The timing belt is one of the most critical components in any diesel engine. If it fails while the engine is running, the damage is almost always severe — bent valves, damaged pistons, and a repair bill that can run into tens of thousands of rupees. For owners of the Tata Harrier, MG Hector, or Jeep Compass with a 2.0-litre diesel engine, the Gates PowerGrip K015684XS is a purpose-built timing belt kit designed for this engine family. Understanding what is inside this kit, and why it matters for your vehicle, is the right starting point before you book the service.
Quick Answer
The Gates PowerGrip K015684XS is a complete timing belt kit designed for vehicles fitted with the Fiat-derived 2.0-litre diesel engine, including the Tata Harrier, MG Hector, and Jeep Compass. The kit includes the timing belt, tensioner pulley, and idler pulley — the complete set of components that should be replaced together during a timing belt service. Always verify the exact engine variant and production year with a Gates catalogue or trusted parts supplier before purchasing.
What Is the Gates PowerGrip K015684XS?
Gates is one of the most recognised names in belt drive technology, with a manufacturing history that goes back over a century. The PowerGrip K015684XS is part of Gates’ automotive aftermarket range for diesel engines. The “K” prefix in Gates’ naming convention identifies this as a kit — meaning it is not just a timing belt, but a collection of components designed to be replaced together.
The kit typically includes:
- Timing belt – the primary component that synchronises the crankshaft and camshaft
- Tensioner pulley – keeps the belt under the correct tension
- Idler pulley – guides the belt path and reduces vibration
Some variants may also include the water pump, depending on the specific kit configuration. Confirm with your supplier whether the K015684XS version you are purchasing includes or excludes the water pump, as this affects both your parts list and labour planning.
Which Vehicles Use This Kit?
The Gates K015684XS is designed for vehicles fitted with the 2.0-litre diesel engine derived from the Fiat Multijet platform. In the Indian market, this engine has been used in:
- Tata Harrier (Kryotec 2.0L diesel)
- MG Hector (2.0L FCA diesel)
- Jeep Compass (2.0L Multijet II diesel)
Important fitment caution: All three of these vehicles have undergone engine and emission specification updates across model years, particularly with the transition from BS4 to BS6 norms. Component specifications may differ between generations. Always confirm the correct kit for your specific vehicle model year and engine code before purchasing.
Why Replace the Full Kit, Not Just the Belt?
This is one of the most common and costly mistakes in timing belt servicing.
The tensioner pulley and idler pulley have bearings that wear at the same rate as the timing belt. If you replace only the belt and reuse old pulleys, a worn bearing can seize during the next service interval — which will snap the new belt and cause the same catastrophic engine damage you were trying to avoid.
A complete kit like the K015684XS solves this by giving you everything that needs to go together, from a single manufacturer, with matched specifications. This is not just a convenience — it is the correct way to do a timing belt service on any modern diesel engine.
Replacement Interval
Timing belt replacement intervals vary by engine design, usage pattern, and manufacturer specification. For the Fiat-derived 2.0-litre diesel engines used in the Harrier, Hector, and Compass, replacement is commonly recommended in the range of 80,000 to 1,00,000 km or approximately every 5 years, whichever comes first.
However, always refer to your vehicle’s owner manual or the manufacturer’s official service schedule. Indian operating conditions — heavy stop-and-go traffic, dusty environments, and extended idling — can place additional stress on engine components and may warrant earlier inspection.
Fitment Checklist
Before placing an order for the Gates K015684XS:
- Confirm your vehicle model: Harrier, Hector, or Compass
- Confirm model year and generation
- Confirm fuel type: diesel only
- Confirm engine code with your dealer or service manual
- Check whether your specific variant is BS4 or BS6
- Verify the kit part number against the Gates official catalogue
- Purchase from a trusted and authorised Gates distributor to avoid counterfeit parts
The timing system is not a component where you want a fitment error or a fake part.
Common Mistakes to Avoid
- Replacing only the timing belt and reusing old pulleys
- Buying based on the car name alone without checking the engine variant
- Purchasing from unverified sellers where counterfeit Gates kits circulate
- Delaying the replacement past the manufacturer’s recommended interval
- Not replacing the water pump at the same time when the engine design makes concurrent replacement practical

FAQ Section
What vehicles is the Gates K015684XS timing belt kit compatible with?
The Gates K015684XS is designed for the 2.0-litre diesel engine used in the Tata Harrier, MG Hector, and Jeep Compass. Always confirm compatibility with your specific model year and engine variant using the Gates catalogue.
Does the Gates K015684XS include a water pump?
The K015684XS kit typically includes the timing belt, tensioner pulley, and idler pulley. Whether a water pump is included depends on the specific kit variant. Confirm with your supplier before purchasing so you can plan the complete service correctly.
How often should the timing belt be replaced on a 2.0-litre diesel engine?
A common recommendation for the Fiat-derived 2.0-litre diesel engines used in the Harrier, Hector, and Compass is every 80,000 to 1,00,000 km or approximately every 5 years. Refer to your owner’s manual for the correct interval for your vehicle.
Can I replace only the timing belt without changing the pulleys?
This is not recommended. The tensioner and idler pulleys wear alongside the belt. Replacing only the belt and reusing old pulleys risks pulley bearing failure, which can snap the new belt and cause serious engine damage.
Is Gates a reliable brand for timing belt kits?
Yes, Gates is a globally respected manufacturer of belt drive components used as original equipment by several vehicle manufacturers. For Indian car owners, purchasing from an authorised distributor is important to avoid counterfeit products.
What happens if the timing belt breaks while driving?
If the timing belt snaps on an interference engine — as most modern diesel engines are — the pistons and valves can collide, causing severe internal engine damage. Timely replacement is essential for engine protection.
How can I verify the correct Gates kit for my vehicle?
Use the Gates online catalogue or consult a trusted spare parts supplier with your vehicle model, model year, engine code, and fuel type. Do not confirm compatibility based on the car name alone.
