Ford Ranger Problems

This could be caused by something inside the engine bay rattling or vibrating, but could also be linked to the exhaust system or its heat-shielding doing the same thing. When you hit the accelerator up a hill, the engine and driveline (and exhaust) are suddenly put under a lot of stress which can be passed along any mechanical link or fixture, making things flex or vibrate that don’t normally do so when they aren’t subjected to the same stresses and loads.

When the engine is cold, have a feel around the engine bay to find anything loose or poorly mounted that could contribute to such vibrations. It could be as simple as a poorly located clamp of a loose piece of trunking or internal panelling vibrating against another part. Often these noises will be conveyed into the cabin via the fresh air vents, making them sound even louder.

Just be sure not to confuse a rattle with the normal cacophony of noises a modern turbo-diesel produces as part of operating under load.

There’s a fair bit going on in a Ranger’s all-wheel-drive driveline, so you can expect a bit more noise than that generated by a conventional car. It’s not uncommon, either, for one example of a car to be a bit noisier than another of the same make and model and this is all down to what’s called production tolerances where there might be slight differences in two otherwise identical components.

In the case of driveline noises, it’s often said that a noise is more of a concern when it’s heard all the time, not just at a particular speed or frequency. If the noise goes away below 80km/h and is gone by 90km/h, then it could easily be one of these transient noises that doesn’t signify much to worry about. Concern should set it, however, if these noises, their volume and/or their duration start to change or become more frequent. At that point, you can be pretty sure things are changing inside the driveline and that’s usually an early sign of components starting to wear. Keep and ear on things and if the noises change, have them checked out. If you’re still concerned, have a mechanic who knows these vehicles well take a ride in it at the problem speed and have them compare it with other Rangers.

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.

I can see why the internet cohort might be confused by this question (and why your mate at the pub may or may not know what he’s talking about) because it’s a bit of a weird one. For reasons of friction reduction (efficiency) and reliability, the camshafts in the Ford Bi-turbo are driven by a rubber toothed belt. But – and here’s the strange bit – the belt is partially submerged in the oil in the engine’s sump, so it’s a 'wet' timing belt. While the vast majority of other rubber, toothed timing belts run in a 'dry' environment.

Ford reckons this gives the engine the low noise of a conventional rubber timing belt, combined with the low friction running of a conventional `wet’ timing chain. But the high-strength cords and the oil-resistant rubber the belt is made from, says Ford, also mean that it should last a lot longer than a conventional timing belt. While conventional belts should be changed between 80,000 and 120,000km (roughly speaking) the Ford belt is said to be good for 230,000km.

For the record, the Bi-turbo’s oil pump is driven by a second belt of the same construction.

No, the new Ranger is code-named PY, while the vehicle in question is a PX. Admittedly, it’s a very late-build PX (a Series 3, if you like) which got a revised look and extra tech, but it’s not a 'Next Gen'. The real giveaway is that it has the five-cylinder 3.2-litre engine fitted. This engine was dropped for the newer models, Ford electing to stick with the 2.0-litre bi-turbo and 3.0 V6 diesel engines and the twin-turbo 3.0-litre petrol unit for the Raptor.

Noisy tappets (also known as hydraulic lifters) are relatively common on engines that have done their fair share of work. By using oil pressure generated from the engine’s oil pump, the hydraulic lifter can adjust to maintain the perfect gap between itself and the engine’s intake and exhaust valves. This improves efficiency and reduces engine wear, so it’s an important job.

Over time, the lifters may become a bit lazy (or weak) and may not be able to maintain that correct gap. At which point the extra clearance causes the tapping sound we associate with worn lifters. Replacement is the solution, and best practice says replace them all at once on the basis that if one lifter is already weak, the rest won’t be too clever either.

However, there’s one thing you can try before that, and that is to give the engine an oil change with a high-detergent (as most diesel engine oils are) content oil and a clean filter. Sometimes, fresh oil will clear out a small piece of grit or rubbish that is blocking the oil flow to a lifter and restore it to full health.

While many car-makers now profess that their automatic transmission no longer need regular fluid changes, many mechanics believe there’s no harm in doing so and, in fact, there are benefits in doing so. They include reduced wear over time and the removal of any contaminants that might cause problems. Also, if a transmission has ever reached high temperatures, the fluid should be replaced.

The thing to know is there are two types of fluid change. In the simplest, the transmission fluid is drained, the filter changed and new fluid added. Inevitably, some of the old fluid will remain in the torque converter and other components. But a more complete approach is what’s called a fluid flush where new fluid is pumped through the entire transmission, purging it of all the old fluid. The full flush method is best practice and shouldn’t cost a lot more.

The last decade of dual-cab four-wheel-drive utes have emerged as the tow-vehicles of choice, and you see them everywhere filling roles exactly like the one you have planned. Popular models include the Ford Ranger you’ve nominated, Toyota HiLux, Mazda BT-50, VW Amarok, Mitsubishi Triton, Nissan Navara and Isuzu D-Max. But there are also cheaper alternatives including makes like the South-Korean made Ssangyong and various Chinese brands like LDV and Great Wall.

Just make sure you know exactly how much you need to tow before making a decision as some of the cheaper models don’t have the same outright towing capacity and even if they do, some of them don’t have the engine performance to make towing as easy as it should be. For parts availability, the Toyota would be king in really remote areas, but any of the major brands are pretty well covered in Australia.

Meantime, don’t rule out ute-based wagons such as the Ford Everest, Isuzu MU-X, Mitsubishi Pajero Sport and Toyota Fortuna. These offer better ride comfort when unladen thanks to more sophisticated rear suspensions and most have as much or almost as much towing capacity as their ute brethren.

It’s very unlikely a workshop would replace a component it fitted two years and 25,000km ago for free. Spare parts and repairs come with warranties, but generally not over that period of time or mileage. In any case, it sounds more like the clutch or flywheel has failed, rather than the master or slave clutch cylinders.

This model Ranger had a dual-mass flywheel designed to make for smoother operation, but the design cold also lead to premature clutch wear. When that happened, difficulty in selecting gears was one of the symptoms. Some owners when faced with this problem, converted their vehicles to a conventional single-mass flywheel to get around the problem in the future.
