‘Exploring’ Service Needs On The Ford 4.0L V6 Engine

Rated at a rather anemic 210 horsepower, the 4.0L SOHC V6 is not exactly a high output engine. It also has an unusual overhead cam drive setup.

Click Here to Read More

Unlike most other OHC V6 and V8 engines that drive both overhead cams directly from the crankshaft with a belt or chain, this engine has an intermediate jackshaft in the middle of the block where a pushrod cam would normally be located. the 4.0l sohc engine was found under the hood of many ford and related suvs and light trucks, as well as 2005-’10 mustangs.

A short timing chain on the front of the engine connects the crankshaft to the intermediate jackshaft. A second, longer timing chain behind the first chain connects the front of the jackshaft to the overhead cam on the left side of the engine.

A third timing chain in the back of the engine connects the rear of the jackshaft to the overhead cam in the right cylinder head. There is also a balance shaft in the crankcase of engines used in 4×4 trucks, which is driven by a fourth chain directly off the crankshaft.

Why Ford designed the cam drives this way is anyone’s guess. It probably allowed the engine to be shorter and more compact. But one of the unintended consequences of this fore-and-aft split cam drive arrangement is that it makes the timing chains, guides and tensioners VERY difficult to replace — which makes for an expensive repair when a chain guide or tensioner fails on one of these engines (a common problem on high mileage engines, especially if the owner has ­neglected regular oil changes).

TIMING CHAIN PROBLEMS
Some of the early engines up through 2002 in the Ranger and Explorer have had a timing chain rattle problem due to the poor design of the original teflon chain guides. The noise is most noticeable when a cold engine is first started, and is usually loudest from 2400 to 3000 rpm.

The same noise problem can also develop in 2003 and newer high-mileage engines as a result of chain guide wear. In some instances, the guide may break and disintegrate and spew debris into the oil pan. This may also cause one of the timing chains to break (typically the front left chain).

Fortunately, the 4.0L SOHC is not an interference engine so a timing chain failure won’t bend the valves. But it does create an expensive repair for the vehicle owner.

Ford issued a TSB for the timing rattle problem and released a redesigned “‘cassette”‘ (the timing chain, gears, guide and tensioner assembly) for the left front timing chain. This timing chain cassette can be replaced without having to pull the engine out of the vehicle.

But, if the engine has a bad rear chain or guide, or a chain guide has failed and throws debris into the crankcase, you will have to remove the engine to make the required repairs. That includes removing the flywheel and flexplate so that the rear cam drive cassette can be replaced, and pulling the oil pan so any debris in the oil pan and oil pickup screen can be cleaned out.

You’ll also need a special tool kit (Ford or aftermarket) to hold the cams and tension the timing chains, and to prevent the crankshaft from rotating while you’re doing the cam drives. You’ll also need the proper puller to get the harmonic balancer off the crankshaft. one of the unintended consequences of the 4.0l’s fore-and-aft split cam drive arrangement is that it makes the timing chains, guides and tensioners very difficult to replace and an expensive repair when a chain guide or tensioner fails.  courtesy: cloyes gears

The redesigned Ford primary timing chain service kit includes an improved chain tensioner and chain guide, chain, jackshaft and sprockets. Kit number 2U3Z-6D256-AA is for balance shaft engines in 1999 to 2001 4×4 Explorer/Mountaineer, 2001 to 2002 4×4 Sport/Sport Trac and all 2002 Explorer/Mountaineer (except engine codes 2G-960-AA and 2G-964-AA). Kit number 2U3Z-6D256-BA is for non-balance shaft engines in 1999 to 2001 2WD Explorer/Mountaineer and 2001 to 2002 2WD Sport/Sport Trac, and all 2001 to 2002 Ranger.

ENGINE SERVICE
If the head gasket is leaking, replacing the left head gasket can be done with the engine in the vehicle (assuming there is enough room to pull the head). But if the right head has to come off, the only way to remove the head is with the engine out of the vehicle because of the rear cam drive on the right head.

At this point, some might argue that it’s cheaper and easier to simply find a good used engine and replace the old motor rather than repair it. This might be a viable alternative IF you can find a good used low-mileage 4.0L SOHC V6 that can be swapped into your customer’s vehicle. a short timing chain on the front of the engine connects the crankshaft to the ­intermediate jackshaft.

But by the time many of these engines end up in a salvage yard, they don’t have a lot of miles left in them. A better option if your customer is willing to spend the money would be to install a remanufactured engine. A reman engine from a reputable supplier should be completely reconditioned to original specifications and come with an extended warranty.

Some suppliers offer a three-year or 36,000-mile warranty with their reman engines. That’s a better deal than the 30 day guarantee many salvage yards offer (which doesn’t include labor!).

If the engine in your customer’s vehicle has a timing chain rattle problem, and the engine has less than 100,000 miles on it, doing an oil change and using a light viscosity, pure synthetic oil can sometimes quiet the noise.

The lighter oil will flow to the timing chain more quickly following a cold start and reduce the noise somewhat. However, if the engine has a lot of miles on it (more than 100,000) or changing motor oils makes no difference, replacing the timing chain cassette(s) will likely be necessary to quiet the engine.

As we mentioned earlier, this is a rather involved repair procedure so always refer to the Ford service literature for the step-by-step details. If you try to wing it as you go, you’ll likely be in for some unpleasant surprises along the way.

The jackshaft drive gear and cam drive gear retaining bolts are TTY (torque-to-yield) and should not be reused. If you don’t replace these bolts with new ones, there’s a risk of breakage. The rear jackshaft bolt is also covered by a small circular plug on the back of the engine. It looks like a freeze plug but isn’t.

The front left chain ­tensioner can be tricky to extract because of its close proximity to the thermostat housing and coolant sensors. You may have to remove the thermostat housing if you can’t get the tensioner out with a wrench or deep socket.

The left (front) and right (rear) cam drive cassettes for this engine are different, and the design and quality of the parts can vary depending on the supplier. Some aftermarket suppliers buy their cam drive cassettes from the same original equipment supplier that Ford uses, while others do not. Since this is a labor-intensive repair that should only have to be done once, don’t try to save money on a no-name part. Go with the genuine Ford replacement parts or parts from a quality-brand aftermarket company.

Other “fun” parts to replace on this engine include the heated PCV valve on the back of the left valve cover. It’s out of sight and hard to reach with little clearance between the engine and firewall.

DIAGNOSTICS
If the Check Engine light is on and you’re doing misfire diagnostics on a 2006 and up Explorer, a new scan tool PID that’s available on these ­models is the actual burn time of each individual spark plug. By comparing the spark durations, you can quickly see if a spark plug is fouled or a cylinder has low compression because the burn time for that cylinder will be longer. If you see a cylinder with a shorter burn time, it would tell you that cylinder is running lean or the spark plug gap in that cylinder is worn or set too wide.

On some 2005-’10 Mustangs with automatic transmissions, there can be an annoying vibration at idle, especially when the A/C is on. The problem is not the engine, but an exhaust ­vibration. Ford TSB 05-8-6 says the cure is to install a damper kit to dampen the annoying vibration. The kit is P/N 5R3Z-5F240-A.

MAINTENANCE
The original equipment spark plugs are platinum with a 100,000-mile service interval. Make sure you install the correct replacement plugs because the ones for the 4.0L OHV pushrod engine are shorter and won’t position the electrode the correct distance into the combustion chamber.

Though Ford diehards tend to stick with the original Motorcraft brand spark plugs, any brand of spark plug will work in these engines provided the plug manufacturer has a listing for the engine application. The plug gap is 0.054” on most applications.

The crankcase oil capacity on the 4.0L SOHC V6 is 5 quarts, usually 5W-30 for the older vehicles and 5W-20 for the newer ones. Refer to the vehicle owner’s manual for the recommended viscosity.

What is Timing Chain?

The timing chain is a simple device, but it plays an important role in the function of your car’s engine. A timing chain is an upgraded version of a timing belt, and it’s helpful to think of it like the belt that holds your pants up. It looks nondescript, but if you take it off, everything falls apart. So, here’s how it works. Your car’s crankshaft is connected directly to the pistons. It uses the power generated by the engine to turn the car’s wheels. The camshaft (or camshafts), on the other hand, is responsible for opening and closing the intake and exhaust valves. These valves control the flow of air (and sometimes fuel) into the cylinders and allow exhaust gases to exit. It’s vital that the crankshaft and camshaft have their timing down right, so that the valves open and close at the right time. Otherwise, the air and fuel won’t enter the combustion chamber at the correct time, and the operation will fail. So, that’s where the timing chain comes into play. The timing chain connects the crankshaft to the camshaft, ensuring that the whole system is synchronized. The valves open and close at the right time, the cylinders get the air and gasoline that they need, and everyone is happy. Until the timing chain fails, which can happen over time. Then nobody is happy, and the chain will need to be replaced. That said, timing chains are very durable, and designed to last the full lifetime of your car.

Symptoms of a failing Timing Chain

Check engine warning light comes on

Otherwise known as the pesky little light that you like to pretend doesn’t exist. Look, I get that ignorance is bliss and all, but the check engine warning light exists to, well, warn you when something is off with your engine. A timing chain that is beginning to fail will result in an engine that isn’t running quite right, and that will trigger the check engine warning light.

Engine noise

If you insist on ignoring warning lights, can you at least admit that weird noises coming from your car are important warning signs that shouldn’t be ignored? A timing chain that is loose or damaged will often make a whirring or rattling noise. Noises are your car trying to tell you something. Be a good friend and listen.

Poor engine performance

When the crankshaft and camshaft aren’t properly synchronized, the engine will experience incomplete combustion. That will make the motor run a little funny, and you’ll feel it in your right foot. Acceleration may hesitate, and the car may stutter. You may find yourself without as much power as you’re generally accustomed to, and it may be due to a funky timing chain.

Engine won’t run

I shouldn’t have to tell you this, but if your engine won’t run, it’s often a sign that something is wrong with your car. And by “often” I mean “always.” If the timing chain snaps, the crankshaft and camshafts won’t be synchronized. When that happens, the engine simply won’t run at all. Not ideal, if you’re trying to, you know, drive somewhere.

How urgent is a Timing Chain replacement?

Well, let’s start with the obvious. If your car’s engine won’t run, then a timing chain replacement is pretty urgent, assuming you want to actually use your car.

But if your car does run…well, it’s still extremely urgent. If the timing chain breaks, it can cause the valves to contact the pistons, resulting in extensive engine damage. So, I think you know the answer here. Get it replaced as soon as possible.

Research on Timing Chain for Ford Explorer

You will often see musicians tapping their foot. This may make you wonder if they have a nervous tick or suffer from restless leg syndrome, but actually they are tapping their foot to keep time with the music. Timing is very important in many situations. Some people say timing is everything.

Time is of the essence when it comes to replacing your Ford Explorer timing chain. Wear on your timing chain can cause rough idling, reduced fuel mileage and a general decline in your vehicle's performance. Does your check engine light keep coming on? Are you spending more at the gas pump than you used to? Do the math. These combined factors could point to a sour note -- a faulty timing chain.

How Your Ford Explorer Timing Chain Keeps Time

Since the combustion engine was invented, all engines have contained a timing chain or timing belt. The timing chain is a metal chain that is located within the engine. It needs to be lubricated by oil so everything runs together, like the different instruments that play in harmony in a song. When one of these instruments is off the beat, it throws off the entire composition.

The timing chain is used every time you turn on the engine. It connects the camshaft to the crankshaft and is attached to gears and pulleys that run multiple components. For your engine to properly fire, your Ford Explorer timing chain must rotate smoothly around the gears without hesitating.

Off the Chain: When Timing Chains Break

Over time, the timing chain can stretch which may cause engine skips or misfires. Also be aware that if the timing chain breaks, it can result in chunks of loose metal rolling around in the motor and can cause damage to the engine. A loose timing chain can cause vibrations that emanate from the motor and also a rattling noise as the engine idles. These engine misfires and loud noises are often signs of trouble.

It is recommended that the oil in your car be changed every 4000 to 5000 miles. This is because oil starts to separate as it heats and is exposed to solvents in gas. If the timing chain starts to wear out, small pieces of metal can contaminate the oil. Your mechanic will usually notice this when you go in for an oil change. It is imperative that you heed the warning signs and get your timing chain replaced immediately if you suspect a problem.

CarComplaints.com: Car complaints, car problems and defect information

So irratated with my Ford!! I have wanted a SUV for a long time, I liked the Ford Explorer particularly, I've had a Ford F150 in the past that was a awsome truck, so I figured I would have good luck with that again. I WAS WRONG!! I bought my Explorer not even 3 wks ago and it is in the shop with rear differential problems and timing chain tensioner problems.... I've read enough on this site and other sites to know that there are LOTS of people with the same problem... Someone said on here that Ford has obviously got a problem with their drive train - this makes the damn thing work, you have problems here, and you are in trouble!! Not only do these problems put your truck out of comission, it puts LOTS of money out of your pocket - obviously I'm not rich, or I would have bought a new Lexus SUV instead of a used Ford. This is the thing, there are no recalls on the drive train, but, from everything I have read, there should be. If you would go to this site and post your complaints, maybe we can get Ford backed into a corner where they have to acknowledge these problems... I know that there are a few people on here that have done this already, but, unfortunately just a few of us can't get much accomplished. Please take 5 min - no more time than it took you to post your problems on here - and go to www.safercar.com and place a complaint on their site, if we ALL do this, maybe we can get something done. In the mean time we are all screwed with crappy drive trains that are repeatedly breaking and causing us costly problems!! This sucks, I'm so damn disappointed that I don't know what to do!! Please help me make Ford do something about this!!!
