Installation tips and care

Before installation, verify compatibility with your cooling system’s reference reservoir (603-001 type) and ensure the mounting area is clean and free of debris. Position the bottle where it can vent properly and avoid contact with hot surfaces. Periodically check the cap seal and mounting hardware to maintain a secure, leak-free setup.
