- Check the packaging for protective measures, such as sealed containers and shock-absorbent materials, to prevent damage during transit.
- Prioritize turbos with a consistent remanufacturing process, as this ensures uniform quality across batches and reduces the risk of premature failure.
- Opt for units with clear labeling and documentation, including core deposit instructions, to streamline the return of your old turbo and simplify accounting.
- Select a supplier with a transparent rotation policy, as this delivers access to fresh stock and minimizes the chance of receiving outdated or improperly stored components.
- Choose a turbo that aligns with your repair timeline, as some units may require additional preparation or testing before installation.
Storage & logistics
Proper storage of exchange standard turbos is critical to maintaining their performance and longevity. Keep units in a climate-controlled environment, away from moisture and direct sunlight, to prevent corrosion or degradation of seals. For bulk orders, use sturdy shelving and organize by reference to facilitate quick retrieval. Always handle turbos with care, avoiding impacts or drops that could damage the housing or internal components. If storing for extended periods, inspect units periodically for signs of wear or contamination, and ensure they remain in their original packaging until ready for use.
