Internal Water-pump Question

[Skwerlee]

From what I've read the earlier generations of the Ford Edge seem to be the ones that have more issues with a catastrophic water-pump failure taking the engine out. I understand that after around 2011 the water-pumps went to a double sprocket setup and are less prone to the types of failures that dump coolant into the oil pan.

 

Is this correct? I just bought a 2017 and I'm trying to learn as much as i can to see if i should invest in a Ford Protect ESP.

 

thanks,

You're correct.  For 2012 and beyond there's a double chain and more robust gaskets/sealing.  There have been few reports of 3.5L water pump failure in the Gen2 Edge but whether that's because of the improvements, generally lower mileage so far or better informed owners (who are now more proactive with coolant changes) nobody seems to know.....unless it's Ford's engineers and they're not talkin'.

thanks for the info!

2011-18 3.5/3.7 engines on the Edge/MKX platform do indeed have the updated timing setup, since the engines are now Ti-VCT i.e. BOTH intake and exhaust cams are variable.  Compared to 2007-10 engines being VCT i.e. only the intake cams being variable.
