How many kilometres is the turbo-diesel in a 2012 Ford Ranger good for?

Answered by CarsGuide

This is one of those questions where there are no hard and fast answers. The lifespan of pretty much any automotive engine will be determined far more by the way it’s been used and maintained than any rule of thumb being tossed around the industry.

Vehicles that do mainly highway kilometres tend to last longer since the engine is under less stress than one idling in traffic and then accelerating from every traffic light. The same goes for vehicles that have never had a tow-bar fitted versus one that has hauled a three-tonne trailer every day of its life.

Servicing plays a huge part, too, and a well maintained engine will always outlast one that has had skipped oil changes and other preventative maintenance. Overall, diesels used to live longer than their petrol equivalents, but the extent to which modern turbo-diesels are tuned to deliver power and torque means that’s not always the case these days.

Over the years, we’ve seen these Ranger engines fail at mileages as low as 100,000km, while others make it to 300,000 or even 400,000km while still in good health. Common engine problems to watch out for with this model Ranger engines include failed EGR coolers, contaminated and even blocked inlet tracts, worn turbochargers, DPF problems and failures, leaking and faulty fuel injectors and coolant leaks.
