Replacement of Aux. Coolant Pump?
Has anyone had to replace the Aux. coolant pump? It is a small pump on the drivers side underneath the front end just behind the radiator, and mine is whineing something fierce... just wondered if anyone else has tackled this job.
I think I may do that, the MECS Pump, and flush both coolant systems and refill, since I have 51K on the vehicle and both pumps require losing fluid and replacing...
Whatcha think? What's the process for the flush and should I buy a flush fluid and follow some process to properly clean it all out? Can you get everything out afterward?

does anyone have a part number for the other auxiliary pump i cant find it anywhere and my 06 MMH has been giving me some SSN problems. i have changed the mecs pump believing it was that, completely unrelated. ended up being the temperature gauge. in the process i changed out the water pump and thermostat. the only thing i can find that isnt working is that small auxiliary pump on the drivers side but cant find any info on it.

I know I'm late to this discussion, but I'm pretty sure Ford has issued a recall for these failing MECS pumps.

I had the SSN problem a few years back. I replaced the MECS pump myself. After the recall was issued, I was able to get a refund from the dealer for my costs to buy the replacement pump. Hope this helps.

Re: Replacement of Aux. Coolant Pump?
I replaced my OEM MECS pump at about 51,000 miles on spec since I was seeing entries in here about it failing. Ford has a new design pump. If you order one (~$180 several years ago) you should get the new design one. Ford just sent out another recall to replace the original OEM pump. So you may be able to get a Ford Dealer to replace yours as part of the recall.
