Leaking auxiliary water pump

Recommended Posts

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.

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

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!
