Beck/Arnley Engine Cooling Fan Switch P/N:201-1801
Keep your Honda's cooling fan cycling on cue with the Beck/Arnley Engine Cooling Fan Switch, part number 201-1374 (also written 2011374). This thermo fan switch installs as a direct-fit replacement for the 1986-1989 Honda Accord and 1986-1991 Honda Prelude — see the Buyer's Guide tab for engine-level fitment. As a temperature-sensitive switch, it closes the electrical circuit to the cooling fan (or fan relay) once coolant reaches its set temperature, then opens again as the coolant cools, helping the fan cycle at the right time to manage engine temperature.
If a failed switch is the cause, common signs include the cooling fan not turning on and the engine running hot, or a fan that runs constantly.
