MBE 900 ENGINE 2007 OPERATOR'S GUIDE NOT fill beyond the maximum fill level on the dipstick, since overfilling may result in high oil consumption and possible severe engine damage. If necessary, add additional oil through oil fill cap located on the top of the engine see Figure 15. HOT COOLANT To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure. Checking the Coolant Level (Cold Check) 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. 2. Then, with the coolant temperature above 50°C (122°F), recheck the coolant level. 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. 3. Add more coolant if necessary. Open the heater valves (if equipped) before adding coolant. 4. Do not close the heater valves until the engine has been run briefly and the coolant level again checked and corrected as necessary. NOTE: For more information, refer to the ”MAINTENANCE” section.
Checking the Coolant Level (Hot Check) Monitoring Engine Operation Check coolant level as follows: 1. Allow the engine to run for approximately five minutes at a moderate speed. While the engine is operating, monitor the battery charge indicator light, the oil pressure and avoid excessive idling. All information subject to change without notice.
