Service Manual for WD10 Diesel Engine 213 Lubrication of Tensioning Wheel Apply general purpose lithium lubricating grease for lubrication of tensioning wheel (refer to GB/T5671-1995) 214 Antifreeze Additive in Engine Cooling System The adopted antifreeze additive is ethylene glycol, and it is allowed to replace it with domestic long-acting antifreeze additive with reliable quality, refer to related description for specific application method. The following two long-acting antifreeze additives in china are recommended:
JFL 336# Long-acting antifreeze additive FD 30# Long-acting antifreeze additive It's important to note that long-acting antifreeze additive should be replaced periodically according to related requirements. Calculation of antifreeze additive (for reference) Coolant amount: 40L (for an engine with radiator) Current application temperature of coolant: -20 o C Required minimum anti-freezing temperature: -30 o C Calculation method: Find the point of coolant amount “40L” on x-coordinate, and draw a vertical line through this point, and point 1 and 2 are the intersections between the vertical line and -20 o C oblique line, -30 o C oblique line respectively.
