It’s important to understand, but is the engine in your Mazda 2 timing belt or chain driven? That’s because a timing chain should last the life of the car with no extra maintenance, while a timing belt will need to be replaced at regular intervals. If you ignore timing belt changes, the belt can snap in service and destroy the whole engine.

Fortunately, the engine in the Mazda 2 uses a timing chain, so should require no special maintenance for as long as the rest of the car is running properly. That gets around the problems of the cam drive belt replacement as well as the associated cost.

This advice applies to both engines used in the Mazda 2 since 2002 and covers the ZY-VE engine (2002 to 2014) and the later V-P5 and F-P5 engines. It’s also dependent on regular oil changes and other maintenance having been carried out.

The recommended Audi Q5 engine oil is a fully synthetic oil with a viscosity rating of 5W30. Regardless of what engine is fitted to your Audi Q5 oil type and grade remains the same from 2017 onwards, regardless of whether the car in question is fitted with the two-litre turbo-petrol, two-litre turbo-diesel or the three-litre V6 engine.

In older, simpler cars than the Q5, an oil change is as simple as opening the drain plug to remove the old oil, spinning on a replacement oil filter, replacing the plug and refilling the engine with oil.

But the complex specifications of the modern Audi line-up mean that there’s often a bit more to this critical maintenance job. For instance, some of the fasteners Audi uses in the engine bay might require specialised tools. There are also sometimes complicated engine covers above and below the engine that need to be removed for a service to take place. Even turning off the service reminder light after the oil change can be confusing if you don’t have the knowledge or the gear to do it. Suddenly, a DIY job has just become a much bigger size task and “how to change oil on a Audi Q5” has become a very complex question.

For many Q5 owners, then, an oil change is a good job for an accredited service centre with a trained mechanic who can also advise on how often to change oil and the correct service interval for other important jobs.

Ford’s popular PX Ranger (sold from 2011 to its replacement in 2022) marked a distinct move away from timing belt technology to drive the engine's inlet and exhaust cam. So, regardless of what engine your PX Ranger has fitted to it, the Ford Ranger timing belt or chain question is answered with a simple response: It’s a timing chain.

That means the timing chain should be good for the life of the vehicle and will not require replacement at regular intervals, unlike engines with a rubber drive belt belt, provided oil changes and other maintenance has been carried out properly. This gets around the rubber drive belt problems of periodical replacement and the associated cost.

This advice covers every PX Ranger engine, including the 3.2-litre five-cylinder diesel, the 2.2-litre four-cylinder diesel, the two-litre twin-turbo diesel and even the short-lived (2011 to 2015) 2.5-litre petrol engine.

The Fiat 500 Bluetooth system incorporated a Windows-based technology called Blue & Me. The idea was to give full hands-free control of the phone’s functions, but how to connect Bluetooth to Fiat 500 hardware is similar to any other system.

Bluetooth Fiat 500 pairing starts with enabling Bluetooth on your phone and switching the setting to Discoverable. From there, you use the car’s info-screen menus to find Settings, then select User Pairing. Then tap the Blue & Me prompt on the screen and type the PIN into your phone.

That should ensure the connection and reinstate it whenever the car detects that phone.

The catch is that Fiat 500 Bluetooth wasn’t available on every model. Early (2008 and 2009) base model (Pop) Fiat 500s sold in Australia didn’t have Bluetooth connectivity. If you bought the Sport or Lounge model, you got this feature, but only Pops built in 2010 or later had Bluetooth.

Toyota Camrys from 2017 onwards use the same engine oil, regardless of the engine or drivetrain fitted. So, the recommended Toyota Camry engine oil for either the 2.5-litre petrol engine, the 3.5-litre V6 and even the Hybrid Camry, is a fully synthetic engine oil with a rating of 0W20. This Toyota Camry oil type is quite `light’ (thin) but ensures the engine is lubricated quickly, especially in the case of the Hybrid version where the engine is stopping and starting regularly.

When it comes to how to change oil on a Toyota Camry, the task is really no more complex than it is for other conventionally laid out cars. Which is to say that if you have the right tools and some experience, this critical piece of maintenance shouldn’t pose too many DIY obstacles.

To carry out this service, though, you’ll need to know the size of the drain plug, what replacement oil filter to buy as well as the drain tubs necessary to catch the old oil. You can find out the correct oil change interval (how often to change oil) in the specifications section of the car’s owner’s manual.

If that all sounds a bit too hard, a service centre with a qualified mechanic should be able to handle the job relatively cheaply and will attend to the details like disposing of the old oil correctly and safely and resetting the service-reminder light on the dashboard.

Ford Focus Bluetooth wasn’t a reality until the new model that arrived in 2011. But at the point, it was standard on every trim level (including voice command) and was many people’s first taste of the tech. Prompting a lot of online questions along the lines of how to connect Bluetooth to Ford Focus?’ It’s actually pretty easy. That said, the best of these earlier systems used Ford’s SYNC tech which was introduced on Focuses built from August 2012 onwards.

Bluetooth Ford Focus pairing starts with switching on the Bluetooth on your phone and making the device discoverable. Then press the Phone button on the car’s menu system and follow the prompt to Add A Device. You should then be able to select SYNC from your phone’s list of available devices, enter the security code displayed on the car’s screen and your Ford Focus Bluetooth pairing is done.

From there, you can make and receive calls, view text messages and stream music, all via the voice command system.

Subaru’s engines over the decades have used both popular methods of driving the engine’s camshafts, but what about the mid-sized cross-over Subaru? Is the Subaru XV timing belt or chain?

Actually, all XVs from the arrival of the model in Australia in 2012 to now, have all used the same FB20 engine. Which means every Subaru XV sold here has used a timing chain rather than a timing belt.

For most owners, this is good news as the timing chain should be maintenance-free for the life of the car, while a timing belt needs periodic replacement.

The recommended Honda Civic engine oil is a fully synthetic 0W20 oil. That’s what oil manufacturers say is best for any of the Civic engines sold here from 2017 onwards. That includes the 1.8-litre and 1.5-litre petrol engines as well as the high-performance Civic Type R model.

Like many Honda engines over the years, the Honda Civic oil passages can be quite small and narrow, so a good supply of clean, fresh oil is critical to these cars. That’s also why the Honda Civic oil type is a very light (thin) oil; so it flows easily and quickly.

If you know how to perform a service on any other modern car, then you already know how to change oil on a Honda Civic. It’s a DIY maintenance job for anybody who is an average mechanic and involves little in the way of tools apart from an oil filter wrench and the correct size socket or spanner to tackle the drain plug. You’ll also need drain pans and the car’s owner’s manual which will tell you things like how often to change oil, any other service interval info and specifications for how tight the drain plug needs to be tightened.

Failing all that, a trip to any service centre will be able to supply the oil and replacement filter, dispose of the waste oil and even reset the service reminder light as part of the process.

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.

It sounds like a pretty nitty-gritty tech question, but is the camshaft in the engine of the Kia Rio timing belt or chain driven? There’s a good reason for knowing the answer, though, as it determines whether you need to add a crucial routine maintenance step to your ownership.

In cars with a toothed rubber timing belt, the belt and its tensioners need to be changed at an interval recommended by the car’s manufacturer to avoid expensive belt failures which can ruin the whole engine. Ignore this maintenance at your peril.

The good news is the GL4C engine as used in the Kia Rio since 2016 uses a timing chain which should be good for the life of the engine and not need any extra maintenance.
