85-89 with B4P, 90-95 All. The stock C4 Corvette cooling system runs inherently hot. GMP has the solution. We offer electric cooling fan switches in four different temperature ranges. The switches will turn on the main fan, auxiliary fan or both at a lower temperature. Lower coolant temperatures will maximize engine performance and reduce engine wear. Each kit comes complete with switch, harness, hardware and instructions for easy installation. 244455 and 244074 switches are recommended for stock applications. 244198 and 244381 switches are recommended for highly modified cooling systems and/or off-road use only.
Note: Can be used in 1996 but the "Service Engine Soon" light will come on and a "DTC" will set. The computer is telling the driver the fan(s) have come on before the factory-programmed setting.
