My 2002 cadillac sedan deville low coolant level message comes on. I chercked it myself and it is O.K. Could this be a dirty sensor?

Bad coolant level sensor, should be in bottom of readiator or in coolant resevoir/overflow tank. Cheap at parts store!

Check the fan to see if it is going on. On my 1997 Cadillac Deville Limousine I had to have the 2 fans, and 3 relays replaced, as well as the wiring contacts for the relays at an auto electric shop for about $700 last fall, but it has been running cool since then.

Why replace the radiator it's just a bad sensor. Get the Haynes repair manual on your vehicle look up the water level sensor testing and replacement steps. The sensor probably cost around $30 and I doubt if it takes more than 30 minutes to replace.
