Using this Billetworkz coolant overflow cap is easy. Just remove your old cap and replace it with this new one. It's a direct fit for the listed Subaru models. When it comes to maintenance, since it has an anodized or powder - coated finish, it's quite durable. But you should still keep it clean. You can use a mild cleaner and a soft cloth to wipe it down. Avoid using abrasive materials as they could scratch the finish. Also, make sure to check the cap regularly to ensure it's properly sealed. If you notice any signs of leakage or damage, replace it right away. That way, your engine bay will stay stylish and your coolant system will work smoothly.
