2005 Ford Explorer Sport - Engine options

I have a good trk 78000 org mi.but timming belts jumped put a valve through valve cover.I do not want to put the 4.0 to replace it. ies there another motor that will go in it without a big hassle?

2005 Ford Explorer 4.0 SOHC engine doesn’t have a timing belt.

The 4.0 SOHC is a dependable engine, They regularly go over 300,000 miles unless you don’t change the oil every 5000 miles.

If you don’t change the oil you risk failure of the timing chain tensioner and timing chain guides,

and you now know the rest.

Swapping in a different engine is a hassle. the 4.6 is your only option.
You will need a complete 4.6 and transmission from an Explorer, Complete engine wiring harness for the 4.6, the ECU for the 4.6.

Then after you have swapped everything in, you’ll need to have it towed to the Ford dealer so they can program your keys and anti theft system (PATS) to the 4.6’s computer.


And on a 2005 Ford, I’d question whether the expense of putting in a 4.6 V8 would exceed the value of the vehicle. But to each his own…
