Four Seasons A/C Evaporator Core P/N:54998
Four Seasons 54509 A/C evaporator core for the 1986-1988 Buick Electra and other vehicles cools cabin air as refrigerant flows through it. The core design meets or exceeds OE performance and efficiency.
Weak cooling or an oily film around the evaporator case can mean the core is leaking refrigerant. These signs alone do not prove the core is the problem, since a low refrigerant charge can also leave the air warm.
The 1986-1988 Buick Electra, the 1986-1988 Buick LeSabre and the 1986-1988 Oldsmobile 98 are among the cars this evaporator core fits, along with others. To check your own car, open the "Vehicles it fits" section and look up your exact model and engine. The 1986-1988 Buick Electra takes one.
