3.5L Duratec/3.7L EcoBoost Timing Chain and Water Pump Replacement

New, updated video coming soon! Link will be below when it's finished!
In this video I show, in detail, how to replace the water pump and timing chains on a 3.5L Ford Duratec engine. The 3.7L EcoBoost is similar, with some differences that should be easy to figure out. The 2 engines shown in this video are out of a 2010 Ford Edge and a 2014 Ford Taurus.

[@marksd5650]

I’m a new subscriber. That you for this video. I wish I’d found you three weeks ago. My coolant dumped out of my 2013 Ford Flex three weeks ago. I pulled over immediately and called my mechanic, who said he couldn’t do the water pump because he didn’t have the “tool” to hold the cams. Hmmm, well I called a few Ford dealerships and they both said that a job like that: they were booking a month and a half out. Huh? What the hell? Well I found a shop that would do the job and it was $1600 all in. Fine. I want to thank you for this step by step video, which I watched beginning to end, and I’m so pissed off that my mechanic said he didn’t have the cam holders that I bought a set from Amazon a few minutes ago just because. I don’t work on my cars anymore but I collect tools because I like tools and now I have a set. No one said anything about cam phasers. Thank you for showing me which tool to buy for the cams. Best Regards

[@darkhorseautoanddiesel]

You're welcome. Like I showed in the video, technically you don't even need the tools, it just makes it way easier. Sounds like that mechanic doesn't know how to do the job, or doesn't want to. Even if he didn't have the tool, as you proved, Amazon can help that quickly. Now that you have the tool, if you ever need them, you have them. Maybe it's time to start working on car again.

Thanks for the compliments! Helping people is why I started making these videos. Tiny little scratches will be visible. As long as its just cosmetic you've got nothing to worry about. The silicone will fill those in. I always recommend making the final pass perpendicular to the way fluid would leak out as well, just to be sure.

[@BlueSkies-pd9og]

Just a heads-up, as it relates to a recent query @rockwitdom9765. Early models from 2011, particularly the MKS, were equipped with the older 2010 engines. Mid-year, Ford shifted to next-generation engines. The timing components of the later 2011 builds underwent significant changes, including a wider chain, broader guides, a redesigned upper tensioner, a two-sprocket water pump, and extra phasers. You can identify the engine variant by counting the VVT solenoids on the valve cover (you might need to remove the cover for certainty). My car, a 2011 MKS 3.7 Base, manufactured in May 2010, has two VVT solenoids, one visible on each valve cover. When sourcing my engine parts, I've learned that referencing the 2010 MKS is more reliable. The dealership, using VIN, doesn't take into account the vehicle build date, often resulting in wrong parts. Anyway, I'm planning to undertake this job later in the month, including the oil pump. The video was excellent, especially the part about identifying the new, longer guide bolt, which I couldn't find elsewhere. I'm considering a one-month subscription to ALLDATA DIY for the torque specs (for the 2010 MKS) and to verify the procedures. Thanks again for the effort put into making this video!

My 2014 Ford Explorer Sport (turbo/Ecoboost) just had this timing job done. Ford did it (no one else would). 17 hrs labor. The tech did it with the engine in the car (thats the way he does it, apparently). Did a good job; runs really smooth now. Chain had jumped some teeth and I had 5 codes thrown. Expensive! I also had spark plugs and water pump done. I had a 2013 Explorer that needed a water pump, and for that they dropped the engine out and did it on the floor in less than a day. Timing chain and a few other parts as well. Stupid design.

[@tomyutz1950]

Thanks for a great video. Risky to pry the timing cover off. You may crack the timing cover. Use the threaded holes located 2 at the top and 2 near the bottom. Use the timing cover bolts in these holes to back the cover off of the engine evenly. Also, it's not a good idea to whack the harmonic balancer back on. There is a harmonic balancer install tool designed to pull the balancer onto the crankshaft.

That's what my MKT needs. Since it's only gonna take about an hour and a 1/2 I think I'll do it.

[@BlueSkies-pd9og]

For a single phaser 3.7 (2010 Mks), here is the secondary sprocket torque sequence from ALLDATA: 30 ft lbs > Loosen one full turn> 89 in lbs > 90 degrees. As this information conflicts with the video, I'm confused if ALLDATA is correct

[@darkhorseautoanddiesel]

I believe alldata is correct. At the time I made this video I was unaware that the 3.7 used a different torque spec. Unfortunately, that I'm aware of, there's no way to edit a video to add info once it's published. The problem is, if I edit the video on my computer and repost it, it acts as a totally new video so it goes back to the bottom of the search pile. I do have a new, updated video on this job recorded, I just haven't had the time to edit and post it yet. I recorded it just this last week 😆

[@BlueSkies-pd9og]

Yes, if I went to 180 something might have broke...90 is super tight. The single phaser motor has short bolts. Dual phasers are at least twice as long...infering more torque.

[@darkhorseautoanddiesel]

@@BlueSkies-pd9og Well the 3.5 in the video, the main one, was a single phaser, and it called for 180. What are the part numbers for the bolts on the motor you worked on? That may shed some light on this. If they're the same part number, maybe it doesn't actually matter?

[@kevinsteinmetz8127]

2010 Ford official manual agrees with alldata procedure for the 3.5 non ecoboost

[@chrismusic69]

While this is a great video with very good information, I would like to point out a one big concern. I highly recommend NOT using the cam position tool as a holder while torqueing the cam bolts. These tools are not designed to withstand that much pressure, they are solely to make sure the cams are in correct position for timing. Instead use a proper size wrench on the cams while torqueing to spec. Also DO NOT use the chain to hold the crank while torqueing the crank bolt. This can cause premature chain stretch. Instead use a prybar inside the slots of balancer to hold the balancer in place during torqueing. Other than these concerns you did very well.

[@talaatkanafani3383]

Hi can i move the crankshaft alone against clockwise while the chain off to put it on the 4 o’clock position for ford explorer 2019 ? Actually need about 180° turn against clockwise to reach to its point Can I Thank you so much

[@zzoinks]

I'm not an expert but i would think that both the cam shaft and crank shaft should be moved together attached with chain, or by same angle(?) else you risk causing the pistons to hit the valves (since this is an interference engine).

[@andrewvirtue5048]

I've only ever done inline-4 engines. Mostly 2.2 ecotec. I think it would be wise now, to go ahead and replace the headgaskets. On a V6 can I come back later and leave the timing alone to do the gaskets or would I have to disassemble the timing again?

[@darkhorseautoanddiesel]

If the head gaskets are fine there is no reason to replace them. That is just asking for more problems. If you mess up, now you've got a head gasket leak that you didn't have before. Head gaskets can last decades and hundreds of thousands of miles. As long as the engine never gets over heated and the cooling system is maintained fairly well (to prevent corrosion), there really isn't any reason for failure on a well designed engine. They aren't considered a wear item. On an overhead cam engine, the timing components have to be removed to replace the head gasket since the cams are on top. So no, you can't replace the head gasket and leave the timing alone on this engine. On an over head valve (cam in block) engine you can, but those are rare these days in automotive applications.

[@Marek-pm8cz]

@darkhorseautoanddiesel I want to thank you for this video as it helps me understand this engine. I've noticed, that timing cover seems to be covered in engine oil mixed with dust - do you know what was the reason? I have oil leaks close to the both cylinder heads junction with timing cover ('V' shaped place on top of the cover) as well as close to the belt tensioner and I wonder if this might be timing cover sealant issue...

[@edgeofvamp]

The timing cover is hard to remove, but there are 4 threaded pass through holes near the dowels down low and 2 near the top that are there to drive yhe cover off without cracking. The holes just use the timing bolts, so save your self replacing the timing cover and use those go around and work them all little by little till it pops clear.

[@darkhorseautoanddiesel]

I have another one of these coming in the shop in a week or so, I'll look for those.

[@edgeofvamp]

​@@darkhorseautoanddiesellook at 15:50 timestamp. There is 2 bosses sticking out with threaded holes at the bottom of timing cover between the inner and outer 2 bolt holes both sides. Those are 2. Then look either side above the 3 bolt hole up from the bottom. There is another set of bosses sticking out with threaded holes. Those are you're self pry holes. They take the same cover bolts you just took out, thread in and just apply even pressure and walk them all in until the cover pops.

[@edgeofvamp]

​@@darkhorseautoanddieselAlso, I don't recommend it but there is a crank lock tool that goes in the crank sensor hole. It's not worth the extra work to do vs just keeping the cams locked.

[@darkhorseautoanddiesel]

I have no idea. Cloyes does make factory parts for some vehicles I believe, so it could be possible that the Motorcraft parts and Cloyes are literally the same. That would require some research to confirm or deny though. The engine that I showed that was done in the car, the customer didn't want to replace the phasers due to the cost, so those are likely factory originals (with over 200k on them now).

[@maolo76]

i got a 3.7. how long did it take to do the job with engine removed.?

[@darkhorseautoanddiesel]

That's hard to answer because I really don't keep track of the actual time I spend working on things. However if I were to take a guess, that guess assuming consistently working on it (which I typically don't, I work at a leisurely pace and triple check about every step) I'd say even never having done it before but following along with my video you could probably get it done in 8 hours or less pretty easily.

[@maolo76]

@@darkhorseautoanddiesel thanks it looks pretty easy with the engine out. I might take it to the shop to do it so i kinda want to know the time it takes to do all this work with engine out. Also, my coolant leak into the engine. I discovered it when a P0016 code . I check the coolant resevoir..it was empty. The engine never overheated or seized up. I only cranked the engine up to back out the parking space for tow truck. Do you think it can be save the engine with new waterpump? The dealer told me I have to get a new engine. But I think they didn't even do a proper diagnostic. They said I got sludge in the engine because I didnt do oil changes. I told them bs..they didnt want to admit the water pump leak.

[@darkhorseautoanddiesel]

The P0016 is a timing issue, specifically Bank 1 camshaft is out of time. That can get catastrophic VERY quickly. Stretched chain, broken guide, bad tensioner, or a bad phaser or soleniod can all cause that. Could also be a bad sensor. Your best bet is to replace all of it. The empty coolant reservoir, where did the coolant go? Did it leak out of the weep hole in the block (located on the left side, front on front wheel drive vehicles, of the engine near the front) or did it end up in the crank case? If it went out of the weep hole, there won't be any internal damage from coolant contamination. If it went into the engine, depending on how long you ran it that way, it might be salvageable. The apparent sludge in the engine might be from coolant contamination. If that is the case, it's a gamble. They are well built engines, but everything has its limits. You can take your chances and try installing a new water pump, chains, phasers, solenoids, guides, and tensioners (everything really) and hope for the best, or play it safe(ish) and get another engine, and while it's out, replace all of that stuff on that engine before installing it. TL;DR: If you have coolant contamination in the oil, as long as you didn't run it very long, then it's probably ok. By not long, I mean a few minutes. The longer it ran that way, the more potential damage is done.

[@maolo76]

@@darkhorseautoanddiesel most definitely the coolant spill into the crankcase. I got milkshake oil. I probably drove 30 miles to my destination. No CHeck engine light came on or my temperature went up. I turn off car for 5 minutes then turn back on.. The P0016 code appear. My obd2 said camshaft sensor. I drove down the block 3 min to shopping center. Got out and noticed puddle under car. Checked the coolant reservoir. It was empty.. There was coolant on outside of engine block on the oil pan. I guess it came out the weep hole. I towed it to dealer to check. Thry just told me i got sludge in engine and need new engine. They didn't really tell me what's wrong. But I know it was the waterpump fail. So basically my engine never overheated cause i monitor engine temperature with my obd2. It was around 190 to 200 degrees at the time. I got a P0016 code and milkshake oil. There's 197,000 miles on engine. It's a 2014 Cx-9 3.7L. I read it's a ford engine. Is camshaft sensor easy to change.?

[@darkhorseautoanddiesel]

@@maolo76 Ooooh... You can take your chances putting new parts on that engine, but that's a lot of time spent driving with a milkshake in the crank case. I really can't give you much of an opinion on what to do. On one hand, it might be fine for a long time after replacing those parts, but on the other hand, that's a lot of money in parts just to throw at an engine that might throw a rod within days of doing all that work. It's definitely a gamble. The code may have showed up because the milkshake oil might have ruined the phaser on that side, just a guess. Just because the reservoir is empty doesn't mean that there still isn't plenty of coolant left in the system to keep the engine at the proper temperature. You can actually be pretty low on coolant before the engine will overheat when driving normally. Unfortunately I don't know everything about cars and trucks, but based on my knowledge and the research I've done, yes, it is a Ford engine. That means you can get a 3.7 out of a salvage yard from a ford likely cheaper than one that came out of a Mazda. The cam sensors aren't terribly difficult to replace if I remember correctly, but unfortunately I think you probably have bigger problems than just a sensor.

There is nothing wrong with doing the oil pump while you're in there, I've just never felt it to be necessary. If the engine looks reasonably maintained, i.e. no sludge buildup, and has good oil pressure, the pump shouldn't have anything wrong with it.

You are not wrong. On front drive applications this engine uses the internal pump, likely due to packaging restraints, whereas rear drive applications use an external pump.

Quick question if you went ahead and took the heads all apart but now are going to reassemble it do you put the DOHC's in the natural position meaning the barcode on each cam has to be facing up? Then install the phasers back in the 11 clock ,1 clock, and 4 clock?

[@darkhorseautoanddiesel]

I don't recall any barcodes on the cams so I'm not sure what you mean with that. However, as far as orienting the cams, if the tools fit they are either correct or 180 degrees off. If they are off, you'll know as soon as you try to put the sprockets on them because the sprockets only go on the correct way. If the timing marks aren't in the right position once the sprockets are on, then you'll know the cams are off by half a turn.

[@mrboots066]

How come you don't line up the orange links and the white link with the timing marks on the timing gears, When you're setting TDC? Does it matter??

[@darkhorseautoanddiesel]

I'm a little lost on what you're saying. I lined up all the colored links to the appropriate marks on the gears. Maybe I'm misunderstanding what you're asking?

[@mrboots066]

​@darkhorseautoanddiesel. When you set TDC at first. I see you set the timing marks, but the old chain , those orange links don't line up? Also, the updated part, does the new bolt tighten down on the steel sleeve or does it touch the outer plastic guide because when I tighten it down, I can move the updated part in and out?

[@darkhorseautoanddiesel]

​@@mrboots066oh you're talking the initial TDC setting. Makes sense now. The marks on the chains only matter during the installation of the chain when new. Technically you don't even have to use them then, but they serve as a great indicator that everything is actually timed properly. Once the engine has been turned after timing has been set, it could potentially take hundreds of turns before the marks on the chain line back up with the marks on the sprockets. So as far as setting TDC for disassembly, the marks on the chain mean nothing, the only marks that matter are the cams and crank.

[@darkhorseautoanddiesel]

​@@mrboots066the updated part, you are referring to the right hand upper guide I assume? Did you get the new bolt that you have to use with it? It should tighten down just like shown I'm the video as long as everything is in the correct locations and using the correct parts. The bolt should tighten down the sleeve insert in the guide.

[@darkhorseautoanddiesel]

​@@mrboots066I believe it only tightens down on the sleeve, but I've never looked close enough to notice if the head overlaps any of the plastic. Either way though, once the 2 bolts for that guide are tightened, that guide should not move. If yours does, that tells me that the sleeve is loose in the guide. What brand of parts are you using?

[@sonsautomotive]

how long did your cloyes kit last?? most last about 8000 miles...

[@darkhorseautoanddiesel]

Both engines shown in the video are still running perfectly fine and they've been on the road for over a year now, with over 15k miles each. I put a cloyes kit on a 4.0L SOHC Explorer (notorious for timing chain failures) over 4 years ago and it's still going fine with over 30k miles. Maybe I'm lucky, but the rest of my life says otherwise 🤣

[@patriotprepper9175]

On the engine you have out of the vehicle with one cam phaser on each side did you only put one new bolt on each side of the motor? With The new bolt going into the phaser on each side of the motor?

[@darkhorseautoanddiesel]

No, it got new bolts on the exhaust cams as well. Even though it's not holding a phaser on, it is still a torque to yield bolt, so it should be replaced.

[@patriotprepper9175]

@darkhorseautoanddiesel thank you for replying!! When you was going over the part numbers the ones on the sheet of paper said there were only 2 bolts. Are the part numbers the same for all 4 bolts? 2 intake and 2 exhaust bolts?

[@patriotprepper9175]

@darkhorseautoanddiesel I'm working on my 2010 ford edge limited awd 3.5l v6

[@patriotprepper9175]

@darkhorseautoanddiesel getting the correct part numbers is what's throwing me off. 10/10 video though, very informative.

[@darkhorseautoanddiesel]

I had to watch that part of the video again 🤣 I realize now that I never gave the part number for the intake cam for the single phaser engines since it came with the kit. Your Ford dealer can get it for you easily though when they order the part. I'll have to include that number in the new improved video I'm working on for this job. The part number I gave for the single phaser engine is the exhaust cam bolt. With that AWD system, check out my video on changing the oil in the PTU. You want to change that oil, trust me.

[@lumberjackgarage193]

Identifix says on the 3.5 non ecoboost final stage to stretch only 90 degrees. On the 3.7 it says 180 degrees. What instructions are you using? It looks like your bolt didn’t break on the 3.5 so that’s good..

[@darkhorseautoanddiesel]

I was using a Chilton's manual as well as several online sources (whatever Google search led me to). Both engines in the video are still running perfectly fine so if they are wrong it must not be too detrimental haha.

[@lumberjackgarage193]

@@darkhorseautoanddiesel please don’t think I was correcting you. I was noticing the same things online everyone says 180 final torque. I did mine at 90 but wonder if it actually is correct.. 🤷

[@lumberjackgarage193]

I decided to call Ford directly with the VIN of my vehicle.. it’s a 2010 Lincoln MKX with the non ecoboost 3.5. They looked up the manual from Ford and it says final stretch 90 degrees.. so there must be some variances in those years.. I believe the 3.7 is 180 so just a little more information on these engines.. thanks

[@darkhorseautoanddiesel]

@@lumberjackgarage193 no offense taken. I have no problem being corrected when needed. I actually appreciate it. I'd rather not be one of those people out there spreading false information. I will do some research on that and make a video update and link to it in the original. I'd add it to the original but as far as I know KZbin isn't set up to allow adding to an already published video, and they way their algorithm works, I don't want to remove this one. Thank you! Honestly I don't know why they even put TTY bolts on those parts, they lock in place. TTY makes sense on something like the notorious 4.0L SOHC V6 that has nothing but friction to hold the sprockets in place, which was a stupid idea on its own.

[@lumberjackgarage193]

@@darkhorseautoanddiesel I agree, I was originally thinking my instructions were incorrect but since Ford confirmed them it made me feel better.. I watched so many other videos and forums. They all said 180 degrees.. it seems like the 3.5 ecoboost does call for 180 degrees to make it more confusing.. good luck though and thanks for the videos.. 👍

[@tman3944]

at 15:24, the duratech designers put holes on the timing cover so you can pry the timing cover with the bolts and not the pry bar. cool huh?

[@darkhorseautoanddiesel]

On certain ones. I didn't realize that when I made this video, and the main engine in it had them. However several engines I've done since, newer ones, don't have the holes. Definitely cool, as long as they exist.

[@tedpesyna8347]

They did that because you need to pull it so many times to replace the pump every 80000 miles, or leak and die.

[@christianmarche993]

Same engineers put the waterpump inside of the engine.

[@ZackRevenge]

What was the "delicate green wire"?

[@darkhorseautoanddiesel]

Apparently it is for the pressure switch on the power steering pump. I'm not actually sure, that's just what I've heard. I suppose I could look in the service manual wiring schematics and see what I come up with, but even that might not give me a solid answer. By the way, if you have electric power steering, you won't have that wire.

[@millerrussell7431]

Do you have a part number or web address for the kit you used?

[@darkhorseautoanddiesel]

The part number will vary based on the year and model, so giving you that might be pointless. I can tell you though, that I got all the stuff from rockauto.com. Select your year, make, and model, then read through the selections and find what you wanna buy. If you've never heard of them, I can tell you that they're legit. I've done tens of thousands of dollars of business with them. So much that my shop fridge is half covered in magnets from them since they send you a magnet with most orders haha.

[@Bear1097]

What kind of miles can you expect before having to do this??

[@darkhorseautoanddiesel]

Technically you should never have to, since, according to Ford (and every other manufacturer), the chains and and associated components are "good for the life of the engine". Unfortunately that is typically not the case for just about any overhead cam engine, unless you consider timing chain/chain component failure to be the end of its life. There are 2 different engines shown in this video. The main one (the one outside of the vehicle) showed no signs of any issues at nearly 200,000 miles. The only reason I did them was because I was swapping the engine from one vehicle into another, and it is way easier to replace the stuff outside the car than in it, and the car was going to a friend of mine that is a single mother of 2 kids, with no spare vehicle to drive in the event of a breakdown, so reliability was of utmost importance. The other one (in the vehicle) had a water pump leak at around 180,000 miles, and since the chains have to come off to replace the water pump, might as well replace those as well. On this engine, the chains and all associated components appeared to be in good shape, with no signs of imminent failure. So to answer your question, it's a crap shoot. I really don't have a solid answer. With these engines, it seems that the water pump failing is the biggest concern, and you might as well replace the chains and related parts while you're in there because it is a pain of a job to do. I personally have never seen a timing component failure on one, but that is definitely not to say that it can't or hasn't happened. I wish I could give a decent answer, but unfortunately I can't.

[@darkhorseautoanddiesel]

​​@@Shmish_smorsonIn probably 99% of cases, you are probably right. Unlike the 4.0L SOHC made in the 2000's, they seem to have actually done a decent job designing these chains and components. I'm sure there has been a few chain failures, but I've never had to deal with one. It's pretty much always the stupid water pump.

[@robertbruneau112]

Wow, 200k and the abuse that pump has to endure, and was just now being replaced, pretty good Ford!.... I think Nissan also has the same design, funny how you never hear how stupid they are. oh and Chrysler 2.7 v6 too. Its a great engine, lots of power and reliability, this design keeps monkey's and fiddlers from ruining their family car. Chains should never go on dry, soaked in oil for 24 hrs before assembly.

[@Mariovlogs-pf4jl]

Wow that's a big job how can you tell if it needs timing chains what codes or is it lose

[@darkhorseautoanddiesel]

The most common sign of timing chain issues is a rattle at startup. There can be codes as well, however I don't have a list on hand of what possible codes would indicate failure. However, usually the chains don't fail on these engines. I'm not saying they never fail, because I'm certain there has been failures, but I've personally never seen it. Usually the chains get replaced during a water pump replacement because the chain has to come off just to get to the pump. So since it had to come off, and getting to them is obviously a major job, it recommended to just replace it all while you're in there.
