings is my bet.
Hang on Mark, the new one will be tighter than the old one, i know it's a long shot, but get that wtaer pump done quick mate.
I'd already changed the waterpump twice - the first time for a Britpart item that lasted 1500 miles before the pulley ended up with about an inch of play, a genuine part solved that one. The noise turned out to be the bearing in the tensioner.

I've been told the squeaky serpentine belt is a typical 300TDi problem, which also manifests itself in Defenders and Range Rovers. When I bought my Disco 1, it had about 20 K miles and already a nasty whine. The ANWB (Dutch RAC) tech guy told me it was the tensioner - it was not. Land Rover told me it was rust - it was not. Someone on some forum said the Gates belts squeaked a lot less - and he was right. I replaced my old OEM belt with the Gates 78411 "special service" (or
78413, don't peg me down on that one) and the squeaking stopped. For a while at least. It still squeaked, but it squeaked a lot, lot less.Moreover, I've found the occasional squirt of silicone oil to be quite effective. The Gates belt, silicone oil and all, kept on going strong for about 50 k miles. When I got the Disco MOT'd - and the alternator checked (this forum:

The PQS numbered belts according to Marc are made by Gates and AFAICR the earlier OE numbered belts were made by Uniroyal BICBW. Perhaps they changed supplier, hence the superceded numbers because of a design fault with the belts? IME the noise is usually caused by worn or misaligned tensioner.
