Ford Copies GM's Mistake?!? 2021 Ford F-150 5.0L V8 Oil Pump Change

The 2021 Ford F-150 5.0L V8 has several changes including cylinder deactivation and, now we learn, a wet belt driven oil pump. This is the same idea behind the GM 3.0L Duramax Diesel. Is this oil pump belt on the F-150 5.0L V8 a disaster waiting to happen?

The more i look at some of these newer trucks the more i think I'll just keep what i have.

On the Hemi and GM gas engines that oil pump is driven directly off the crank shaft. The chain is for the camshaft only.

Ford also said the 1L timing belt was to last the life of the motor. Technically correct as when the belt fails the motor is done.

I've seen wet belt use in industrial automation and power transmission for as long as I've been alive. I'm not concerned about the GM belt, or this one for that matter. They last.

[ricks.]

There is no controversy. Ford engineers have state that the belt is a Kevlar reinforced, liquid-cooled belt that is supposed to last the lifetime of the engine and has been tested at over 1100 horsepower in their Dyno testing.
The change in oil capacity was most likely due to Ford's 19-2365TSB which fixes the "oil consumption problems". They found that some F150's had shorter dipsticks which in turn had too much oil in the engine. Also, the new pump is a high volume billet pump.

No matter what vehicle you buy, someone's going to tell you it's junk.

Its almost as if Ford is planning forced obsolescence with the Coyote. They put a belt-driven oil pump AND displacement on demand...BOTH of which nobody asked for. And it seems like this will be an engine-out job if/when it goes. Ford also has the belt-driven timing and oil pump on the JLR/Peugeot diesel. Chains....yes, chains are the way to go(with good tensioner, guides, sprockets and such).

Ford has had belts running in oil since 2014 with the 1.0L EcoBoost engine. On that engine the oil pump belt and the timing belt both run in oil. Now, we didn't sell a bunch of them but up to this point we've seen zero issues with the once we did. I don't expect to see any issues with them.

That F150 belt is a KEVLAR infused belt and has been dyno tested to 1100 HP ! I think it's just fine !!

[NoName-tzji]

The value of my old vehicles just doubled again! Lol

[Jdplayz-bqys]

I feel like Ford refined it better with their new revised engine design. But Ford should do further research on engine durability and protection against elements.

[thankyou]

I don’t think the belt driven oil pump will be a big deal, but time will tell
And the cylinder deactivation doesn’t seem noticeable or mess with the engine so i also think it will be a huge problem either, though disabling it will probably extend the life of the engine a bit more i hope

[noniespam]

That will make me think twice on the 5.0, didn’t hear if you mentioned if Ford requires you to pull the transmission to check the belt.. That is a big deal.

[thankyou]

I have seen a couple of videos on checking the 5.0 oil level on the new f150 and so far it looks like they have solved the problem, though its just too early to say it has completely solved the issue

[kboak]

Crikey! I just switched to Ford and they start this nonsense? I think I should just get an old tractor to drive around.

[hdzez]

Just to clarify, the timing chain only drives the camshafts(and water pump if applicable) from the crankshaft via a chain on the Gen 3 and older Coyote engines, along with most engine designs. The oil pump is driven via gerotor(G-Rotor) style pump gears that are keyed onto the crankshaft snout. It's a very reliable system. Why they decided to go to a belt driven design is anybody's guess. Fuel mileage? Cost savings? Maybe. Anything for one more MPG lol

It’s hilarious how when GM has a belt driven oil pump y’all have a field day, but when Ford does it y’all try justifying and praising them

[AB-coyote]

Coyote V8 has called for 5w20 since day 1 in 2011.

[GlenCoombs-fj]

The previous generation coyotes oil pumps were driven directly off the crankshaft and had minimal failures unless driver induced. The picture you show halfway through the video is also driven off the crankshaft. Know what you are talking about before trying to explain it wrong.

My buddy put a Cummins with mechanical fuel injection in his 2000 manual trans Silverado. The more I see these new developments the more brilliant he becomes in my eyes.
