Why The Ford Coyote Engine Is So Great (But Flawed)

When the 5.0 Coyote engine was designed it was manufactured with a new cylinder head. This first-generation Coyote engine was made from 2011 through 2014.

It was used in Mustang GT and F-150 pickup trucks. As for performance, the intake and exhaust lobes of the camshaft moved in unison, so it was limited in power and efficiency.

The newly remodeled cylinder head was necessary to give the engine the versatility and performance it needed. It was the first new overhead camshaft cylinder head since the 4.6-liter V8.

One of the key differences in the two generations of the Coyote engine was Twin Independent Variable Cam Timing (Ti-VCT).

Here’s How the New Coyote Engine Design Enhanced Performance.

According to MotorTrend.com, the first generation Coyote engines had a basic port fuel injection design, similar to modular engines. The manifold was made from light materials to keep the weight level down and absorb heat. The first-generation engines ran at 420 horsepower at 6,500 rpm.

When the company switched to the Ti-VCT it changed the engine platform. From 2015 through 2017, upgrades were focused on airflow and higher rpm. This new Coyote engine featured larger intake and exhaust valves.

The VCT system was rebuilt to limit camshaft movement and to improve cold-start emissions. The pistons had larger valves as well. Several other minor upgrades improved performance.

The biggest upgrade occurred in 2015 with the addition of charge motion control valves, which were highly advanced over the previous system. It resulted in a better air/fuel combination that offered improved fuel economy and lower emissions.

The second-generation Coyote engine saw horsepower go up to 435 at 6,500 rpm. Torque output increased from 390 to 400 pound-feet, at 4,250 rpm.

Issues With the 5.0 Coyote Engine

No engine is perfect, and the same can be said for Ford engines. According to VehicleHistory.com, here are some of the common issues found in the Ford 5.0 Coyote engine when turbocharged or super-boosted.

  • Oil leaks
  • Ignition coil failure
  • Bad or oil-covered spark plugs
  • Issues with the exhaust gas circulation valve
  • Problems with electronic throttle
  • Vehicles were built without roll pins
  • Transmission issues are common such as slips, rough shifting, and clunks
  • Rough Idling

Even though the engine isn’t perfect, fixing any issues the Coyote engine may have is an easy process.

  1. The Coyote engine does not have an EGR valve and no Coyote engine did not have independent variable valve timing. It was one of the features at introduction in 2010. In fact the independent intake and exhausy variable cam timing is exactly why they were able to skip the EGR system, it does so by retarding the exhaust at the correct time tremendously reducing nitrogen dioxide output with no EGR.

  2. On third motor in my 18 f150.. waiting on a motor which are on backorder. Imo these motors are junk.. no oil on driver side heads.. total engine failure!

    • A few things that I have learned about coyote are that they suffer from oil starvation. First mod after CAI should be oil catch cans on both sides. For whatever reason a CAI on these motors results in instant oil blow by. If you’re not great at keeping your eye on oil consumption, pull the motor and build it the way it should have been built. With a normal coyote, Ford didn’t really go the extra mile on bearings, rods and pistons, springs, valves, and valve train. Under most usage though, should be fine. Start running it harder and doing odds and end modifications which impact air volume in/out, then you better start watching oil consumption. If you don’t, bye bye bearings.
