How to choose
Selecting the right turbo for your OM646 156 hp involves more than just matching the reference number. Consider factors like core condition, remanufacturing standards, and supplier reliability to ensure long-term performance and avoid hidden costs.
- Prioritize turbos with a documented remanufacturing process, including core inspection and component replacement, to ensure consistent quality and longevity.
- Check the supplier’s return policy for used cores, as some may require a core deposit to offset recycling costs and encourage responsible disposal.
- Verify the turbo’s compatibility with your specific Mercedes-Benz model and production year to avoid mismatches that could lead to performance issues or damage.
- Opt for turbos from reputable brands like SL Turbo or Garrett, which are known for their adherence to original equipment specifications and rigorous testing protocols.
- Assess the packaging and handling instructions provided with the turbo, as proper storage and transport are critical to maintaining the unit’s integrity before installation.
- For workshops, consider the availability of technical support and warranty terms, which can provide added confidence in the product’s reliability and your investment.
- Evaluate the turbo’s physical condition upon arrival, including the presence of protective covers and seals, to ensure it has not been damaged during shipping or storage.
Storage & logistics
Proper storage of exchange standard turbos is essential to preserve their condition before installation. Keep units in a clean, dry environment, away from direct sunlight and temperature extremes, to prevent corrosion or seal degradation. For bulk purchases, use sturdy shelving and label each box with the turbo’s reference number and model compatibility. If storing for extended periods, periodically inspect the units for signs of moisture or physical damage, and ensure the packaging remains intact to protect against contaminants. Always handle turbos with care, avoiding drops or impacts that could compromise internal components or alignment.
