Two types of timing systems are used in modern engines: the timing belt and the timing chain. Both components are essential for keeping your engine running smoothly, but which one is better?
Goto SBT to know more.
Timing belts and timing chains both serve the same purpose - to keep the crankshaft of an engine synchronized with its camshafts. Both are integral components for any internal combustion engine, but there is a key difference between them: timing belts use rubber links that are connected in a loop, whereas timing chains are metal linkages connected by chain links.
It varies based on your engine type. Here are the pros and cons of each:
Pros: Timing belts are quieter and tend to last longer than timing chains. They also take up less space in the engine, making them ideal for cars with tight engine compartments. Additionally, they are relatively inexpensive and easy to replace.
Cons: Belts are made of rubber, so they can become brittle over time and may need to be replaced more often than timing chains. Belts also tend to stretch more easily than chains, which can cause your engine to run inefficiently or even break down completely if the belt slips off its sprocket.
Pros: Timing chains are sturdier than belts, making them better suited for higher-performance engines. They also last longer and require less maintenance overall.
Cons:
Timing chains can be expensive to replace because they need to be removed from the engine before being replaced. Additionally, timing chains tend to generate more noise than timing belts, so if you're looking for a quiet ride, this may not be the best option.
When it comes to cost, timing belts generally tend to be cheaper than timing chains. However, timing chains typically last longer and do not require as much frequent maintenance as timing belts, which makes them the better option in terms of value.
Timing chains require more frequent maintenance than timing belts, as they need to be checked and adjusted regularly to ensure proper functioning. It is recommended to check timing belts regularly for any signs of damage and replace them after covering a distance of 50,000 to 90,000 miles.

When it comes to durability, timing chains are generally more reliable and longer lasting than timing belts. Timing chains have a longer lifespan than timing belts, with a potential mileage of up to 150,000 miles before replacement. In contrast, timing belts usually need replacement between 50,000 and 90,000 miles.
When choosing between a belt or chain for your engine, you should consider various factors. These include cost, weight, level, durability and maintenance requirements. Depending on the type of vehicle you have, one option may be more suitable than the other.
Ultimately, the decision between a timing belt and a timing chain comes down to preference. Timing belts offer lighter weight and quieter operation while chains are stronger and last longer. Cost wise, belts tend to be cheaper but in terms of value for money, chains may be better due to their longevity. Maintenance requirements should also be taken into consideration when making your choice as it affects both performance and cost over time. It is important to research which option is best for your specific vehicle before making a decision.
Developments in engines bring about new innovations in the timing system, but also new problems and different methods of maintenance. In this blog we will discuss the different types of timing chains and belts, defects and how to maintain these parts.
The timing and drive of the engine can nowadays be controlled by the timing chain, timing belt or wet-driven timing belt. These types of parts all have their own advantages and disadvantages:
After the emergence of smaller engines, the timing chain has become more popular again. Despite the fact that the system works almost without problems with the right maintenance, annoying problems such as the stretching of the chain do occur. If the chain is very stretched, there is a chance that the camshafts will no longer have the correct timing. The fault light will come on, but the chance of the pistons hitting the valves is also increasing. The chain may even break or skip, causing major consequential damage.Problems with the timing chain can have various causes. The quality of the oil and the degree of oil contamination, such as oil diluted with fuel or condensation caused by an engine that cannot raise its temperature due to frequent short trips, play a major role. In addition, wear of other components including chain tensioners and guides is a possible cause.
The timing belt can also cause different problems, such as various forms of damage, deterioration or a broken belt. These consequences are often blamed on the use of the wrong oil, but there are several causes that can cause problems. For example, we recently read in an AMT article how the presence of fuel in the oil can be the cause of a defective timing belt. In addition to contaminated or incorrect oil, the quality of the product, damage from other components or incorrect belt tension can of course cause damage to the component or even greater engine damage.
The most important precaution to prevent these problems is of course maintenance. Oil should be checked and changed regularly. It is therefore advisable to change the oil on time according to the change interval. In addition, when replacing the timing chain or belt, it is always recommended to replace it as a set (according to the prescribed replacement interval), because in addition to the belt or chain, other components also have a number of kilometres to run, such as guides, idlers, tensioner pulleys and water pumps. For advice on these replacement parts, you can always contact our product specialists so that they can give you appropriate and personal advice on your task and problem.
In addition we have a wide range of products from brands such as INA, Swag, Dayco, BGA and Hepu to repair a timing system with OE quality parts. Our specialists can also put together complete sets of parts for you, so any matching products such as valves and water pumps are also added to your order.
