Recently the Coolant Level check lamp has begun coming on and off intermittently. The coolant mix and fill level are good and the engine temp gauge does not register a warmer than usual indication. Any thoughts on what might be the trouble? Thanks.

Suggested Repair

Inspect the coolant overflow bottle level sensor wiring for damage. If the wires are intact, replace the sensor or the bottle if the sensor is integral to it.

Conversation Summary

A 1999 Mercury Sable had an intermittent coolant level warning lamp despite a correct coolant mix and fill level and a normal temperature gauge. The expert advised checking the overflow bottle sensor wires and replacing the sensor if the wiring was intact. A new coolant bottle with an integral sensor was installed and the problem was resolved.
