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.
The 3.5 engine is garage with this design. Had an Edge from new and out 150,000 miles on it in 13 years. I was always dreading this failure and luckily dodged it before selling it.
Awful design by Ford to put the water pump inside the engine. I almost bought one of these used a few years ago, but backed out after reading about 3-4k jobs to replace a water pump at 180-100k miles.
Pretty sure this is the motor that needs the engine dropped to do waterpump and timing components. Bad bad design
The 3.5 5th generation Explorer has an internal water pump driven by the timing chain. It’s an enormous pain to change requiring significant disassembly (nearly 12 hours of labor) and generally includes replacing the timing chain in the process since you’re already in there, plus when it fails it can easily mix the coolant with the oil and destroy the engine, all that’s keeping them apart is a little seal.
I have a 2021 BS BB and I’m on my 3rd water pump replacement. 1st one around 20k miles, 2nd at 40k, now at the dealer with 51k miles and replacing it yet again.
I just had the alternator (bearing went bad) and water pump changed (coolant leaking through the weep hole). Still the original block.
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.
I got a water pump there for 80 dollars ford wanted to sell me for $560, I've spread the good word ever since
from 88k to 150k miles, I put in a new water pump ($27). otherwise very reliable and easy to find parts as there are tons of them in the junkyards.
