What should the coolant temperature be on a corvette?

The main fan is ECM controled to come on at 227*. If you have the aux fan (found under the front bumper infront of the radiator and is controled by a switch in the right head between #6 and #8 plugs), it will come on at 238*. GM designed these cars to run a little hotter than most for emissions purposes.

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 coolant temp be when engine is hot?

With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. 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.

What happens when your coolant temperature sensor is bad?

The engine is very sensitive to wrong air-fuel mixtures at idle and this is a condition when you might notice that something is wrong with your engine coolant temperature sensor. The engine coolant temperature sensor can have a hard impact on the air-fuel mixture. A bad air-fuel mixture can also cause the engine performance to drop drastically.

How does reverse coolant flow work on a corvette?

In addition to reverse coolant flow, there are several other improvements in the LT1 cooling system over conventional engines. 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.

What to do when your corvette runs hot?

On the L98 few recommend to max-lift the front of the car. The majorities do this, fill the system, start the engine and when the thermostat opens and the level in the radiator drops, keep filling the radiator and then raise the engine RPMs to around 2,500 RPMs and add more coolant. Then replace the pressure cap before releasing the throttle!
