where is the sensor to replace it? It is constant blinking. How do you empty coolant reserve tank? -
Answer 1
Remove it! Pretty straight foward to see how, couple of screws then disconnect hose(s) pull up on it. Replace sensor or the tank assembly. -

seek help from your mech -
Answer 3
Have vehicle scanned for codes. The low coolant light may not be related to the service engine light at all. Try taking a rubber mallet or hammer and tapping on the overflow tank (not too hard) around the sensor and see if it will unstick itself. -
