i know its advisable to change the waterpump on your car/v6 when you undertake a timing belt change, i just wondered if the interval was the same on the 3.2 as it is on the other v6's or whether there was a longer period between changes?

you advice gratefully appreciated

It's an identical setup as the other V6s, so the same advice applies.

Since the cam belt doesn't drive the pump, it's less critical than on a 4 pot, and more a case that, if you're paying someone labour to change the cam belt, it might make sense to do the water pump at the same time.

Personally, I don't change the pump with every cam belt change because, if I did have issues with it, it wouldn't be the end of the world, just an hour's job to change it.

If I had a "new to me" car with an unknown coolant history I might change it as a matter of course as it could be less reliable, and removing the pump allows a more thorough coolant flush to be carried out.

At the most I would say change it every other cam belt change (80K miles).

Thanks Kevin. I will do mine as part of the rebuild following hg failure but useful to know for future reference

On my third omega. 2.5 to 147k.

3.2 to 105k

This one, 3.2 with 67k on it. Just changed the cam belt kit, and bought a w pump as well. Didn't fit it as the original had zero play in the baring and spun nice and smooth. It will go on next time though.

I have so far never fitted a water pump on a v6 of mine, and never found any play or concern with them.

However I concider myself lucky in that regard on the 2.5 in my pre forum days.

I found this the hard way, and only about 3 months after I had the cam belt changed..... so new water pump and another cam belt, as failing pump damaged it......

I've maybe done 300,000 miles in Omega V6s and never changed one yet
