My "low coolant" warning light often comes on when I'm driving. The coolant in the Rad is topped right up to full, and as far as I know, doesnt leak. Any ideas why the light would come on, even though the coolant levels are fine? thanks in advance.
Common occurence. Remove the sensor and clean the two terminal ends. If the malfunction continues, replace the sensor, unplug it, or live with the light.
