93 chevy camaro (overheat)?

Question

I have a 93 carmaro that over heats. I replaced the fan motor and checked the voltage with the key on and it read 14 volts. the car will go over 220 degrees, still no fan. If I turn the a/c on the fan will come on. Iremoved the wires to the temp. sensor and jumped them and still no fan comes on. I need help thanks. Also the thermostat was recently replaced and the radiator was flushed.

Answer 1

you shouldnt have any voltage at the fan unless the relay is activated, the only way the relay can be activated it by the ac signal or the temp sensor. if you jumped the sensor and no fan then the relay could be bad, you could have a ground problem with the fan or the wiring from the sensor to the relay is damaged

Answer 2

I'm not a mechanic- but it could be the fan sensor relay.

If the car overheats again, you might try turning on the heater on full blast. I know it will be very uncomfortable in the summertime, but the heater will draw out heat from the engine compartment.

It would be better for you to break out a sweat than for the engine to be damaged.

You might also check your fusebox, to see if one of the fuses requires replacement.

Good luck.

Answer 4

Try a lower temp, thermostat. or check the relay switch.

Answer 5

Did you check to see if your converter is stoped up that happened to a friend of mine.and if you put in to much antifreeze it will make it run hot.
