Leaking auxiliary water pump

[mr.ots 10]

I've noticed I have a slight leak from the auxiliary (also know as additional) water pump situated behind the rear righthand corner of the cylinder head on my VR6. I got a quote of £70 from the local stealers for the complete assembly (no individual parts were listed) but it appears the leak is only from the lower black plastic part where it has a joint and seal secured by three screws.

Has anyone had any experience of this problem and is there an easy way to rectify without buying a new assembly. Can these seals be obtained individually elsewhere?

 

Any help would be appreciated.

you can only replace the whole unit................but it could be worse.when mine went it was only £141+vat for the part :roll: .............lucky for me mine was under warranty :wink:

Apart from a possible botch job by yourself the unit is sealed so nothing can be replaced, unfortunately I had the same problem, not cheap but a damn sight easier to fit than the primary pump!!

My aux water pump has been weeping for the last 4 years. As its not a large leak (no water on the floor, coolant levels fine between top ups at service, just a tell-tale green corrosion streak on the unit) I just leave it. Each time it's serviced the dealers put it on the watch list and reccomend leaving it till next time.

 

Now I've said that next time I start it up I'll be pissing G12 through the front grille.

Mine's pretty much the same, just a very slight leak and water marks on the hoses. Doesn't seem to be any noticable drop in the header tank. Maybe I should leave it for now and just keep an eye on it.

 

Thanks for the advice guys

tbh if its only water marks on it i'd leave it as is..............i had mine replacced when there was a wee pool on top of the g/box

After driving the car I can see a few drips on top of the rubber grommit on top of the gearbox. If I start to notice a drop in the header tank level I will replace it but it seems fine for now.

I had mine replaced about 6 months ago. I'm impressed you could spot what sounds like a tiny leak - I couldn't see anything coming out of mine, and the header tank was losing half its volume every few days!

 

The o-ring between the impeller shroud and the pump housing had completely perished, so no wonder it was leaking. Cost about £130 including labour, but that was at a specialist.

 

Quite a good little pump. We did try and turn the old pump into part of our Le Mans constant flow water pistol, until I cracked the shroud completely!

:lol: I do find your signature very amusing, although I too suffer from those modifications!
