Ford Ranger 2.5td WL turbo engine
R42,000.00
The Ford Ranger 2.5 TD WL (or WL-T) is a 2.5-litre, 4-cylinder turbocharged diesel engine. Known as a “workhorse,” it was co-developed with Mazda and powered the Ford Ranger / Mazda B-Series (Drifter/Bravo) from roughly 1998 to 2011.
Engine Specifications
The WL-T is a mechanical, indirect-injection engine valued for its simplicity and ruggedness.

| Maximum Torque | 266 Nm @ 2,000 rpm |
| Configuration | Inline 4-cylinder, SOHC, 12 valves (3 per cylinder) |
| Bore x Stroke | 93 mm x 92 mm |
| Compression Ratio | 19.8:1 |
Key Design Features
- Aspiration: Features a conventional turbocharger (often the IHI RHF5) and an intercooler on higher-spec “T” versions.
- Fuel System: Uses a mechanical fuel injection pump (prechamber design) rather than modern common-rail technology. This makes it less sensitive to poor fuel quality but noisier than newer diesels.
- Timing System: Driven by a timing belt that typically requires replacement every 100,000 km.
Common Issues & Maintenance
- Glow Plug Failures: Hard cold starts or smoke on startup often indicate faulty glow plugs or a failing relay.
- Overheating: The WL-T is notorious for cracked cylinder heads if overheated. It is critical to maintain the cooling system and avoid pushing the engine too hard when it’s already running hot.
- Injection Pump Sieve: A common cause of sudden power loss is a clogged sieve (tiny filter) inside the diesel pump inlet.
- Oil Viscosity: Using oil that is too thin can cause excessive diesel knock or injector noise; a 10W-40 or heavier oil is often recommended for older units.
