Where are the coolant sensors on a C4 Corvette?
Where are the coolant sensors on a C4 Corvette?
Sensor Values and Location. C4 Corvette Sensor Coolant Temperature. 185 Ohms @ 210F, 3400 Ohms @ 68F, 7,500 Ohms @ 39 F. Front of engine, below Throttle Body. 1985-91 Located Under Plenum. 1992-96 Located In Water Pump.
What should the temp of the coolant sensor be?
Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.
What kind of fan control does a 1994 Corvette have?
1994-1996 have three relays: primary, secondary and one relay for half speed fan operation. 1990-1993 Corvettes will have the dark green or blue wire spliced into the fan relay with the dark green/white striped wire for primary fan control. This works best for stock or mildly modified engines.
Where is the relay wire for a corvette cooling fan?
Locate the dark green/white wire at the relay connector. This will make both cooling fans come on simultaneously, meaning less run time for both fans if the cooling system is in good condition. Route the cooling fan harness dark green or blue wire to the main fan relay (near the battery).

Where is the low temp fan switch on a 1996 Corvette?
1985-1996 Corvette Low Temp Cooling Fan Control Switch would be installed in this location (driver’s side cylinder head between cylinders 1 and 3). Cut the dark green /white wire at the inner fender well.
What should the cooling temperature be on a 1984 Corvette?
1984 Corvettes will have the most noticeable improvement, as the factory cooling fan setting is 238 degrees. Lower temperatures will work at the expense of fuel mileage. There are various cooling fan control switches available to turn the cooling fans on earlier than the factory ECM or PCM controlled settings.
Where does the coolant go in a Corvette LT1?
The LT1 has absolutely NO water running through the intake manifold! Conventional cooling systems have passages in the intake manifold which allow coolant to crossover from one side of the engine to the other. In the LT1, coolant crossover occurs in the water pump, which is also where the thermostat is located.
