Four Seasons 56423 a/c refrigerant suction hose for the 2003-2006 Chevrolet Silverado 1500 and other vehicles is a suction line hose assembly that carries low-pressure refrigerant back toward the A/C compressor.
- Engineered and tested for years of trouble-free operation, backed by over 50 years of mobile A/C experience
- Double wall barrier hose compatible with R1234YF, R134A or R12
- Crimp fitting connection
- Application specific design
Oily residue near the hose fittings, a visibly damaged hose or weak cooling can mean the suction hose is leaking. Those signs alone do not prove the hose is the problem, since a leaking condenser, for one, can also leave the system low on refrigerant.
The same hose also fits the 2003-2006 GMC Sierra 1500 and the 2003-2006 GMC Sierra.
