Four Seasons A/C Refrigerant Discharge Hose P/N:65505
Four Seasons 66591 a/c refrigerant discharge hose for the 2011-2016 Toyota Sienna carries refrigerant away from the A/C compressor as part of the discharge line.
Oily residue at the hose or its fittings, weak cooling or lost refrigerant can point to a leaking discharge hose. These signs alone do not prove the hose is the problem, since a leak at another A/C component can look the same.
This hose is a direct-fit replacement for the 2011-2016 Toyota Sienna.
Gaskets, o-rings or seals to replace the product.
