Four Seasons A/C Evaporator Core P/N:64158
Four Seasons 54431 a/c evaporator core for the 1988-1990 Chevrolet C1500 and other vehicles is the coil inside the HVAC system that cools cabin air as refrigerant passes through it.

It is listed for a wide range of Chevrolet and GMC models, including the 1988-1990 Chevrolet K1500 and the 1988-1990 GMC C1500.
