  Cap – Subaru (45153AA001)

  The Cap – Subaru (45153AA001) is a genuine OEM component crafted by Subaru to meet the exacting standards of the factory coolant reservoir system. Made from durable, heat-resistant plastic and precision-sealed to Subaru’s specifications, this cap maintains proper pressure within the cooling system—helping to prevent coolant loss, boiling, and overheating.

  Designed specifically for compatibility with select Subaru models such as the Forester, Outback, Impreza, and Crosstrek, the 45153AA001 seamlessly aligns with the factory overflow reservoir neck. Its engineered seal and venting groove support the manufacturer’s intended pressure rating—typically around 1.1 bar (16 psi)—ensuring coolant remains contained even under high engine temperatures.

  Professional mechanics and DIY enthusiasts alike will find the 45153AA001 easy to service. Its ergonomic design and factory-standard threading make removal and installation quick and hassle-free. Because it's built to Subaru’s exact dimensions, the cap installs securely without the risk of misalignment, cross-threading, or coolant seepage—all of which can degrade system performance or lead to premature failure.
