Four Seasons 56419 a/c refrigerant suction hose for the 2003-2004 Chevrolet Silverado 2500 and other vehicles is a suction line hose assembly that carries refrigerant on the return side of the A/C system.
- 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
Weak cooling, oily residue at the crimped fittings or a cracked hose can mean the suction hose is damaged, though other A/C parts leak or fail in similar ways. With the engine off and cool, look the hose over for those marks first, and leave pressure and leak testing to a shop.
The 2005-2006 Chevrolet Silverado 1500 HD and the 2002-2006 GMC Sierra also fit, and the hose is listed for a wide range of Chevrolet Silverado and GMC Sierra models. If your truck isn't named here, look up its year, model and engine in the "Vehicles it fits" section.
