It shoudn't be too hard if it is like my 1996 Explorer 5L V8. On top
of the engine in the front.
Beware that my bypass hose had different diameters at the thermostat
housing and at the water pump. They are now available at AutoZone.
You may have to cut an end to size. The belt may be in the way, but I
did mine without letting the tension off of the belt. I also replaced
the upper and lower hose and replaced the antifreeze at the same time
since I was working on the cooling system and was going to get dirty
anyway.
Thanks.
