| 2061369/1 | 2020-12-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Engine overheating - Warning on the DIP - V8 Kovomo. Customer statement / workshop findings: -Customer reports an engine overheat warning on the DIP -Engine overheats -Unusual cooling fan operation at high temperatures -There are no signs of coolant leaks both internally or externally Technical background: To heat the engine as quickly as possible during cold starting, delivery of coolant by the coolant pump is interrupted in the warm-up phase by the solenoid for the mechanical coolant pump. The solenoid is designed to cut off the vacuum supply to the coolant pump when the engine reaches the maximum temperature, the vacuum cut off allows the engine to start circulating coolant by retracting a sleeve which is situated around the coolant pump impeller. When the solenoid is at fault (sticking open) the vacuum supply is constant, this allows the sleeve to stay in position around the impellor which leads to the symptoms described within the Customer statement/Workshop findings section of this TPI. |
