Sensor Question
I have a 1989 L98. What sensor is located on the driver side of the engine block, between the front 2 spark plugs. I think it is a coolant sensor. The connector is broken at the pigtail and on the sensor. Does anybody have part numbers? Thanks.

Both Corvette American & MAM offer that connector in a package with a lower temp aux fan switch at around $35-$40; maybe Vette2Vette (Vette bone yeard) has just the connector & cable to the fan relay.

. Auto System Kicks Fan(s) On At 200 Degrees And Off At 185
. Replaces Existing Auxiliary Fan Switch
. Handy Conversion Harness Simplifies Wiring Connection
Low Temperature Electric Cooling Fan Switch helps maintain optimum performance operating range while keeping your Corvette's engine cool. Conversion Harness is required for all 1990-91 Corvettes and 1985-89 Corvettes with single fan. A new harness is recommended on all, but is an optional replacement for cars with auxiliary fan. Instructions included.

only time mine ever came on was when the green wire played on the manifold and the insulation melted...thought for a second that something expensive died from the noise level, shut engine down and noise seemed even louder...wtf
now have a manual over ride switch tied in, have yet to need it.

Newbie here with a fan switch sensor issue - I want to lower the cooling fan cycle on my 1994 LT-1 to 210deg. on / 195deg. off. Which leads to my next question:
Is the 1994 LT-1 main radiator fan being controlled by the engine computer reading a variable resistance temp sensor, or by a thermostatic on/off switch unit like what it sounds like is being described for the 1989 C4?
If it's a switch, I'm going sensor shopping for a lower temp switch. If its ecu controlled, then I'm gonna have to get more creative...

anyone? anyone? bueller? bueller?
Guess I figured it out on my own... The fans receive instructions not from a fan switch type sensor, but by the pcm after reading a temp value from a variable resistance sending unit.
Damn... guess I'm going to have to add an aftermarket thermostatic control to one of the fan relays and series it in with the existing relay wires from the pcm.
