Hi,
The "add coolant" light on my 76 Vega is constanly on. I know the radiator is not leaking and there is enough coolant. Seems to me it is a eletrical problem.
I tried to take the wire from the module to the sensor and used a jumper wire and "grounded" it. But still the light is on. The wiring from the sensor to the module looks good.
Maybe I should replace the coolant module in the dashboard?
Is there anyone else who have had this problem earlier?
Please excuse my bad English writing.
Thanks!
