Ford Ranger Engine Problems

Are you having problems with the engine of your Ford Ranger? Let our team of motoring experts keep you up to date with all of the latest Ford Ranger engine issues & faults. We have answered all of the most frequently asked questions relating to problems with the Ford Ranger engine.

Is a blown cylinder in my 2017 Ford Ranger Wildtrak covered under warranty?

Unfortunately, because your car was delivered before May 1 2018, it's only covered by Ford's three-year warranty, which, of course, has expired. New Fords delivered after that 2018 cut-off were covered by an longer, five-year warranty, but that's not much use to you.

The best thing you can do is tackle Ford Australia's customer service department to see if they're open to covering part of the cost of repairs on a pro-rata basis. This is a sometimes a possibility if the vehicle is only just out of warranty or has covered very low kilometres with a full service history. But in your case, I wouldn't be holding my breath.

My 2011 Ford Ranger has lost power after overheating

By connecting the Ranger to a diagnostic computer, you should be able to work out what's constricting the engine power. Modern engines constantly monitor everything from boost pressure to fuel pressure, and transmission temperature to alternator output. Somewhere in those hundreds of parameters will be the problem and it should be fairly obvious to somebody who knows how to interpret the codes the car's computer will spit out.

Meantime, it could be that the engine's installation skipped hooking up a sensor or piece of wiring and that has caused the engine to go into limp-home mode which limits the power the car will produce in the interests of self preservation. On a really simple level, have you checked that all the turbocharger's plumbing is intact and the joints are tight post engine installation? Loose plumbing joints and cracked or split plastic tubing are a common way to lose turbo-boost pressure.

Does a 2010 Ford Ranger XL have a timing belt or chain?

Ford's popular PX Ranger (sold from 2011 until its replacement in 2022) marked a distinct move away from timing belt technology, but prior to that, the Mazda-sourced engine in your vehicle uses a rubber toothed timing belt. As such, this belt and its tensioners and idlers require replacement at regular intervals.

The recommended belt-change interval for this engine is 120,000km or six years, whichever comes first.

Is it a waste of money buying a diesel Ford Ranger or Everest if electric models are coming?

There's been plenty of talk in recent years about the future of diesel engines in vehicles like the Ranger and Everest. And while there's a school of thought that suggests that they'll switch to petrol and petrol-electric hybrid drivelines, that hardly makes a diesel-engined version a dinosaur overnight. Take the Toyota Corolla, for instance: While the latest Corolla is available with a hybrid powertrain (and it's a very popular format) there are still plenty of people happily driving around in their 20-year-old Corollas with conventional drivelines.

The point being that progress is a fact of life. Every time a new piece of tech arrives that is seen as an improvement, car-makers will adopt it. Which means the previous technology is out of date, but not necessarily beyond its useful life.

If you think a plug-in hybrid Ranger or Everest would suit you, then by all means wait until 2024 (the rumoured launch date). But bear in mind that, by then, there may be talk of the next big thing in Rangers and Everests; an advance that could make even the plug-in hybrid look a bit yesterday.

I'm experiencing rpm fluctuation in my 2015 Ford Ranger

It's definitely worth looking into as it's not normal behaviour for the Ranger and could point to a problem that, if not fixed now, could lead to a bigger drama down the track. A scan of the entire vehicle's electronics might show up a problem with the fuel system or throttle set-up. While it's tempting to look at the engine itself as the source of the revs flaring, don't rule out the transmission, either. A faulty torque converter or even a low transmission-fluid level could be the culprit here.

Acceleration problems with a 2008 Ford Ranger

This sounds very much like a fuelling problem. Since a diesel engine has no ignition system (beyond its own compression) any fall off in performance can often be traced back to the fuel system.

The best bet is to take the vehicle to a diesel specialist that knows this make and model and will have either seen this exact set of symptoms before or will be able to make a logical diagnosis rather than just changing random parts that may or may not be the cause of the problem. Things that are likely causes, however, are the fuel filtering system, fuel pump and injectors. But don’t rule out something simple like a bad batch of fuel that is playing havoc with the entire system.

Does the 2014 Ford Ranger have a variable-voltage alternator?

That model Ranger does, indeed, have what’s called a variable-voltage or `smart’ alternator. The idea is that when the car’s main battery is fully charged, the alternator reduces its workload to save fuel. But the reality is that the system doesn’t always recognise that accessories (like a second battery) have been fitted to the car. If that happens, the alternator doesn’t always make enough power to keep accessories like that second battery system fully charged. Which means that suddenly, your car-fridge won’t run overnight.

The good news is that this smart function is purely electronically controlled, and a Ford dealer can disable it for you, returning the alternator to conventional operation.

Is a C-TEK battery charger the best option for protecting the battery in my 2021 Ford Ranger?

The C-TEK brand has a huge reputation for performance and safety. I've personally had such a charger for more than 20 years which has been in use almost every single day of that time and still works perfectly. They're more expensive than some chargers, but the inbuilt protections against incorrect connection and overheating are worth the price, not to mention that longevity.

Some mechanics recommend connecting the two leads from the charger directly to the battery terminals, but conventional wisdom says that connecting the red cable to the positive terminal first and then the black cable to an earth somewhere in the engine bay is a better idea. This method means less chance of a spark igniting gasses emitted by the battery as it charges and discharges.

The indicator lights on the C-TEK unit will tell you when you've achieved a good connection. Using a metal part of the car for the negative attachment point works because the whole car is essentially one big negative terminal. Just make sure your attachment point isn't painted or coated with a chemical that prevents the flow of current. Or that it's not a plastic part (increasingly common these days). Many cars have a dedicated post or connection point within the engine bay.

Why does my 2015 Ford Ranger cut out for no reason?

It sounds very much like a computer problem rather than a hardware issue. When you switch the engine off and then back on again, you’re actually rebooting the on-board computer. I’d be trying a replacement ECU module (borrowed from another Ranger) to see if that fixes the problem. The problem is that because the reboot fixes the issue (temporarily) it might also re-set the computer’s memory, meaning it can’t `remember’ what went wrong and, therefore, won’t offer up the correct fault codes when you scan it. That said, I’d definitely give it a scan and see what pops up.
