5. Installation
This fitting is designed for simplified installation without the need for welding. Always ensure the engine is cool and depressurized before beginning any work on the oil system.
Installation Steps:
- Prepare the Oil Pan: Ensure the M18x1.5mm port on your oil pan or sump is clean, free of debris, and has intact threads.
- Assemble the Fitting: Place one metal with rubber washer onto the threaded portion of the 10AN plug adapter.
- Insert Adapter: Carefully thread the 10AN plug adapter into the M18x1.5mm port on the oil pan. Hand-tighten first to avoid cross-threading.
- Secure with Nut: Place the second metal with rubber washer onto the adapter from the outside of the oil pan, followed by the M18x1.5mm adapter nut.
- Tighten Components: Using appropriate wrenches, tighten the adapter and nut securely. Ensure the washers are properly seated to create a leak-proof seal. Do not overtighten, as this can damage threads or washers.
- Connect Oil Line: Attach your 10AN oil return line to the adapter. Ensure this connection is also secure and leak-free.
- Final Check: After installation, start the engine and carefully inspect all connections for any signs of oil leaks. Address any leaks immediately.
Note: Professional installation is recommended if you are unfamiliar with automotive oil system modifications.
