300tdi water pump

Does anyone know of a good make of water pump?
They all seem to have the same problem, namely the shaft bearing/bush.
Over the years I've fitted all sorts of different makes and grades both OE and aftermarket, but they all seem to have a fairly short lifespan, couple of years, then they start to squeak, or even just straight forward fail.
Am I doomed to being raped by the main dealer to obtain a genuine part.

Quinton Hazell used to be OK, they may not be now.

Out of interest, do you tighten the fanbelt using a six foot scaffold tube?

No need for the scaff bar, they have auto tensioners. All posh stuff on these modern motors

Serpentine belt on those? My V8 D2 had that, and it worked quite well.

The reason I asked is that I have seen some stupid tight fanbelts over the years, which has a detrimental effect on water pump and alternator bearings.

No scaffolding was harmed.
Tensioner is new(ish)
Belt is correct one - there are 2 lengths, for no apparent reason than ****s and giggles
Just seems that the quality of parts in general is going downhill.

I thought I had read somewhere that the difference was due to different size alternator pulleys. I thought the later alternator had a smaller pulley so spins faster and more energy output - but this is based on me trying to remember what I read when I ordered mine about three years ago!
