Welcome to BuyEvaporatorCore.com, your source for car and truck evaporator cores and the expansion valves that go on 'em.

This website was developed specifically for automotive air conditioning evaporator cores, also known as evaporator coils. As a large volume distributor of affordable evaporators, we saw the need to provide a clean, very specific catalog of these parts.

Using this site, you can search by either an OEM part number, another manufacturer or distributor part number, or by vehicle. Both search controls are on this page.

The air conditioning evaporator core, or evaporator coil is located in the dash or at the back of the engine, and should not be confused with the condenser, which is located in front of the vehicle, right in front of the radiator. The evaporator core contains cold refrigerant that has been pumped through the system. The blower blows air across the evaporator, and heat is removed from the air, resulting in cold, dehumidified air from the vents.

Unfortunately, the evaporator core can develop leaks over time. Sometimes the evaporator drain tube gets clogged, water builds up, and the core can develop pin-hole leaks. Because the evaporator coil is constantly covered with moisture due to condensation, leaks can also develop as a result. Because the evaporator core is on the low side of the system, meaning the refrigerant pressure is very low, evaporator leaks are generally pretty slow, and can be difficult to pinpoint. If there is dye in the A/C system, a clean white towel or diaper can be placed under the evaporator drain tube, and any dye should be easier to spot. We do NOT (nor does any OEM manufacturer) recommend the use of sealants in the air conditioning system; this can cause blockages, damage other components, and require expensive repairs to shop recovery equipment when you end up replacing the system.
