Installation Notes and Tips

Confirm the hose path matches the upper filler-neck-to-engine routing before installation. Inspect the mating necks and clamps for corrosion, residue, or edge damage, and replace any worn clamps as needed. Verify the end diameters and centerline length against the removed hose to ensure proper seating and routing on the Nissan Altima or Nissan Maxima cooling system.
