2.7 Oil pump belt

[TourGuide]

I love my 2.7 for what it is and how much fun I get out of it.  The more I learn about the oil pump belt in these engines the more concerned I get.  I am putting a link here to a teardown video of another Ford engine - the 3 cyl. 1.5 with the same style belt at 70k.  

 

Teardown video.

 

 

The condition of this belt, at that mileage is - well - verification of the problem I think.

Can you confirm that the 2.7L V6 in the Ford Edge has a belt driven oil pump.

A little research confirms that the 2019 ST and onwards use the belt driven oil pump.

Do we have any idea on how these are holding up? - haven't heard of any reports on this forum, but that could be that there would be very few at 100K miles or more.

The only way to get a visual on this belt is to drop the oil pan, or disassemble the entire front of the engine. 

 

This video IS an example of an engine that had maintenance neglected - the concern is clearly the mileage of this engine.  I look at this video and think - crap - MY engine has 80k on the clock.  I was planning to go to 100k before doing a timing set and replace this belt then.

What's behind your thoughts of changing the timing chain around 100K?

 

I've got 117,000 miles on my 2016 2.7L and don't have plans to change the timing chain, but might reconsider that depending on what I hear back from you.

The chain guides system as well as the chain itself are all wear items to a degree (moving parts).  In addition to changing out that oil pump belt - which in my case is the main motivation personally - changing out those items ensures that this engine goes the distance for me as I plan to drive this vehicle as far as it will take me.  It is a big job since the entire front of the engine comes off - so preventative maintenance I guess is the ultimate goal. 

 

My economic assessment is that it is cheaper to maintain/repair than buy new these days.  I'll see - maybe someone will arrive on the scene with an EV that is reasonably priced - don't laugh - it could happen....

Do you plan on replacing the timing chain sprockets as well?  I'm used to the motorcycle world for when you replace your rear chain, you should replace the sprockets too so that you don't cause premature wear on the new chain.

If I end up going for this repair and the car has lasted that long trouble free - I would do the sprockets too.  The labor involved in taking the front of the motor apart would almost make skipping that step silly I think.

It's great that you're enjoying the 2.7, but your concern is valid — the oil pump belt design in these engines has raised reliability questions. That teardown at 70k really highlights how early wear can become a serious issue if left unchecked. Regular inspection or early replacement might be a smart move for peace of mind.

Everyone is making a big deal out of this because of one tear-down video of a 2.7 that was run without oil, that consequently spun a bearing, which destroyed the engine. Although cracked (from excess heat and lack of oil), the belt was still doing it's thing. These belts will easily do 200,000 miles if the oil is changed on a regular basis with a quality oil of the correct specification.

I worry about the geopolitical state of the world, not when or if my oil pump belt is going to fail.

My lawnmower has a belt driven overhead camshaft running in engine oil - bought 11 years ago and still going strong - makes me think belts in oil isn't a real issue.
