3. Safety Information
Always prioritize safety during installation and operation. Improper installation can lead to oil leaks, engine damage, or personal injury. If you are unsure about any step, consult a qualified mechanic.
- Ensure the engine is cool before beginning installation.
- Disconnect the vehicle's battery to prevent accidental starting.
- Wear appropriate personal protective equipment (PPE), including gloves and eye protection.
- Ensure all connections are tight and secure to prevent leaks.
- Check for oil leaks after installation and before driving.
- Do not modify the components of this kit.
4. Setup and Installation
This section outlines the general steps for installing the maXpeedingrods 19-Row AN10 Universal Oil Cooler Kit. Specific vehicle applications may vary. A thermostat is not included with this kit.
- Prepare the Vehicle: Park the vehicle on a level surface and engage the parking brake. Allow the engine to cool completely. Disconnect the negative terminal of the battery.
- Drain Engine Oil: Drain the engine oil into a suitable container.
- Remove Oil Filter: Carefully remove the existing oil filter.
- Install Sandwich Plate Adapter:
- Thread the appropriate threaded adapter (M20 x 1.5 or 3/4 x 16 UNF) into the engine block where the oil filter was located.
- Place an O-ring onto the AN10 oil filter sandwich adapter.
- Mount the sandwich adapter onto the threaded adapter, ensuring it is flush and securely tightened. The oil filter screw diameter is 75 mm.
- Install a new oil filter onto the sandwich adapter.
- Mount Oil Cooler:
- Select a suitable location for the oil cooler, ensuring adequate airflow and clearance from moving parts or hot components.
- Securely mount the oil cooler using the provided bracket or a custom mounting solution. The cooler dimensions are approximately 33 cm x 14.5 cm x 5 cm.
- Connect Hoses:
- Attach the flexible steel braided hoses to the AN-10 fittings on the sandwich plate adapter and the oil cooler.
- Ensure all AN-10 connections are tightened properly to prevent leaks. Do not overtighten.
- Route the hoses away from hot exhaust components, sharp edges, and moving parts. Use hose clamps or ties if necessary to secure them.
- Refill Engine Oil: Refill the engine with the recommended amount and type of engine oil.
- Initial Start-up and Leak Check:
- Reconnect the battery.
- Start the engine and let it idle. Immediately check for any oil leaks around the oil cooler, hoses, and sandwich plate adapter.
- If leaks are detected, shut off the engine and rectify the connections.
- Allow the engine to reach operating temperature and re-check for leaks.
- Check Oil Level: After the engine has cooled, re-check the engine oil level and top up if necessary.

5. Operating Instructions
Once installed, the oil cooler operates automatically to reduce engine oil temperature. No specific user interaction is required during normal operation.
- The oil cooler is designed to maintain optimal engine oil temperatures, especially under high-stress conditions like track driving or heavy towing.
- Regularly monitor your engine oil temperature gauge (if equipped) to ensure proper cooling performance.
- The kit is designed to reduce engine oil temperature by up to approximately 30 °C.
6. Maintenance
Proper maintenance ensures the longevity and effectiveness of your oil cooler kit.
- Regular Inspection: Periodically inspect all hoses, fittings, and the oil cooler for signs of wear, damage, or leaks. Check for any loose connections.
- Cleaning: Keep the oil cooler fins clean from debris, dirt, and insects to ensure maximum cooling efficiency. Use compressed air or a soft brush to gently clean the fins.
- Hose Condition: Check the flexible steel braided hoses for any fraying, kinks, or hardening. Replace them if any damage is observed.
- Oil Changes: Follow your vehicle manufacturer's recommended oil change intervals. The oil cooler does not alter these requirements.
7. Troubleshooting
This section addresses common issues you might encounter with your oil cooler kit.
| Problem | Possible Cause | Solution |
|---|---|---|
| Oil Leakage | Loose AN-10 fittings, damaged O-rings, improperly seated sandwich plate or oil filter. | Tighten all AN-10 fittings. Inspect and replace O-rings if damaged. Ensure sandwich plate and oil filter are correctly installed and tightened. |
| Insufficient Cooling | Blocked oil cooler fins, improper mounting location (lack of airflow), air in the system. | Clean oil cooler fins. Relocate cooler to an area with better airflow if possible. Ensure proper bleeding of the oil system after installation. |
| Hose Damage/Wear | Friction against other components, excessive heat exposure, improper routing. | Inspect hose routing and secure away from abrasive surfaces or heat sources. Replace damaged hoses immediately. |
