Remove the factory oil filter. Install the Mishimoto oil sandwich plate between the engine block and the new oil filter. Ensure proper orientation and tighten to the manufacturer's specified torque. Apply a thin layer of fresh oil to the gasket of the new oil filter before installation.
- Connect Oil Lines: Connect the braided stainless steel oil lines from the oil sandwich plate to the oil cooler core using the -10AN fittings. Ensure all connections are secure and free from kinks or obstructions.
- Refill Oil and Check for Leaks: Add engine oil to the manufacturer's recommended level. Start the engine and allow it to reach operating temperature. Carefully inspect all connections for any signs of leaks. Shut off the engine and re-check the oil level, adding more if necessary.
- Reassemble Vehicle: Reinstall all removed bumper components and undertrays. Reconnect the battery.
5. Operating Instructions
The Mishimoto Oil Cooler Kit operates automatically to regulate engine oil temperature. Once installed, no manual operation is required. The system is designed to:
- Maintain engine oil within optimal temperature ranges, especially during high-performance driving or in hot climates.
- Reduce the risk of oil degradation and engine wear caused by excessive heat.
- Increase the overall oil capacity by approximately 0.75 quarts, contributing to better thermal stability.
For kits equipped with a thermostatic sandwich plate, the thermostat will regulate oil flow to the cooler, allowing the engine oil to reach operating temperature quickly before engaging the cooler for heat dissipation. Non-thermostatic kits will route oil through the cooler constantly.
6. Maintenance
Regular inspection and maintenance will ensure the longevity and performance of your oil cooler kit.
- Routine Checks: Periodically inspect all oil lines and fittings for signs of wear, leaks, or damage. Ensure all connections remain tight.
- Cooler Fin Cleaning: Over time, debris can accumulate in the oil cooler fins, reducing efficiency. Carefully clean the cooler fins with compressed air or a soft brush to remove any obstructions. Avoid using high-pressure washers directly on the fins.
- Oil Changes: Follow your vehicle manufacturer's recommended oil change intervals. The increased oil capacity of the system should be accounted for when refilling.
- Fluid Levels: Regularly check your engine oil level and top off as needed.
7. Troubleshooting
If you encounter issues with your Mishimoto Oil Cooler Kit, consider the following common troubleshooting steps:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Oil Leaks | Loose fittings, damaged lines, improper sandwich plate installation, faulty gasket. | Inspect all -10AN fittings and sandwich plate connections for tightness. Check oil lines for damage. Ensure sandwich plate gasket is properly seated and not pinched. Replace any damaged components. |
| Engine Oil Overheating | Blocked cooler fins, insufficient oil, air in the system, faulty thermostatic plate (if applicable). | Clean cooler fins. Check oil level and top off. Ensure proper bleeding of air from the system. If thermostatic, verify its function. |
| Unusual Noises | Loose mounting, lines rubbing against other components. | Verify all mounting brackets are secure. Inspect oil lines for contact with moving or hot parts and adjust routing if necessary. |
If troubleshooting steps do not resolve the issue, contact Mishimoto customer support or consult a qualified automotive technician.
