w202 c220 Petrol 1994 - Coolant light on

[MSinghMerc]

Dear Team,

I am coming along smoothly with my project smoothly and I have this light that comes on the dash, left side, for coolant first photo,

i have done the following:

1. changed the washer liquid sensor , installed a new one and also removed container and washed out- also checked voltage on the connector to this level sensor.

2. changed the sensor on the coolant container, checked the voltage to the connector.

3. on the Thermostat housing - i have only changed the single pin sensor, the middle one.

I have used my icarsoft - but it does not pick this issue up as its not an electronic issue,

please can you advise what else can be done, to remove the coolant light?

thank you

Wiring will have rubbed through and corroded somewhere??

Dear Dodipops,

wireless eroded maybe going back to the dash?

Does the car have an electric radiator fan?

No it’s usually behind the bumper, follow the wiring back from the washer bottle sensor and keep looking until you find it
