A bad timing belt or timing chain can be a serious issue. If it jumps a tooth, or breaks entirely it can lead to permanent engine damage. It’s important to know the symptoms of a bad timing belt or chain, so this doesn’t happen to your Ford F150.
Timing belts are made out of rubber and nylon, unlike a timing chain which looks a lot like a bicycle chain. Here’s more on a timing chain vs a timing belt. For all intents and purposes, they create the same symptoms when they go bad.
Timing belts are not that common. You’re much more likely to find a timing chain in cars and trucks than belts. Smaller cars, particularly Japanese made ones, can use timing belts instead of a timing chain. They are most commonly found on four cylinder engines.
Ford F150: Bad Timing Belt/Chain Symptoms
Here are some of the most common signs of a bad timing belt on the Ford F150:
- Engine Won’t Start– If your F150’s timing chain or belt has fallen off completely, broken, or has jumped a few teeth, it is entirely possible that the engine won’t even start. You might hear it slapping around as the engine cranks over. If this is the case, the damage is already done.
- Noise– A good indication that a timing belt has gone bad is going to be noise. There may be a sound of rubber beating against something. It’ll typically be a rough rattling sound, and it is often most noticeable right when you start up your F150.
- Performance Decrease– If the timing belt has jumped a few teeth, but hasn’t fallen or broken off yet, it can knock the engine out of time. The timing belt is responsible for keeping the camshaft(s) in sync with the crankshaft. If the timing belt has moved, that means that the valves will open and close at the wrong time. This will lead to a performance decrease. It’s highly likely that the engine is going to be misfiring as well.
- Loss of Fuel Mileage– Fuel mileage will suffer when the engine is no longer kept in time.
- Glazing and Dry-rot (Timing Belt Only)– If you are looking at the F150’s timing belt itself, check to see if the belt is glossy. It should grip your finger as you lightly brush across it. If it is slippery and dry, that is a great indication it could be bad as well.
- Check Engine Light– If the timing chain or belt needs replaced due to wear, but hasn’t jumped a tooth, the service engine soon light will not come on. But, if it has jumped, the check engine light will very likely come on. At the least, you should get some sort of misfire relate codes.
Don’t Overlook the Tensioner
The timing tensioner can also go bad. The tensioners job is to keep the right amount of pressure on your Ford F150’s timing belt or chain. As the belt/chain stretches through normal operation, it would get loose and fall off or jump. The tensioner keeps this from happening by keeping a consistent amount of force on the belt. So, as the belt stretches it adjusts for this stretching. If the tensioner is no longer keeping enough pressure on the timing belt, it’ll cause it to fail.
If you are going to replace the tensioner, make sure to swap the belt as well. It’s so hard to get to, and timing belts/chains are relatively affordable. It’s just the TIME that it would take you or your mechanic to get to it that’s the problem.
Conclusion: Ford F150 Timing Chain Symptoms
Most manufacturers will recommend changing the timing belt at 60k or 100k miles. There isn’t usually a service window at all for the chains. Although, it can vary. Where a lot of people get into trouble is when they buy a used car with 100k no realizing that the belt service is going to be immediately due.
Good luck with your F150. If there is anything that you would like to add, please leave a comment below. We would appreciate it.
Does a Ford F-150 Have a Timing Belt or Chain?
Timing belt or chain plays a vital role in the functioning of a Ford F-150 engine by regulating its valves and piston movement and allowing proper airflow at an accurate time.
Does a Ford F-150 Have a Timing Belt or Chain? The presence of a Timing belt or chain in Ford F-150 engine assembly depends upon its model and manufacturing year. The timing belt plays a vital role in the accurate functioning of the cam and crankshaft. The timing chain also controls the time duration for the opening and closing of each intake and exhaust stroke of the engine’s cylinder.
The timing belt or chain is a part of the truck’s internal engine that connects the crankshaft with the camshaft and ensures that the engine’s valve opens and closes at an accurate time during each intake and exhaust stroke of the cylinder.
The timing belt in Ford F150 synchronizes the crankshaft and camshaft rotation and prevents the engine from malfunctioning.
The timing belt is a band of solid rubber that contains notches on its internal surface, similar to the gear’s teeth.
On the other hand, the timing chain is a continuous metal chain that attaches the camshaft with crank sprockets.
The older models of the Ford F-150 contain a timing belt usually present outside of the engine assembly. Due to this reason, they become more exposed to harmful elements and start to degrade with time.
The models of F-150 that comes into the market after 2007 contain a timing chain in its engine assembly.
The metal chain of timing survives longer and has more durability due to its precise configuration and the ability to receive continuous lubrication from the engine oil like other parts of the engine.
When should the timing belt be replaced on a Ford F150?
Timing belts need to replace much quicker than the timing chain. The robust construction of the timing chain can easily last with the engine’s life unless they do not receive good quality engine oil per their requirement, resulting in its malfunctioning.
Other the other hand, the rubber belt starts to get damaged with leaked coolant, age, and leaked engine oil. As a result, its reinforcing cords become weak and lose their tensile strength that is extremely dangerous for your engine.
The belt failures occur with no warning; you need to find the replacement date in its Owner manual for this reason.
Most manufacturers of Ford F-150 recommend that you can replace your vehicle’s timing belts anywhere between 60,000 miles to 110,000 miles.
Different symptoms can indicate that your vehicle needs a timing belt or chain replacement.
The engine pulleys connect the timing belt with the crank and camshaft. The crankshaft supplies power towards the connecting rods that connect with the pistons present on the engine’s combustion chamber.
On the other hand, the camshaft operates the rocker arm assembly and cylinder valves that send fuels inside the combustion chamber and eliminate burnt gases with the help of the exhaust manifold.
The presence of low oil pressure inside the engine can badly affect your timing belt and cause ticking noise in it.
You can resolve this problem by checking the level of your truck’s engine oil.
If the engine oil level is within normal range, you need to consult with a mechanic to inspect the timing as soon as possible.
The ignorance of timing belt replacement can result in broken valves and pistons, damaged cylinder head, and camshaft, which results in engine failure.
The engine starts to misfire
The fire rate of the engine can easily disturb due to a worn-out timing chain or belt. Sometimes, this belt slips from its location on the camshaft drive that operates the cylinder head valve. As a result, the cylinder starts to open and close quicker than its appropriate time.
In the case of the timing chain, the chain begins to stretch over after some time and skip gears on the cam and crankshaft; as a result, the engine runs out of its timing calibration that can lead to misfire and low accelerating power.
Engine fails to ignite
When you turn the ignition ON, the starter motor of the Ford F-150 starts to operate well, but the engine fails to turn over due to its damaged timing chain that runs its cam and crankshaft.
The broken belt can decrease the engine’s compression ratio and damage its internal compartments like the crank bearings, oil pump present inside the oil pan, cylinder head hardware like the rocker arm, and the pushrods.
During driving, the cracked timing belt can severely damage the pistons due to their direct contact with valves. As a consequence, the valve starts to bend and break different other parts of the engine.
The rough driving of the truck indicates that your timing belt starts to get loose or damage.
You need to consult with a certified professional who can examine all the supporting components of the engine.
Leakage of engine oil
The leakage of engine oil from the timing cover can prematurely damage the timing belt and cause overheating in the engine assembly.
The improper sealing of cover due to loose nuts and bolts and cracked or poorly installed gasket present between the engine and timing cover can cause excessive oil leakage.
The automobile manufacturers suggest changing your vehicle’s engine oil and filter after covering the distance of 3000 to 5000 miles.
If the timing chain starts to wear out, small metal pieces can easily observe on the oil pan.
The certified professional can notice these metal shaving in the drained oil and filter and recommend changing your timing chain as soon as possible.
Other possible reasons for metal shaving in the drained engine oil are wearing cylinder head valves, keepers, and retainers, indicating that it starts to deteriorate and needs immediate replacement.
Engine light flashing on the instrumental panel
The indication of engine light on the truck’s instrumental panel can predict various issues i-e the failing of the timing chain is one of them.
The truck’s computer can determine the source of the problem and show warning signs on the instrumental panel that must be scanned and verified with trouble codes.
The stretch chain can disturb the engine’s functioning and increase its emission capabilities due to this problem; the engine light turns ON. Therefore, it is essential to find diagnostic trouble codes and make necessary arrangements according to them.
In normal conditions, the truck engine has a smooth sound that indicates that everything present inside its assembly is working accurately.
When the timing chain starts to get loose, it creates vibrations inside the engine motor and produces rattling noise even when the engine is idle.
The breakage of this chain seizes the engine assembly and imposes heavy expenses on its owner that can stop by performing regular inspections and scheduled replacements.
How much does it cost to replace a timing chain on a Ford F150?
The replacement of a timing chain or belt is a critical process that requires a lot of time and expense.
The replacement cost of this process depends on the number of labor hours and the price of timing parts.
The price of timing belt parts ranges from as little to as $65 to as high as $140. On the other hand, the labor cost of this process varies from approximately $1000 to $1300.

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.
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.Get a Quote 1-Year | 12,000-Mile Warranty
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.

When Should You Change the Timing Belt in a Ford?
Ford recommends that you replace the timing belt at 60,000 miles for almost all of its models.
A timing belt, timing chain, or cambelt is a part of an internal combustion engine that synchronizes the rotation of the crankshaft and the camshaft(s) so that the engine’s valves open and close at the proper times during each cylinder’s intake and exhaust strokes. In an interference engine the timing belt or chain is also critical to preventing the piston from striking the valves. A timing belt is usually a toothed belt—a drive belt with teeth on the inside surface. A timing chain is a roller chain.
A damaged timing belt needs to be replaced ahead of schedule because it interferes with the operation of the car’s engine. If a timing belt becomes worn or jumps a tooth on the sprocket it rides on, the car’s engine may stall or the vehicle may be slow to accelerate. Even a relatively small collision can be enough to knock the timing belt out of sync.
Symptoms of a Bad or Failing Timing Belt
Common signs include a ticking noise coming from the engine, an engine that won’t turn over, engine misfires, and oil leaking in front of the motor.
