Is it common for a 2019 Mazda BT-50 or Ford Ranger to blow a motor due to a faulty oil pump?
We have heard some reports of Ranger and BT-50 (they're the same vehicle mechanically) suffering oil pump failures with fairly terminal results for the rest of the engine. The other quirk with this engine is that you can't drain the engine of oil and leave it for any more than a few minutes without the pump running dry and needing to be primed before the engine is started.
Not all mechanics know this and many a Ranger or BT-50 engine has been destroyed when the oil has been dropped from the sump and the mechanic has gone to make a cup of tea or do some paperwork. They return half an hour later, replace the sump plug, fill the engine with oil and start it up. But because the pump hasn't primed, there's effectively no oil pressure and the engine is reduced to scrap in a few short seconds.
The problem is partly to do with the different design of the pump and there are even companies that have engineered more conventional oil pumps to replace the standard units on these engines.
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.
Indicator and speedometer issues in a 2010 Mazda BT-50
Modern vehicles have lots of electronics that operate functions such as the dashboard and warning lights. If the car is showing a 4WD light when it's not actually in 4WD, then there's an electrical glitch somewhere in the system.
But the fact that it occurs in tandem with a second fault (the incorrect speedo reading) makes us wonder if you're not looking at something as fundamental as a bad earth somewhere on the car. Electricity can't flow if the circuit isn't earthed, and this is a common source of problems like the one you're seeing. A good auto electrician should be able to sort both problems with simple test gear. If not, a scan of the vehicle's systems may throw up the answer.
