Automation of the timely injection of fuel into the car engine and the removal of exhaust gases from it largely depends on the smooth operation of the roller and timing belt. The belt is made using high-strength materials: rubber with special additives, reinforcing threads. Quite often, multifunctionality and versatility, as well as a constant friction force on the pulleys, contribute to increased wear of this spare part. Therefore, it is extremely important to follow the manufacturer's standard recommendations and change it in time to avoid a break. The high quality of the raw materials provides the finished product with elasticity, flexibility, and makes it possible to use it both in winter and in summer. Kimiko rollers and belts are made for Chinese car brands and can be installed instead of original components with a good warranty on the operation of the part.
