An explanation of what all this means to the uninitiated would be appreciated. 👍

Even the initiated are getting lost.

Cams are chain, only likely service item would be tensioner. That is the good bit. No cam belt to fail and write off the engine.

The oil pump is unusually a small belt in oil, probably a lower friction thing, but obviously could fail and cause oil starvation. But this should immediately bring up low oil pressure warning before any mechanical damage.

The rest of the serpentine belt is water pump, air con, alternator . .

Isn't that the 1.5 naturally aspirated dragon engine?

I have never heard of a oil pump belt failure in these "Dragon" engines.

People confuse these ecoboost with the 1.0 ecoboost which is famed for failure. And that's only down to poor servicing or incorrect oil. My own 2015 1.0 Courier van is now nearly 70k miles with a stage 2 map and it hasn't ecoboomed.

My mate works at a Ford dealer service centre that repairs car for 3 main dealers and said they replace more 2.3 ecoboost engines in the RS Focus than MK8 STs.
