Four Seasons A/C Evaporator Core P/N:54996
Four Seasons 54734 front A/C evaporator core for the 1998-2000 Toyota Sienna cools cabin air as refrigerant flows through its serpentine aluminum core.
Weak cooling, a musty smell from the vents or refrigerant loss can mean the evaporator core is leaking or clogged. A low refrigerant charge, a failing compressor or a blower problem can be behind the same signs too, so find the cause before you buy a new core.
This evaporator core is a direct-fit replacement for the 1998-2000 Toyota Sienna, which takes one. The core design meets or exceeds OE performance and efficiency.
