Help your electric cooling fan switch on when the engine calls for it with the Standard Ignition switch TS-126, an engine cooling fan switch that senses coolant temperature and signals the fan to run. It is a replacement for the 1985-1988 Nissan Maxima and the 1986-1989 Nissan Stanza. See the "Vehicles it fits" section for engine details.
When coolant reaches the switch's set point, the switch closes its electrical contact and passes the signal to the fan controller. Signs this part may need replacing include a cooling fan that stays off as the engine warms up, a fan that never shuts off, or a temperature gauge that climbs at idle or in slow traffic. These symptoms can have other causes, so diagnose the cooling system before you replace the switch.
