5.0 Coyote Engine Specs 

5.0 Coyote Engine Specs

The 5.0 Coyote is a naturally-aspirated engine, part of Ford’s series of modular engines. Over the years, it has been through a series of updates, resulting in varying specifications and features depending on the specific generation or model:

1. Horsepower 

Ford engines generate massive power, especially high-end cars like the Mustang. Unsurprisingly, the 5.0 Coyote engine packs plenty of horsepowers, making it reliable even under challenging conditions. 

The Gen 1 50 Coyote engine has a horsepower of either 412 (2011 to 2012) or 420 (2013 to 2014) HP. The power is so high that the company has to strengthen the wall.

They did so by creating sturdy webbing instead of thicker material. Meanwhile, the Gen 2 Coyote engine has 435 HP, and the Gen3 has 460 HP.

2. Torque 

Over the years, Ford upgraded the 5.0 Coyote engine’s power production to keep up with the changing demands of its users.

The Gen 1 engine has 390 lb-ft of torque. Gen 2, meanwhile, has 400 lb-ft, and Gen 3 has 420 lb-ft. Along with the increasing horsepower, there were also improvements in torque to deliver more superior performance. 

3. Displacement 

An engine’s displacement is responsible for moving fuel and air, generating power. Coyote engines generate high power like their competitors but with a smaller displacement.

The first and second-generation Coyote engines have a displacement of 4.951 L. Meanwhile, the third generation has a displacement of 5.035 L. 

4. Stroke 

All three generations of the 5.0 Coyote engines have a stroke of 92.7 mm. This specification refers to the distance in the cylinder at which the piston travels. The higher the stroke, the more power an engine can generate. 

5. Bore 

The bore of an engine refers to the diameter of its cylinder. A bigger bore means that an engine will have bigger valves.

In turn, it pushes more air, making it more powerful. Both the first and second-generation 5.0 Coyote engines have a bore size of 92.2 mm. The third generation, meanwhile, is slightly larger at 93 mm. 

6. Compression 

An engine’s compression is its combustion capacity, which is necessary for running the motor. A compression drop can result in power loss, idling, and high fuel consumption, among other problems.

The compression of both the first and second generations are 11:1 and 12:1 for the third generation of the 5.0 Coyote engine. 

Is the 5.0 Coyote Engine Reliable? 

In general, the 5.0 Coyote is a reliable engine. It has been through three generations, showing how Ford is still a preferred choice even with newer alternatives.

Each generation, new features are introduced to make the 5.0 Coyote stand out and deliver reliable performance:

1. Modular Engine 

Top Modular Engine

One of the proofs that the 5.0 Coyote is reliable is its popularity. Many Ford enthusiasts consider it as the company’s top modular engine. Since the 1990s, Ford has made modular engines, including the 4.6 and 5.7 L. The most popular, however, is the 5.0 Coyote. 

Holds the Record for the 1/8-mile Drag Race in 2018

The 5.0 Coyote holds two records, which are also why people love them. It holds the record for the 1/8-mile Drag Race in 2018 through the Modular Motorsports Racing.

The engine achieved a power of 3,500 HP hitting 202.29 seconds in 3.83 seconds. It also holds the ¼-mile Drag Race World Record, wherein it ran 265.43 mph in a 5.67-second pass. 

2. Made Using High-Quality Materials 

Tough Construction

Another reason for the reliability of the 5.0 Coyote engine is its tough construction. It uses high-quality materials to ensure longevity, even in the toughest conditions. With proper care and maintenance, this engine will withstand the test of time without compromising power.

From the fuel injection port to the forged linking rods, all components are built to last. The parts are unrivaled in their class, so you can be confident that the engine will keep up, regardless of the driving environment. 

3. Features Innovative Technologies 

Being a product of years of research and development, the 5.0 Coyote has some of the most advanced technologies you will find in a modular engine.

Twin Independent Variable Camshaft Timing

For instance, it has Twin Independent Variable Camshaft Timing, a significant improvement from the old Variable Camshaft Timing Technology. It allows the engine to produce higher power and torque. 

4. Easy to Modify 

Being a popular modular engine, the reliability of the 5.0 Coyote stems from the fact that it allows easy modification. If there is anything that is not at par with your standards, you have the option to customize the engine as you deem fit. 

Through a Coyote swap, you can provide superior power to old Mustangs and F-150s. It can be an easy DIY task for those with the knowledge, experience, and tools. Nonetheless, if you are not a handyman, it is best left to the pros. 

Again, what is a 5.0 Coyote Engine? Ford Motor made the Coyote Engine, a 5.0 liter (L) naturally aspirated V8 engine for power sports cars, including Ford Mustangs and Ford F-150.

Most Common Problems with the 5.0 Coyote Engine

5.0 coyote engine problems

While the 5.0 Coyote is a reliable engine, it isn’t perfect. Below are some of the most common problems that it can experience:

1. Engine Tick 

One of the most persistent problems in a 5.0 Coyote is engine tick. While it does not significantly impact reliability and performance, some people might find the weird noises annoying. While Ford notes that it is normal, many owners may worry when they hear the engine ticking. 

2. Rough Idling 

It is also common for 5.0 Coyote to idle roughly. Upon starting, the engine may not run smoothly, causing a bit of a shake-up.

Faulty Fuel Pressure Sensor

A potential culprit is the fuel pressure sensor, which might warrant a replacement. The failure to do so early can result in more serious consequences for the engine, which can also be more expensive to repair. 

3. Stalling 

Aside from rough idling, the 5.0 Coyote can also be prone to stalling. This can lead to power loss when you are driving. You can attribute one problem to a dirty throttle body, which you can fix quickly by cleaning such. A bad battery can also be the suspect for engine stalling. 

4. Spark Plug Damage 

While the 5.0 Coyote has several parts, one that is often easily prone to damage is the spark plug. Pay attention to several indicators that it needs repair or replacement, including:

  • Low gas mileage,
  • Rough idling, and
  • Misfiring under load. 

5. Ignition Coil Damage

As with the spark plugs, damage in the ignition coil is also a potential problem in the 5.0 Coyote engine. It is a crucial component of a vehicle’s electric engine management, so it must always be working at its peak.

By running a diagnostic test, you will easily know if the ignition coil is the problem or anything else. 

6. Recirculation Valve Malfunction 

A recirculating gas valve is another issue that is common in a 5.0 Coyote. The gas valve wears out prematurely without proper care and maintenance. Once it has problems, the engine’s performance drastically suffers, harming both power and efficiency. It also increases gas emissions.
