I have 1999 chevy venture with a 4.3L V6 engine. The coolant light is on. I have checked the water level in the radiator and the coolant container. The radiator is full and the coolant container has coolant in it. I have concluded that I must have defective coolant sensor. I have replaced the coolant sensor (in the radiator) and I have still have a low coolant light on. I have unplugged the wire warness connection and test the voltage at the connector. I got 14 volts. I have tried another brand new sensor that I immersed in a cup of coolant and got the same reading, i.E. Low coolant light on when the sensor is emersed in coolant and connected to wire harness. What is the problem here? Any suggestions? Thanks!
