can someone tell me how to get the low coolant light to go off? (coolant is full) ..ps derf..your the man

 

make sure you conection for the sensor is hooked up (bottom side of the resivour)

 

Also check wiring.....if all is well, sensor inside reservoir tank is either gummed up or has gone bad. Sometimes you can free it up with a reservoir cleaning (empty/remove/soak/retry); sometimes you need to replace the sensor. Not uncommon.
