I rebuild pumps for a living, little ones to huge ones, the seal in the water pump is known as a mechanical seal, a spring pushes a white Teflon disk against a lipped rubber washer to make the seal, Fun Fact: If you touch the white Teflon disk or the rubber lipped washer barehanded, the oils from your fingers will cause the seal to leak, we always wash the Teflon and rubber in acetone, and wear silicone gloves when we assemble the mechanical seals.

The Mustang 3.7l is an external water pump as its rear wheel drive based same with the F-150. All the Ford vehicles that were front wheel drive based such as the explorer, the 3.7l had an internal water pump because Fords brilliant engineers thought it would never fail. You should have told them it's not an internal water pump in the Mustang, which most independent repair shops believe it is as the 3.7l has a bad reputation for internal water pump failures lol.

Ford just seem to love these sorts of design ideas. Like, let's design the body so that when the windshield gutter drain gets blocked with leaves or whatever, it will overflow straight onto the dipstick for the transmission, which really isn't waterproof, so the rainwater will mix with the ATF and un-glue all the clutch pack friction. I'm sure it saved like, 10c a vehicle to do it this way. BTW you're going to be in real trouble when Blue wises up, learns how to edit, and starts his own channel.

I imagine that Ford went with the internal water pump on the fwd because of packaging constraints, however that must've been a way to separate the bearings and drive sprocket in such a way as to make this failure a lot less likely - but there's also the factor of cost. In the end, as in most things the devil is in the details. A reliable otherwise good design brought to its knees with one seal and bearing.

Wife's 2018 3.5 explorer water pump went out. IF YOU HAVE COOLANT DRIPPING FROM THE A/C COMPRESSOR, TIME TO CHANGE THE WATER PUMP. Shops and the dealership quoted me $3-5k, it's a 13hr job. Did it myself, take your time, make sure hold the cams in place, change the oil 3 or 4 times after. The coolant dumps into the oil pan when you pull the pump.

I actually really like the 3.5/3.7l engine, with the exception of the internal water pumps. If you own one of these engines, I would suggest doing the water pump as a maintenance item at a certain interval. Like every 80k or 5 years. Use a high quality pump. You are going to spend a considerable amount of $ on the job, but cheaper than an engine. The Explorers and Tauruses, I can do them with the engine in the car in about 4.5 hours (flat rate is 10). The smaller chassis such as the Edge, I don't see enough room to get the cover off. So out the bottom it goes.

On the Edge, i remove the motor mount, raise the motor enough to remove the top 2 bolts of the motor mount bracket from the engine, then I remove the lower dog bone, loosen the trans mount through bolt, then loosen all the subframe bolts and remove them from the passenger side to lower the engine enough to remove the lower bolt of the motor mount bracket. While it’s lowered i can remove the p/s pump bolts, serp belt tensioner, balancer, and all but 2 of the cover bolts. Then raise it back up for the rest of the job. Sounds like a hassle just for the one motor mount bracket bolt, but it really doesn’t take that long, and it provides a lot of access to the rest of it and makes gasket surface sealer cleanup a bit easier, and sure beats pulling the entire engine. The stupid thing is, is that ford has placed a hole in the frame rail near the location of that lower bolt, but it’s only on the outer web of the frame so it doesn’t pass through to access the bolt. A properly placed 1” hole saw could save a lot of hassle, but I’ve never done it.

Just so you know, water is no different than oil when it comes to hydraulics. Water may have caused the damage to that oil pump, but it would have been due to it's lack of lubricating values rather than it causing some kind of hydro-lock.

I agree with the post-mortem comment on the oil pump. It's possible that the "oil" had basically emulsified into grease, and the outer ring, as you said, developed way too much resistance to rotation - and the inner ring fragmented at is weak points. It's also possible that the emulsion's viscosity was so high that the oil pressure relief valve could not bypass enough to keep the head pressure on the pump under control, resulting in a near flid lock that caused the ring to fail. If I had to choose one scenario, I'd favor the latter as the explanation.

Thanks Eric! you are always a part of my Saturday night routine!😊👍

As much as I hate to say I told you so, especially for the poor person who had to buy a new engine, I posted that EXACT failure mode on the last video you did of that engine. Because of the position of the water pump, it is subjected to the full force of the engine. The water pump is a pivot point on the timing system. This is in contrast to something like a Nissan VQ35 where the water pump is also driven by the timing chain, but is not a pivot point. It's just an accessory. For a little bonus content, take apart that water pump and you'll find the single bearing inside wholly inadequate to the task. And once the engine wears some slop into that bearing, the shaft seal is on borrowed time. The pump leaks right out the front and into the sump. Bye bye bearings. If you look at buying a FWD Ford with a 3.5 or 3.7 and it's got VVT solenoid codes, RUN AWAY! The pump failed, dumped coolant into the oil pan and the oil system pumped it up through the motor.

The coolant mixed with oil did the cleaning job. Unfortunatelly this mix doesn't make a good lubricant for the bearings and piston rings.

@@Tovvvija But it wasn't the owner's fault. Most of the blown engines we see here are because they didn't do the maintenance, but who could've prevented this disaster?

Used to own an 09 Flex with the front drive version of the 3.5. Noticed a few drops of coolant on the garage floor. Called a Ford dealer to inquire about a water pump replacement, found out that Ford considered it part of the powertrain for warranty purposes. Dealer saved my butt AND my engine.

Loved that ending. Also caught that thanksgiving reference at the beginning. Good video.

Water pump behind the timing cover? That's the main reason I got rid of my '17 Nissan Frontier 4x4 pickup. Well, that and the fact that, when I moved to Indiana, it barely fit in my built-in-1931 house's driveway - never mind trying to put it in the garage. Putting a water pump inside the engine, has got to be one of the stupidest things a car company could do... until you realize that they can charge you a small fortune to replace it. Assuming that the engine hasn't self destructed when the damn thing fails... Gawd, I wish I had my '63 VW Beetle back...

Wife's Ford just cost us $14K at the dealership for engine replacement for this, 5 yr. old. 50k mi, 8 mo.s left on payments. Not an easy choice to make, 3 yr. unlimited warranty. Changed oil, monitored fluids religiously, I am old and retired. But w/ wife driving she does not understand the vigilance required when coolant temps start to increase barely, has been 100+ deg. outside. On the other hand I just replaced the water pump on my '95 F150 for < $100 because I noticed the rust on the weep hole, like you're supposed to be able to do - FORD!!!

The rwd engines don't suffer from the water pump failure, but the channel plate that's inside, with the idler gear on it, leak coolant into the crankcase. The leakage is much slower, so the engines end up with heavy black sludge everywhere, as the coolant Ford has used in their products is similar to dexcool. That Mazda version, uses Asian dark green which doesn't do the black sludge, just the milk shake.

I’ve had a ford Explorer PIU with the 3.7l and have our well over 100k on it and it’s been so reliable. Love it, had the waterpump replaced before hand and it’s been an amazing vehicle! 300 plus thousand kilometres and rising! Love it

Congrats, you DID make the good video you mentioned. I learned about a neat front cover removal method. Thanks to the professional mechanics who keep Eric updated! Also, I'll never buy a vehicle with an internal water pump.

37:13 My line is....well, one of them...internal water pumps driven off timing equipment. Or, to be a bit more general, water pumps driving off the cam timing system in general, 'cause a lot of belted engines will drive their water pumps off the timing belt and it's not unheard of for a water pump to get bad bearings like this one did, strip the teeth off the belt, and snap it. On an interference engine that's game over just as it was for this ecoboost. So yeah, for me, if the water pump is driven off the cam timing system, the engine's worthless.

The best practice for these seems to just plan to do the water pump every 100K-miles. That's my plan for hte 3.5L NA FWD in my 2013 Flex. This is one of the later model revisions as the water pump has a double chain. The earlier ones had a single chain sprocket and were very notorious for failed water pumps.

I have a 2013 Flex, with the NA 3.5 FWD. So far the entire car has been great. Is there any data that suggests this modification you mentioned results in fewer water pump failures? I hope so. Thanks for the info. about the modification, I had heard that there was a modification at one point but no one could tell me the year or what the mod was. Good luck with your Flex. I think they are really good cars overall.

A bad block is only good for one thing - A novelty coffee table ! :-)

Your disassembly and explanation is excellent. When I was deciding to buy a van which I needed for work, all videos of Ford transit 3.5 engines complained about the water pump being located internally. So I decided to buy a Chevy express instead. Since I could not find any Chevy vans in my area I was forced to take a chance and bought a Transit 150. To my surprise one day when I was checking the van all over and under as well, i noticed the external water. I was totally happy. No video had ever stated that the internal water pump ONLY applied to transverse mounted engines. You are the only mechanic of the many videos I watched that explained this. Keep up the great work.!

You often can tell in a few different ways. It'll start to lose coolant from the drain they designed at a certain spot and eventually run hotter and hotter. Then if it fails here where the water pump bearing goes you start to get critical really quick. Not only mixing oil and coolant, oil dilution etc.. Also since it's driven off the same chain as timing it can throw time off. From what i found when one at work had the worst case scenario happen, needing to add coolant is usually the tipoff. If you start to feel any sort of rough idle or not running right shut that thing off right away. It was topped up with coolant and ran for a good amount of time before the engine basically had a death rattle and that was that.

@jamesengland7461

Nope. Checked both regularly, no loss of coolant, not low on oil, nothing from weep hole; water pump just dumped all the coolant in the oil pan on my wife's commute to and from workin one day. No warning. Had it fixed. 2 weeks later we discovered a bearing had been ruined, and now the engine is toast.

The Gallagher reference at the end got a hearty laugh from me, and some rather bemused memories of my youth from watching the guy on SHO. It was thanks to him I learned about Wall Street Week, ironically. Thanks Eric.

I picked up a certified pre owned 2018 explorer with one of these engines in it, unaware of the water pump in the timing cover issue. Thankfully I learned about it in time to purchase the ford extended warranty, so I've got coverage over this type of failure for a couple of years. Will definitely part with the truck once the warranty is gone.

I highly recommend changing the sparkplugs before the gap gets that big. These engines tend to melt coils and take out the coil drivers in the ecm if you neglect the spark plugs for too long.

Knowing these engines are reliable, especially the RWD applications with the external water pump, is very nice to know and reassuring.

Use full synthetic and change the coolant often in these engines and they will last a long time.

nothing you said would have changed the outcome in this case...

Worth noting that the water pump weep hole also comes out behind the alternator, which in turn is above the ac compressor. Assuming the water pump weep hole never becomes packed with dirt, any trail of coolant could very easily go unnoticed. I don’t see any reason why coolant in the oil would cause the oil pump gears to fail, as oil is a liquid just like water. I suspect they are simply just weak, as billet oil pump gears seem to be a common upgrade any time someone builds a late model Ford engine for performance use. I think that most of the bearing damage in this engine was from the oil pump failing, rather than the oil being ruined. Also noteworthy that there was no milkshake oozing out of the block where the oil filter housing bolts up. I suspect the oil pump failure and the subsequent racket just added to the noise this engine was already making do to the failing water pump. I think this engine died of a sudden oil pump failure, while in the process of dying of an unrelated water pump failure.

Informative and amusement in the same video, Got to love it.

My sons 3.7 mks milkshaked on expressway no warning, put a 70k motor back in, changed timing set and replaced water pump w/new OE ford one, ford recommends pump changed every 100k, old motor had 171k on it and I wasn’t aware pump was in crankcase, another ford oops!

Those threaded screw holes are called push off screws, they have been around in the aviation/aerospace industry for a long time. It's too bad a reliable engine like this has such a simple weak spot. SMH. I really like that no mater how bad the engine you still remove bolts in the correct pattern. Kudos to you for this.

I literally just commented asking for this engine yesterday on your last video awesome!

Wow good tip with the timing covers on these. It's nice of Ford to actually put the threaded holes in that cover so you can use the bolts as pullers. I've used the same technique to pull stuck brake drums off, however you can damage parking brake components/hardware if you overdo it. I learned that the hard way.
