Signal your radiator fan to switch on at the right coolant temperature with the Beck/Arnley Engine Cooling Fan Switch (201-1499). This thermo fan switch drops in as a direct-fit replacement for many vehicles, among them the 1989-1992 Dodge Colt, 1990-1993 Plymouth Laser and 1992 Eagle Summit. See the "Vehicles it fits" section for the full list and engine-specific coverage.
A cooling fan switch is a temperature-sensitive switch that closes the fan circuit once engine coolant reaches its set-point, telling the cooling fan to run, then opens again as the coolant cools. If a failed switch is why your fan won't come on or runs constantly, this replaces it—diagnose the circuit first.
- OE form, fit and function: designed as a direct replacement for Original Equipment applications across foreign nameplates.
- Application specific: check the catalog data and confirm fit for your vehicle before ordering.
- Diagnose before you replace: professional diagnostics are recommended for a successful repair.
- Verify the circuit: check cooling fan motor current draw, control module/relay function, and the electrical wiring and connectors.

Frequently Asked Questions
What does the Beck/Arnley 201-1499 do?
It's a temperature-sensitive cooling fan switch that closes the fan circuit once coolant reaches its set-point, signaling the radiator fan to run, then opens again as the coolant cools.
Is this the right Laser switch for a 1990-1993 Plymouth Laser?
Yes. It's a direct-fit replacement for the 1990-1993 Plymouth Laser, along with the 1989-1992 Dodge Colt and 1992 Eagle Summit. See the "Vehicles it fits" section for the full list.
My cooling fan won't turn on—is this the fix?
Possibly, but diagnose first. If a failed switch is why the fan won't come on or runs nonstop, this replaces it; also check the fan motor current draw, relay/control module, and wiring.
Is this a direct replacement for the original?
Yes. Beck/Arnley builds it to match OE form, fit and function for foreign-nameplate applications, so it installs like the original. Confirm the application against the catalog data before ordering.
What part numbers does it interchange with?
It replaces C1808, 1S4426, 1435049, TFS550, TFS550P, MB356704, FS8474, 8474, TS206, TS371, and SW590.
