What is a car timing belt?
Timing belts in vehicles are the alternative to timing chains. Both components make up the main part of a timing system, in charge of making a vehicle run. The timing belt synchronizes the movement of the crankshaft and the camshafts to ensure that the engine’s valves open and close along with the pistons.
The timing belt must turn the camshaft and crankshaft in unison and at the right speed points. As the crankshaft turns, it sets the timing belt in motion across the four-stroke combustion cycle:
Characteristics of a timing belt
The timing belt is a rubber belt with hard teeth that interlock with the cogwheels of the crankshaft and the camshafts. In many modern engines, timing belts have replaced metal timing chains as a quieter and lighter alternative, while remaining fairly durable.
Even though timing belts are durable and highly efficient, they are constantly under stress and subject to great forces inside the vehicle’s engine. Operating in high heat environments makes them impossible to last forever, so vehicles will require a timing belt replacement at some point during its life.
Timing belt kit components
Timing belt kits were born as a more reliable, convenient and accessible way to carry out timing belt replacements and repairs. For this reason, the pump market has evolved towards complete one box solutions that include the timing belt together with the rollers, bearings and screws required to correctly change the vehicle’s distribution, as well as an optional water pump.
The reason why most quality timing belt kits include a water pump in its components, is because it is highly recommendable to replace both components at the same time. In most cases, doing so will save costs and labour, as well as ensuring a predictive and safe form of maintenance.

When should you carry out a car timing belt replacement?
All the components of the distribution kit, including the water pump, are key elements for the proper cooling and operating of any vehicle’s engine and cooling system.
Timing belts are therefore a maintenance item; they can wear out and fail without warning, and should be replaced on a regular basis. Typically, timing belts should be changed every 4-5 years second usage.
However, the first principle for optimum maintenance is reading your owner’s manual, as every manufacturer differs. It pays to know which kind of engine you have and what are its recommended replacement intervals.
Timing belt replacement recommendations
Regular checks are the most effective way to save you money and avoid problems in the long run. The frequency of your replacements will depend on many factors, including the age of your current belt, the distance travelled and the model of your car.
Prevention is key to an optimal car maintenance, as there are usually no certain clues to indicate a worn belt that may be close to snapping. If you have a decent maintenance schedule in place, you can avoid the additional wear and tear that will result in problematic warning signs.
Because water pumps and timing belts are so closely related in terms of their functioning, and because access to them usually requires removing both parts, distribution kits including both components are largely preferred by car workshops for maximum efficiency.
