The 3.0L is a great engine…
but like anything, it’s got its weak spots.
At 1E Diesel, we know these trucks inside and out.
We’ve built a package to help keep yours running strong —
whether you tow daily or just drive it to work.
Less problems. More reliability.
No getting stuck on the side of the road.
