Hi All,
When my coach is running, the 'Engine Water' light (coolant level) will
often flicker on and off. The actual level of coolant in the radiator
is fine. My guess to the most likely cause is the coolant level sensor,
which at $10 or less seems worth trying. Does anyone have any
suggestions?

The guru of Chemicals might have some input on the conductivity of various
concentrations of anti-freeze. You might have a problem with the additive
package, or, you might have a problem with the sensor electronics in the
warning light circuitry.

If I remember correctly that sensor is nothing more that a brass or steel probe sitting in the water / coolant. I will go with the others here and say your problem is the wire going to it or the connection.
