Commonly, when a timing belt fails, all the other parts around it also require replacement. Because of this reason, it is better to change not only the belt but also other engine parts such as the water pump and tensioner. It means a better and long-lasting repair, prevention of engine risks and savings for the pocket.

Buying a timing belt kit has been proved to reduce 50% of interventions and an estimated 5 hours of labor. That is, one box solution that contains all of the components required for an optimal timing belt replacement.

What criteria should you follow when choosing a distribution kit?

Ensuring that your vehicle has a strong and reliable engine is essential for safe and efficient driving. To achieve this, there are several key factors to consider when maintaining your vehicle's engine. By taking care to address these critical aspects, you can help to extend the life of your engine and achieve optimal performance.

Compatibility and fit

Timing belt kit components must be compatible with your car engine. Timing belts can differ in strength, thickness and temperature resistance in relation to suiting specific vehicle needs. If you choose without checking compatibility, premature failure will potentially arise.

In order to do so, it is key to conduct research before selecting and ordering; by checking the part number and every specification that will ensure a proper fit in the engine. Accurate instructions also play an important role in securing an easy and safe installation of all parts involved.

Quality and guarantee

Do not jeopardize quality for price matters, as this will negatively affect durability; raising the costs associated with fixings and reparations in the long term. A reliable performance is a must so, the investment will surely be worth it.

Best timing belt kits are those whose quality is at least equivalent to OE standard specifications regarding fit, functionality and performance indicators. Timing belt components must be tested under the same conditions as per OE specifications, with proven materials guaranteeing superior resistance against heat, pressure and external wear.

Existing reviews and additional support materials such as technical specifications, videos and unboxings can help you identify specifically how the item(s) should turn out. Only an experienced manufacturer can offer a backed-up product.

Parts included on the timing belt kits

When it comes to maintaining the engine of your vehicle, few components are equally critical as the timing belt. To help ensure that your timing belt is functioning properly, it's important to understand the various parts that are included in our timing belt kits:

Timing belt

It is in charge of keeping internal combustion engines running and the vehicle's pistons and valves operating correctly. Premium quality belts must prove resistant to changes in temperature, water and oil to ensure optimized durability.

Water pump

The water pump is directly adjacent to the timing belt and is intended to keep the optimum temperature of the engine at all times, so it must remain properly sealed to avoid leakage. In most cases, the timing belt drives the water pump, which is why it is the right time to replace the water pump when replacing the timing belt.

Tensioners

A belt tensioner or idler pulley is the system that guides the timing belt on a car engine, keeping it tight and running smoothly. Its main function is to stop the belt from slipping, avoiding drivability issues derived from a loose timing belt.

Bearings and screws

Bearings and screws are what holds together and in place the different components of engine timing belt kits. Dolz bearings are equivalents to OE and resistant to temperature changes and motor vibrations. They are manufactured with high quality raw materials to reduce friction and wear.

Choose Dolz's timing belt kits for superior engine performance

Timing Belts and Timing Chains ..Know before you buy

In my short time here on the CRVL forums, I've seen no mention of timing belts or timing chains and thought that I'd put a little bit of info out there for others to consider. In my search for vehicles (currently looking at mini-vans) ..I always make a point to to steer clear of vehicles that use timing belts as opposed to timing chains because timing chains generally never need to be replaced whereas timing belts need to be changed out every 60 to 80k miles (and the job is never cheap) ..In my years of finding vehicles for myself or others, I've noticed that a lot of people tend to trade in or put their timing-belted vehicles up for sale right about the same time that a belt replacement is due. Dealers don't usually replace timing belts prior to resale and they're in no hurry to let this be known so if you're looking for a vehicle it's always good to ask if the belt has been replaced and how long ago the service was completed. Having said that much, I'll leave it up to you to google 'timing belt vs. timing chain'  to further broaden your knowledge on what I consider to be one of the more important things to consider when making a purchase. For the record, I've settled on seeking out a Kia Sedona due to the fact that Kia used timing chains for every year of production. It's really easy to find out if your vehicle has a chain or belt by simply searching the name of your vehicle along with 'timing belt or timing chain?'. Anyway, I just thought I'd throw that out there. Good luck!

PlethoraOfGuns said: Timing belts are no bueno. If you have timing belts, change them when you have to! They will break and destroy your engine!!! Timing chains are much better. Chains do stretch, and the tensioners could fail. Chains rarely need replacement, but annual checkups don't hurt. I had a Jeep with the famous 4.0L engine and the timing chain guide broke off and very bad things happened inside the head. Now I only buy vehicles with timing gears. They are good way past the life of the vehicle...


This only applies to Interference engines.

If you have a non interference engine, it makes no difference if the belt breaks.  You won't damage anything.

It's one of the reasons  I :heart: older cars.

Also, I have never paid to have a timing belt replaced.   They are not that hard to do so and I've gone well over 100K miles with no problem.
Buy the best timing belt you can get and stop worrying.
