Water pump OEM FORD or Pierburg

I just had the alternator (bearing went bad) and water pump changed (coolant leaking through the weep hole). Still the original block.

I got a water pump there for 80 dollars ford wanted to sell me for $560, I've spread the good word ever since

I went from that just up to the Pierburg ones and it was a night and day difference.

have a pierburg water pump, it’s holding up pretty well.

Trying to replace my water pump on my 2000 Ford Ranger 3.0L (flex fuel). I can’t find a video that performs this repair on my model; 4cylinders and v6 4.0 yes, but not the 3.0. There’s 12 bolts on the WPump, 11 are EZPZ, one is behind something else. I’ve got everything off except for one bolt that is stuck behind the “mount” for the pulley tensioner/AC compressor. It’s not the power steering pump, it’s not the AC compressor, and it’s not the pulley tensioner - *it’s what all 3 of these things are mounted too.* I’ve loosened 3 bolts that seem to mount this “mount” to the engine block, but I must be missing 1+, as it won’t budge.

New parts should be in tomorrow (Pierburg pump). I'll update again after everything is back in! As a small detail, I noticed a brown seal-looking thing stuck in the impeller of the water pump (Continental, BMW logo. Probably factory) I am thinking the pump internally failed while spinning, and the internals took the hit and self-destructed. Hence the total BSD failure code. Just a guess though.

This is why I’ve avoided the 3.5/3.7 Duratec engines in transverse (front wheel drive) platforms. It’s just fine in rear wheel drive applications as those use an external pump driven by the serpentine belt.

Yup, that's happens when they decided to put water pump INSIDE the engine. Ask me why i would never own a newer Ford. Oh, and a timing belt cooled by engine oil, what could possibly ever go wrong? Last 10 years Ford has managed to come up dumbest engine designs.

I had the same issue with the same Ford motor 3.7 in my Mazda Cx9, it is internal water pump

I had one go bad on my Ford flex... The pump is inside the timing chain cover. Most places have to drop the engine, I got lucky and the place I went the guy was able to do it without removing the engine.
