Ford F-150 10th Generation (1997-2003)

1997–2003 · PN96 · truck

The PN96-platform F-150 introduced the Modular Triton V8 family (4.6L 2V and 5.4L 2V) alongside the carryover 4.2L Essex V6. Body-on-frame, available in Regular Cab, SuperCab, and the first F-150 Crew Cab (4-door) from 2001. The split with heavy-duty F-Series began here - F-250/F-350 became the dedicated Super Duty line from 1999.

Watch out: Spark plug ejection on the 4.6L 2V and 5.4L 2V Triton engines is the defining issue - too few threads in the aluminum cylinder head let plugs work loose and blow out, typically between 60-100k miles. Ford issued TSB 07-21-2 acknowledging the problem and authorizing thread-insert repair (the Time-Sert / Big-Sert fix). Owner reports also flag intake-manifold coolant crossover cracks on the 4.6L 2V (same plastic-intake issue as the Crown Vic / Grand Marquis).
