Four Seasons A/C Evaporator Core P/N:64163
Four Seasons 54586 A/C evaporator core for the 1988-1992 Chevrolet Camaro and other vehicles removes heat from cabin air as refrigerant flows through it.
Weak cooling, a musty smell from the vents or a steady loss of refrigerant can mean the evaporator core is leaking or clogged. A low refrigerant charge, a failing compressor or a blocked orifice tube can be behind the same signs, so find the cause before buying a core.
This core is a direct-fit replacement for the 1988-1992 Chevrolet Camaro and the 1988-1992 Pontiac Firebird. Both take one core, which is what this listing holds. The core design meets or exceeds OE performance and efficiency.
