MBE 900 OPERATOR'S GUIDE Checking the Coolant Level (Cold Check) NOTICE: Correct torque on the high pressure lines is critical. Incorrect torques could result in leaks or lack of power due to restricted fuel flow. Check the coolant level as follows: 1. Ensure that all coolant plugs in the bottom of the radiator and on the radiator outlet pipe are secure and tight. 1. Make sure that all high-pressure and low-pressure lines are securely tightened. 2. Check the coolant level. The cooling system is correctly filled when the coolant is between the maximum and minimum marks on the surge tank. 2. If equipped with a hand pump on the fuel/water separator, work the hand pump 50 times. 3.
