Keep the electric cooling fan cycling on schedule with the Standard Ignition Engine Cooling Fan Switch TS-133. It installs as a direct-fit replacement for the 1983-1986 Nissan Pulsar NX, 1984-1985 Nissan Sentra, 1985 Nissan Stanza, 1986 Nissan Tsuru, and 1982-1984 Porsche 928.
- Temperature-controlled switching: senses engine coolant temperature and closes the circuit to switch the electric cooling fan on as the coolant heats up, then opens to shut it off.
- Restores automatic fan control: reconnects the fan's on/off signal so the cooling system can regulate engine temperature as intended.
- Direct-fit replacement: designed to replace the original switch on the listed applications.
If a failed fan switch is the cause of your problem, this replaces it. Signs the switch may need replacing include an electric cooling fan that never turns on and lets temperatures climb, or a fan that runs constantly. Because overheating and fan-control issues can have other causes, diagnose the circuit before replacing the switch.
