Timing Belt Kit for the 2017 Mazda BT-50: What You Need to Know

When it comes to the 2017 Mazda BT-50, understanding whether it uses a timing belt or not is key for proper maintenance. For this particular model, especially in the popular 3.2-litre five-cylinder turbo-diesel variant, the timing belt kit is actually not relevant. Rather than a timing belt, Mazda equips the BT-50 with a timing chain. This means you won't find a timing belt kit as a service item for this vehicle.

So why is the timing belt kit not used on the 2017 Mazda BT-50? It all comes down to the engine design. The five-cylinder turbo-diesel engine under the bonnet uses a metal timing chain instead of a rubber timing belt. Timing chains are designed for longevity and typically run inside the engine oil, which keeps them lubricated and cool. This makes chains more durable compared to belts, which are made of rubber and need replacing periodically.

Rubber timing belts naturally wear out over time and can fail if not changed at recommended intervals, potentially causing major engine damage. Timing chains, on the other hand, are built to last much longer, often for the full life of the engine. Because of this, they don't require routine replacement like timing belts do. The design choice for a timing chain in the BT-50 is also due to the diesel engine's higher torque, which benefits from the more robust chain setup.

While the timing belt kit isn't something BT-50 owners need to worry about, it does not mean the timing chain is completely maintenance free. It's still important to keep an eye (and ear) on the health of the timing chain over time. Chains can stretch, or their tensioners and guides can wear out. But as a general rule, replacing the timing chain itself is not part of regular maintenance - usually, it only gets addressed if a problem develops.

For servicing the 2017 Mazda BT-50, focus should be on oil changes according to the manufacturer's guidelines. Since the timing chain runs in engine oil, keeping the oil clean and changed at regular intervals is crucial in prolonging the chain's life. Dirty or degraded oil leads to increased friction and wear on the timing chain components.

It's also worth noting that the timing belt kit generally includes a timing belt, tensioner, and idler pulleys, all items aimed at timing belt-equipped engines. Since these components are not fitted on the BT-50's diesel engine, there is no timing belt kit available or required. Parts to pay attention to instead include the chain tensioner, guides, and sprockets, however these typically only need replacement if there is a symptom such as rattling noises from the front of the engine or trouble starting.

For anyone used to petrol engines or older diesels, the absence of a timing belt replacement interval can be a bit surprising. Petrol variants of the Mazda BT-50 with 2.2-litre or 3.0-litre engines also use timing chains rather than belts. This consistent use of chains across the BT-50 line speaks to Mazda's focus on durability and reduced maintenance in this ute.

In terms of servicing tips:

• Stick closely to the scheduled oil changes, using the correct grade and quality of oil as outlined in the owner's manual.
• Keep an ear out for any unusual noises from the engine bay, such as rattles or ticking, which can indicate timing chain or tensioner wear.
• If your BT-50 is showing signs like hard starting or shuddering, have the timing chain components checked by a qualified mechanic.
• Regularly inspect other critical service items like the serpentine belts, coolant system, and fuel filters, but rest assured a timing belt kit replacement is not on the list.

Overall, the 2017 Mazda BT-50 owners can breathe a sigh of relief on one maintenance front. No timing belt kit means you avoid that often costly job of belt replacement at the 100,000 to 150,000 kilometre mark which many other vehicles require. Instead, you get the benefit of a robust timing chain system designed to last the life of the vehicle with the right care.

So, if you are searching for timing belt kits for your 2017 Mazda BT-50, you won't find any. Focus your attention on regular servicing, using quality oils and fluids, and keeping the engine in good shape to enjoy many kilometres on the road with this capable and reliable ute.
