Installation Notes and Tips

Verify the engine uses a threaded oil filler cap before ordering. Match the cap to the existing filler neck or oil filler tube style, especially on E-250 and E-350 Econoline Club Wagon applications noted as without oil filler tube. Clean the sealing surface before installation and tighten the cap securely by hand to ensure proper seating. Confirm fitment against the vehicle’s year, make, model, and engine configuration before installation.
