Re: Auxiliary water pump wire
Hi what do you mean by added bump please mate and I’ll let you know. Any info on where the brown and red wire might go to on your engine? Do you have any additional sensor that I don’t seem to have? Thanks in advance! Appreciate all the help I’ve had from the great forum members. Loving the T25 comm...

Maybe I just need to buy the metal manifold and...

The engine looks like an AAZ to me, but im not by an...

Re: Auxiliary water pump wire
Thanks again Aidan. How do I upload photos please? I’m working on the van tomorrow, so I’ll come back to you once I have a look. The only plug that looks free seems to be on the throttle body.

Auxiliary water pump wire
Hi fellow T25 owners. Please help. I bought a van with what I’m pretty sure is an AAZ engine conversion. The auxiliary water pump does not come on and I’ve found a wire that when I touch it to ground I hear the pump running. Brown/red. Where does this wire lead to, it’s snapped and I can’t find anyw...
