Does anybody have the correct part number for the auxiliary coolant flow pump - the one that is part of the HVAC system and NOT the intercooler pump - and, for bonus points, an online listing where it is sold? I'll accept a cross-ref number for a compatible part (like for a Lincoln LS or whatever else it is used on).

#5 on the diagram:

V8 SC Cooling system


Thanks

Ken,

How the health are you? It’s been a while.

Can’t help with your part number, but what ever became of your parking brake trouble?

Still have the PB fault. I'm waiting on the weather to dry up here. I've come to the conclusion that it's linked to the wet. I found moisture in the trunk under the floor, but not where it's coming in. Either the lights or the trunk seal, I guess. Now I have a compound problem up front: knock sensor faults, plus cam and crank sensor faults. The common thread between them is a shared ground. And, what do you know? It only happens when it rains a lot, and I live in the Seattle area so half the year my car is a pain in the A$$. Since I'm quarantined, I figured I'd start knocking out the stuff I'd normally need to wait until the weekends or vacation to tackle.

 

Oh, and HVAC issues. Probably a fried computer. I bookmarked your massive thread on diagnosing that, so I'll dive into that here soon as well. First part of that trouble will be testing the DCCV (again - I replaced it a few years ago, but I guess they fail quick), and replacing the pump down there because it's leaking. I'll probably send my CCM off to be repaired, though.
