Bring the cold-air side of your classic Mercedes-Benz A/C system back to life with the Four Seasons Tube & Fin A/C Evaporator Core 54131. Inside the dash, the evaporator core is where low-pressure refrigerant expands and evaporates, absorbing heat from cabin air the blower pushes across its fins — cooling and dehumidifying the air before it reaches the vents. This one drops in as a direct-fit replacement for a range of Mercedes-Benz models, including the 1973-1980 450SL, 1973-1980 450SEL, 1975-1976 280S, 1977-1980 280SE, 1981-1985 380SL and 1986-1989 560SL, all cataloged for [All] engines — see the Buyer's Guide tab for the full list.

  • Tube & fin aluminum core: core design built to meet or exceed OE cooling performance and efficiency.
  • Optimized refrigerant flow with an application-specific design matched to the listed vehicles.
  • Flare-fitting connections: female inlet fitting and male outlet fitting.
  • Includes the gaskets, O-rings or seals called out to complete the replacement.

Backed by over 50 years of Four Seasons mobile A/C experience.

Frequently Asked Questions

What does the A/C evaporator core do?

It's the cooling element inside the dash: refrigerant evaporates within the core and absorbs heat from cabin air the blower pushes across its fins, cooling and dehumidifying the air sent to the vents.

Which vehicles does the 54131 fit?

It's cataloged for a range of Mercedes-Benz models, including the 1973-1980 450SL/450SEL/450SLC, 1975-1976 280S, 1977-1980 280SE, 1981-1985 380SL and 1986-1989 560SL. See the Buyer's Guide tab for the complete list.

What is this evaporator core made of?

It uses a tube-and-fin aluminum core design built to meet or exceed OE cooling performance and efficiency, with optimized refrigerant flow.

Does it include seals for installation?

Yes — the core is supplied with the gaskets, O-rings or seals called out to properly complete the replacement. Confirm you have any additional fittings your service procedure specifies.

What are signs the evaporator core may need replacing?

Weak or no cooling, an oily refrigerant leak at the evaporator, or musty vent odors can point to a failing core. Diagnose the A/C system first, since these symptoms can have other causes.
