Timing Belt Kit and the 2013 Subaru Tribeca: What You Need to Know

The 2013 Subaru Tribeca does not use a timing belt kit as part of its engine design. Instead of a timing belt, this model comes equipped with a timing chain, which performs the crucial job of synchronising the engine's camshaft and crankshaft. This means the traditional timing belt kit, which usually includes the belt itself, tensioners, pulleys, and sometimes a water pump, is not relevant or necessary for this vehicle.

So why is a timing belt kit not used on the 2013 Subaru Tribeca? The main reason comes down to the choice of timing mechanism. The Tribeca's engine, specifically the 3.6-litre flat-six boxer engine, uses a timing chain rather than a belt. Timing chains are made of metal and tend to be far more durable and longer-lasting compared to rubber timing belts. They are generally designed to last the entire life of the engine with little to no scheduled replacement interval. This choice reduces maintenance requirements and improves overall engine reliability.

Timing belts are made to be replaced regularly because they are constructed from reinforced rubber and other materials that wear out over time, usually between 60,000 and 160,000 km depending on the manufacturer's recommendations. They need the timing belt kit replacement to prevent possible belt failure, which can cause severe engine damage. On the other hand, timing chains, like the one in the Tribeca, do not need this kind of scheduled replacement, though they might require inspection and occasional tensioner or guide replacements if any issues arise.

Even though a timing belt kit isn't used on the 2013 Subaru Tribeca, it's still key to keep an eye on the timing chain's condition during regular servicing. A failing timing chain or a worn tensioner can cause rattling noises, engine misfires, or worse, so mechanics will take steps to ensure everything is running smoothly.

For vehicles where a timing belt kit is relevant, like some other Subaru models or various other makes, the timing belt kit serves a very important role. It is a maintenance package that ensures the engine timing stays in perfect sync, avoiding costly repairs from belt failure. The kit usually includes:

• The timing belt itself, made from rubber composite and reinforced with fibres
• Tensioners which keep the belt tight and correctly aligned
• Pulleys that guide and support the belt during its rotation
• Sometimes the water pump, since it's often driven by the timing belt and may as well be replaced while the belt is off

The timing belt's job is to keep the crankshaft and camshaft rotating together in perfect harmony. This coordination opens and closes the valves at precise moments with respect to the position of the pistons. If the belt snaps or slips, the engine timing goes haywire, which can cause the valves to crash into the pistons in interference engines, resulting in expensive engine damage.

So if your Subaru did have a timing belt, replacing the timing belt kit according to the manufacturer's recommended intervals is crucial. Typically, this replacement happens every 90,000 to 150,000 km, depending on the specific vehicle and engine. Doing this replacement includes swapping out the timing belt plus all associated components to ensure reliability and longevity. Mechanics often recommend changing the water pump at the same time, even if it isn't strictly necessary, because the majority of the labour is already done.

People often underestimate how vital this job is. A fresh timing belt kit means peace of mind that your engine's timing will remain spot on, avoiding potential breakdowns and costly repairs down the track. Plus, new tensioners and pulleys reduce the risk of unexpected wear or noises.

Although the 2013 Subaru Tribeca sports a timing chain instead, owners still need to keep an eye on engine service intervals and listen out for any unusual noises like rattles or clunks from the front of the engine. Chains can stretch or tensioners can fail, especially once the vehicle has clocked significant mileage or if maintenance has been neglected. Most mechanics will inspect the timing chain during major services or if you notice any performance issues.

In the end, the key takeaway for a 2013 Subaru Tribeca owner is that there is no timing belt kit to worry about, which cuts down on one important maintenance task. But regular servicing still matters to keep the timing chain and all other engine components healthy. Attention to these services will keep the Tribeca running smoothly for many years and kilometres without the need for a timing belt replacement.
