Title: electric water pump
Post by: irmsher elite on 11 November 2014, 20:30:08
help can anyone tell me when the electric water pump should kick in on the 3.0 v6 or if it has a relay and where it is in the fuse box  :-\ :-\ :-\ :-\

The one at the front by the rad kicks in when the engine is hot and you park up (along with engine fans) so that hot coolant is moved around the block to prevent localised overheating ...... no idea where it's fused from  :-\ :-\

There's one on the front? :o Heard only of the one under coolant tank making heating more efficient. If you mean that one then it should run always when power on/car running.

Yes  ;) at the side of the rad at the top ..... can't remember which side, but it's only one or the other  ;) runs as above.  :y

(It's exactly the same as the one you're talking about though)

Is that an FL or vauxie only feature since I've never seen one :(

My MFL V6 was fitted with one, as I'm sure all V6s are, not sure about the 4 pots  :-\ I can't see that it's Vx only as it's a simple means of preserving your car engine from cooking itself after a run when ambient temp is high

One pump is mounted vertically on the rear face of the radiator, next to the battery... possibly v6 only?

The other, identical, pump is part of the Winter pack, possibly facelift only, and always fitted if heated seats are present. It is mounted horizontally on the inner wing between the header tank and the chassis rail.

One under coolant bottle is part of winter pack, I believe from 1998 onwards (and I believe only on Climate equipped cars)

So factory fit on all facelifts except GLS WITHOUT front fogs and heated seats :y

Here in Finland we have had that "circulation pump" as we call it all models starting from first PFLs. But then again never seen or even heard the front one :o  Strange..

Perhpas Finland doesn't get warm enough for the engine to need additional circulation when it's stopped  ::) ::)

That might be ::)  really strange still, sounds like a really smart system :/ Wonder if one could retrofit that by jumping power from rad fans power suply ::) ::) ::)

It is possible mate absolutely, but if you did it with using two fuses you have no chance to loose two cooler elements in case of one faulty fuse.  :) Must admit I'm not sure of being two fuses in manufactured cars at all...  :-\

That sounds like an easy install so me, might jump the power before the fuse and place separate fuse to extra WP :) Possibly going to drive on a race circuit next summer so all the extra cooling is good. Still priority would be to install external oil cooler hence original one has been blocked&bypassed on my new motor :/

Sounds like a load of messing around when you could have just added an external one. IF it is necessary. I'd probably be fitting an oil temp gauge of some sort before adding stuff wily-nily.
