Gen IV 5.0 Wet-belt driven oil pump and it's consequences?

[PNWTremor]

EDIT: There is already a thread on this here.

Today I discovered that Ford ended the production of chain-driven oil pumps in the 21+ Coyote, and switched to a wet-belt driven oil pump. Mustang guys, you are safe it sounds like. (Source)

With the exception of the 1.0L Eco-boom, other small displacement POS Ford engines, does anyone know of this creating an issue? Do we have any guys with engines replaced under warranty because of this? It's been 5 years since the first 21 5.0 F150 was sold with this tech, so I'd expect at least something to come up. I realize this is not an area people touch on or talk about, maybe that's a good thing.

Does anyone with knowledge on this topic have anything to add?

I don't mind replacing belts/chains, but this one is on the back of the motor by the transmission, makes it a little harder.

Thanks

Mine had 37 thousand miles on it. Never had a single issue of any kind with the truck. I changed oil pretty frequently. One of the best trucks I have ever driven.

I haven’t seen anyone have anything to say about it on here

These belts are becoming more common. Most are rated for 200k miles, or so.

No idea what the Coyote's is rated to.

It’s not on the back of the engine, it’s up front and crank driven. No, there are no known major issues. It seems they last to about 300k miles or so from what I’ve seen online in the 2.7 and LZO. The one in the 1.5 EB came apart due to the tensioner arm system loosening the belt, had nothing to do with the belt itself. The Mustang doesn’t get this because it doesn’t have a deep sump oil pan like the truck application. I’d change it around 150 or 200k if you plan to run it to 300k miles. Not a worry of mine at all.

Yup, you are right about the location. I was looking at the Ford Technical docs incorrectly lol. After reading up and educating myself on the topic of belts, the materials used in them etc --in this case, Kevlar-- I'm not worried about it.

With any luck, our Trucks will make it to 150-200K problem free, at which point there should be enough evidence of it being a failure point or not. Cheers.

Yes, but the service manual has stated to change these belts at 100,000.

This is the reason why I did not buy a 5.0 this time.

Wet belts are a horrible idea. They wear out 2-3 times faster than their dry counterparts despite being made of kevlar and oil resistant materials. When they do start to break apart where do all those chunks of belt end up? The oil pickup screen. Ford has has nothing but problems with them since they started using them. Faced class action lawsuits and forced to repeatedly recall hundreds of thousands of vehicles world wide to repair them. Yet, they continue to use them. Why? Because they are cheaper than chains.

If you buy any vehicle with a wet belt be prepared to not only change the it twice as often as is recommended but also have the oil pan removed to inspect and clean the oil pump pickup screen.

False

It’s really a non issue and oils the engine better than a traditional gerator pump. The 2.7 has used this belt for 7 model years now and there are no mass or even common failures. The fear mongering is silly and I see so much false information posted on it all the time.

This design gets you better oiling for the entire lifetime of the engine as you are now pumping oil from the sump rather than priming way up at the crankshaft. This is healthier for your main bearings, rod bearings, cam journals etc than the old fashioned oil pump. Unless you work for DuPont and make the belt I really don’t weight your opinion much because so far in their 7 years of service they are doing great lol.

With Ford’s track record, especially with the EcoBoost, statistically the 5.0 will last longer than the alternative. No one can deny it, it’s in the writing.

We’ll see who has an issue first:
1. My wet belt
2. Your cam phasers / Turbos

Yeah I agree and I’m not worried about it.

I don't see this in the factory service manual, can you post the page from the manual that contains this information?
