This could be a challenge.
« on: 08 July 2017, 07:30:15 »
I've finally bitten the bullet and decided to change the 3.2l cambelt etc. myself, in spite of old age, associated aches and pains, and not having done it before. I bought the excellent CD years ago.
Just ordered a Contitech kit and trying to find a suitable water pump as an alternative to the main dealer quoted price of C.£180.
There are quite a number of low priced alternatives on-line; (£25/£35) and a Bosch version at around £95. Anybody got experience of the quality of these, or a suggestion as to one which would do the job satisfactorily.

I believe that some pumps have plastic blades and that these are the ones to avoid.

They say that old men need a hobby that makes them think and use their hands, otherwise they fade away and die. Congratulations in taking on the cam belt change job.

 Forum opinion on changing the water pump on V6 engines is changing, 'cos it is not driven by the cam belt, unlike the 4 cylinder engine. If it fails, it will not wreck the engine, just need changing, which will admittedly involves much of the same dismantling.

Thanks for your replies, and the encouragement Terry P.
I don't think the pump is problematic but thought it might be prudent to change it when doing the cambelt, if the cost is sensible, in view of the dismantling necessary if it should fail. As it isn't cambelt driven, failure obviously wouldn't be an out and out catastrophe so I'll probably not bother if it looks in good condition when I examine things more closely.
Robson. I can't find your Whaler pump. Did you mean Whale? and do they do automobile pumps?
Thanks again.

Thanks Robson. Their US site doesn't list Opel, Vauxhall or Opel believe it or not. Can you remember how you found your pump?

I think you will find that the CD shows twin adjustable tensioners, whereas the later kits only have the one. Still a very useful guide though. :y

James did my 2.6 cambelt for me whilst I watched, and he said that if the pump is original (it was) and feels ok, thenleave it, as pattern and even genuine Vx are not as good nowadays.
He lubricated the bearings, span the pump and it sounded great.
I hope the Fates aren't listening when I say that it is still fine!
Go thou and do likewise.....

10 years ago when VX charged £20 odd quid for a V6 water pump it was thought sensible to bung a new one in while the front of the engine was dismantled.
Now they are silyl money, and possibly not as good quality, the accepted wisdom is "if it isn't broke, don't fix it".  :y
