Standard Ignition Engine Oil Temperature Switch P/N:TS-618
Standard Motor Products
Standard Ignition TS-159 oil temperature switch for the 1984-1989 Chevrolet Corvette makes electrical contact once the engine oil reaches its set temperature. The engine oil temperature switch then passes that signal to the fan controller.
A fan controller problem, damaged wiring or a loose connector can be behind a cooling fan that runs at the wrong time or not at all, and so can a worn switch. Find the cause before buying; if this switch is the cause, this one replaces it.
This oil temperature switch fits the 1981-1982 and 1984-1989 Chevrolet Corvette, and the car takes one.
