5.4L Water Jacket Question
 

Are there coolant plugs on the block that permit all the coolant to be drained from a 2001 5.4L engine? I'm thinking about switching to NPG+

Hi Beastrider

I clicked on link you made, got stuck there for 1 hr. geez! :D

Interesting...may or maynot need mods. to use NPG?

Anyhow, there should be 2 engine block drain plugs, one on each lower side of block... sq. head...you should see them..look closely as other parts may block clear view.

Good luck...OT :)
