Mazda CX-5 Q&As

Check out real-world situations relating to the Mazda CX-5 here, particularly what our experts have to say about them.

• Does the Mazda CX-5 have a timing belt or chain?

  Looking at the popular CX-5 range from 2017 onwards, is the Mazda CX-5 timing belt or chain driven?

  There was a big range of engines used in this model CX-5, but the short answer is a very simple one. It doesn’t matter whether your CX-5 has the 2.0 or 2.5-litre (turbo or non-turbo) or even the turbo-diesel engine option, the engine uses a maintenance-free timing chain rather than a rubber toothed belt.

  That means, you don’t need to even think about the timing chain, because it should last the life of the engine. A timing belt, meanwhile, needs regular replacement to avoid doing expensive damage to the engine if it should break while the engine was running.

• Which mid-size, diesel SUV should I buy?

  Mazda’s SUV range (CX-5 and CX-8) are popular with their owners and have a good reputation in the trade. Crucially, they’re also available with a turbo-diesel engine, so they fit your criteria on that basis. We’d also suggest you take a good look at the South Korean brands’ offerings (Hyundai and Kia) as these are also highly rated by the trade and those companies have been involved with small-capacity diesel engines for decades, so the technology is pretty well sorted.

  It’s interesting that you’ve had a good run from your Holden Captiva as that is far from the experience of many owners and former owners of this particular vehicle. As the Captiva ages it is very likely to start giving trouble, so the best advice is to trade up to a newer vehicle sooner rather than later.

• Will the stop/start function damage the turbo in my Mazda CX-5?

  The advice to always idle a hot turbocharged engine down was based on a period in time when turbochargers didn’t have the water-cooled bearings they do now. With modern turbos such as the one in your Mazda, the bearing shouldn’t get hot enough to need idling down (cooling gradually while the engine idles, pumping oil through the turbo bearing).

  That said, I would imagine that the Mazda’s engine management software incorporates a line of code that will not allow the stop/start function to operate if the engine was at a high enough temperature that anything (turbo included) might be damaged by shutting the engine down suddenly. That same logic also ensures that the stop/start is disabled if the battery is low on charge, if the air-conditioner is running flat out or any other condition exists that requires the engine to be running. If you’re still concerned, you could always disable the stop/start function manually when you come to a stop after a drive and manually idle the engine for a minute or two before shutting it off. I appreciate mechanical sympathy, and so, obviously, do you, Steven.

• How can I replace a damaged compliance plate?

  Given that it’s just a small piece of stamped aluminium, a car’s compliance plate is a big deal as it confirms that the vehicle to which it’s attached meets all relevant rules and regulations to be used on the street. The laws vary from State to State, but in WA right now, it seems that replacing a damaged compliance plate with a new one is not permitted. Instead, what you may have to do is to apply for an exemption to have a compliance plate fitted to that particular vehicle.

  According to the WA authorities (who I contacted about this) “If a vehicle’s original compliance plate is destroyed or lost, it cannot be replaced, however the vehicle owner can apply…for an exemption from having to fit a compliance plate”. There’s a process to be followed including having the car inspected and, if the vehicle is deemed to qualify for the exemption, a note will be made on its registration record to reflect the fact that it doesn’t require a physical compliance plate. This inspection will confirm that the vehicle is legal and hasn’t been stolen or written-off.

  My concern is that it’s something you’re going to have to explain to a buyer when you sell the car on. Even though a car with this exemption is perfectly legal and shouldn’t present any insurance hassles, some buyers might be leery of a car without a compliance plate. For that reason, I’d be doing everything I could to preserve the original compliance plate. Unless there was a fire that melted it, even a bent and buckled compliance plate may be able to be straightened and left attached to the car. That would certainly be my preference.
