What It Helps Address

  • Maintenance replacement when the original pump shows wear

Installation Notes and Tips

Verify engine application by year, make, and model before installation. Clean the mounting surface thoroughly and replace worn sealing surfaces as needed so the included installation sealing devices can seat correctly. After installation, refill and bleed the cooling system according to Subaru service procedures and check for leaks at operating temperature.
