The low coolant light is from either low coolant level in the reservoir or a defective sensor in the reservoir bottle. Sounds like a speed-sensitive vibration - probably tire balance but could be a bad tire.

For testing purposes unplug the low coolant sensor. If the light still is on you have a short in the wiring. If it goes out either the sensor is bad or, if the radiator or recovery tank has been replaced, somebody forgot to drill out the template hole(s) for the sensor. If this is the case the sensor is dry and "thinks" you're low on coolant. HTH. -Jim

Could the light come on if a fan stops working and what if it goes off for like a houer and comes back on
