Vehicle Compatibility The Ford 2.5 WL non-turbo engine is a direct replacement for various rear-wheel drive (4×2) and four-wheel drive (4×4) pickup trucks produced between 1998 and 2007:

• Ford: Ranger 2.5 D / 4×4 (ER, EQ, R series), Courier 2.5 D

• Mazda: B-Series B2500 / Bounty 2.5 D

(Note: Ensure your current setup is non-turbo, as this naturally aspirated WL engine differs in intake manifolds, exhaust setups, and compression from the turbocharged WL-T variant.)

Recommended Maintenance & Technical Guidelines

• Oil Specification: Requires high-grade diesel engine oil meeting 15W-40 or 10W-40 mineral or semi-synthetic specifications to keep internal components lubricated and wear-free.

• Preventative Care: Regular timing belt replacements, routine oil and filter changes, and keeping the fuel filter free of water contamination ensure maximum service life and uninterrupted operation
