Storage & logistics

Proper storage of remanufactured injectors for the 1.7 CDTI 131 hp is essential to maintain their condition and performance. These components should be kept in a clean, dry environment, away from direct sunlight and temperature extremes, to prevent degradation of seals and internal components. For bulk buyers, organizing injectors by engine model and application ensures efficient retrieval and reduces the risk of misplacement. Regular inventory checks help identify any units that may have been compromised by improper handling or storage conditions. When transporting injectors, use padded containers to avoid physical damage, and ensure they are secured to prevent movement. For garages, implementing a first-in, first-out (FIFO) system helps maintain the freshness of stock, reducing the likelihood of using outdated or degraded parts. Suppliers should also provide clear handling instructions to prevent contamination from dust or moisture, which can affect injector performance.
