Product Details

This Four Seasons hose assembly is part of the brand’s Hose Assembly line, backed by more than 50 years of mobile A/C experience. Four Seasons engineers and tests its HVAC components for long service life and dependable operation, making this suction line a practical replacement for the factory-style refrigerant path on Honda Passport, Honda Ridgeline, and Honda Pilot models.

Common A/C Line Issues It Can Address

This hose assembly is listed for 2019-2025 Honda Passport, 2020-2025 Honda Ridgeline, and 2019-2022 Honda Pilot, all in suction line applications. Confirm that the vehicle does not require a service port or bracket on the replacement part, since this assembly is supplied without either feature.
