Inside Look | Gen IV Coyote V8 Engine | Livernois Motorsports
There are few things we find more interesting than tearing down a new engine and seeing what changes/upgrades the engineers have made. So when we heard Livernois Motorsports had a pile of F-150 Gen IV Coyote V8s they were disassembling and rebuilding, it was an obvious choice to stop by and check everything out. We left educated and excited to see what’s to come.
Our visit took place in August of 2023, and the Gen IV Coyote had yet to hit the streets in the S650 Mustang. However, a much different version of the Gen IV found its way under the hood of the updated 2023 F-150. The major changes from the very popular Gen III Coyote include; a belt-drive variable vane oil pump, cylinder deactivation, and significantly revised cylinder heads. In the following video we take you along as we explore these changes across several engines in various states of assembly/disassembly. Check it out:
This is the wet-belt driven variable flow oil pump Ford is now using on the F-150 Coyote engines. The Mustang Gen IV retains the traditional crank driven geroter style pump.
That's one complicated cam cap.
These oil feed tubes run through the head and deliver the hydraulic pressure needed to activate the cylinder deactivation system.
This is a better look at the control solenoids for the deactivation system and the mount for the high-pressure fuel pump.
This oil passage (top-rear of the deck surface) supplies the additional oil needed to operate the cylinder deactivation system. The Mustang Coyote retains this feature, which should provide additional oiling to the valvetrain.
A closer look at the new oil galley in the Gen IV block.
The block also now features some additional holes to reduce both weight and windage.
The bottom-end is largely unchanged from the Gen III Coyote.
One of the best features of the Gen IV truck Coyote is the addition of a separate cam carrier plate to remove the cam journals from the head.
