Then, you should remove the coolant reservoir nut. With the coolant reservoir lifted, use the Hose Clamp Pliers (J 38185) and reposition the coolant reservoir outlet hose clamp. Remove the coolant reservoir outlet hose. Disconnect the sensor for the coolant level electrical connection and pull out the coolant reservoir. Installation, locate the coolant reservoir in position, and fit the coolant level sensor electric connector. After the coolant reservoir is lifted up, fix the coolant reservoir outlet hose and tighten the hose clamp with the Hose Clamp Pliers (J 38185) in its new position. Install the coolant reservoir nut while tightening it up to 10 Nm (89 inch lbs.). Adjust the underhood junction block bracket into location and insert the underhood junction block bracket nuts (1, 2) and tighten them at 10 Nm (88 inch lbs.).
