A failing switch can show up as an engine running hotter than normal or a fan that does not come on when expected. Before replacing it, look over the switch, its terminal and the connector with the engine off and cool. Corrosion, damage, or a wiring or fan fault can look the same from the driver's seat.
This switch is a direct-fit replacement for the 1987-1993 Ford Mustang.
