I've read a few posts on here asking what somethings are under the bonnet where the answer has been that they're some kind of extra coolant pumps,one being on the radiator and the other near the header tank.I couldn't recall seeing these on mine,so while changing the thermostat on Xmas day I thought I'd take a look.I think I've found the radiator one-a small cylindrical affair clipped/fastened to rad shroud near top hose with an electrical connector going in at the top yes?Of the other there is no sign.Were these a specified option not fitted to all cars?or is my 3.0 F/L Elite missing something that should in fact be there?Of the 3 hoses that attach to the header tank the small one runs forward to radiator(?)second slightly larger one to front of engine and the 3rd larger,lower one appears to go to a metal tube running alongside the engine.

.... Of the other there is no sign.Were these a specified option not fitted to all cars?or is my 3.0 F/L Elite missing something that should in fact be there? ....

my better looking MFL  wasn't fitted with one, but I thought all face lift cars were fitted with one .....

Only fitted as part of the Winter pack on FL aka an option on GLS and standard across the rest of the range

Are they only on the Auto's, for the extra Trans Oil cooler? 

[Sir Tigger KC]

Must have been an option as mine only has the one on the rad.

All three of my manual ex plods have had both pumps.

Will check when I get home, but defo part of the Winter pack, but might include headlight washers so could be Cdx and above

the one on the rad provides movement of coolant, when you stop the engine, around the block to prevent localised overheating in high ambient temps

Winter pack deffo standard on later CD and up

Extra pump might be for 3.0/2.6/3.2 only

none on my 1999 3.0 Elite  .... cruise lived on the inner wing where the pump would've been

I get a feeling the cruise equipped PFL (and possibly FL with superior 2.5/3.0 engines) didn't have the pump under coolant bottle)

Doesn't this pump let you run the heater with the engine stopped for a short while? My MFL didn't have this function

No, as Andy says that's where the cruise lives.  Maybe that second pump under the bottle was only on DBW models?

My MFL MV6 had one

Did it have cruise? If so how was there room for both pump & cruise gubbins?

They share a mounting point, but don't know if there are any clearance issues... the pump sits almost on top of the chassis rail iirc
