Mazda BT-50 2013 Q&As

Check out real-world situations relating to the Mazda BT-50 2013 here, particularly what our experts have to say about them.

• Circuit issues on 2013 Mazda BT-50 fuel injector

  An open circuit on a fuel injector is usually caused by either a broken wire to the injector, a loose terminal somewhere in the electrical circuit that drives the injector or a burned-out coil in the injector itself.

  Changing the suspect injector will tell you if the coil is the problem, but if that doesn’t fix it, you’ve got to work backwards from the injector until you find the fault. Bear in mind that if the injector itself is at fault, the other three injectors might be ready to go out in sympathy. Modern common-rail engines can be hard on injectors and they sometimes need replacing before they’ve done 100,000km.

• Steering locking up in my 2013 Mazda BT-50

  Rather than the steering completely locking up, it’s more likely you’re feeling steering that has lost is power-assistance. It can make the wheel extremely heavy and could feel as though the car won’t steer at all. This is linked to the engine stalling, because the power-steering on this vehicle is driven by a belt from the engine. No engine means no power-assistance.

  The other questions, of course, are why is the engine stalling and why only on left-hand turns. There are plenty of things that can cause a modern engine to stall from a dirty fuel filter to a blocked injector or an electronic fault. And about a million things in between. An electronic scan of the vehicle might throw up a fault code that will help a mechanic unravel what’s going on.

• There is no option for car heating in my 2013 Mazda BT-50

  I can assure you the 2013 BT-50 was, indeed, engineered with a heater and this came standard with any BT-50. The dial that controls the coldness of the air-conditioning is the same one that controls the heating. Turn the dial all the way clockwise and you should have warm air entering the cabin through the various vents.

  If not, then I'd suggest that a previous owner has blocked off the car's coolant supply to the heater core by rerouting the plumbing so the hot engine coolant no longer enters the heat exchanger in the cabin. This was probably done because the heat exchanger was leaking and this was a quick way to stop the leak and keep the vehicle operational, albeit without a heater. It's one of the oldest tricks in the used-car book.

  The best bet is to take the car to a radiator specialist who will be able to figure out what has been removed or bypassed and reinstate the necessary hardware so that your car is heated once again.

• Drivetrain and acceleration problems in my 2013 Mazda BT-50

  The clue here might be in the fact that this problem occurs when you drive slowly for an extended distance. This could suggest that something (engine or transmission perhaps) is becoming hot and the vehicle is switching to limp-home mode to avoid damaging any components. Also, it could be a dodgy sensor which is simply making the vehicle 'think' it's getting hot.

  It sounds counter-intuitive, but driving slowly can lead to overheating as there's less air flowing over the radiator and/or oil coolers to whisk temperature away. When you stop the car and re-start it, the on-board computer goes back to its default settings and away you go again until the sensors detect more heat build-up.

  With that in mind, I'd be checking the radiators and oil coolers for a build up of dust, mud, leaves and other rubbish which could be blocking airflow. But before you start replacing sensors and other components, have the car scanned (by a mechanic) to see if any fault codes make themselves apparent.
