2. Inspection and Adjustment (Unit: liter) Lube oil capacity may differ from the above volume depending on an engine installed on a machine unit. (b) Replenishing oil pan with lube oil If the remaining engine oil level is low, fill the oil pan with the specified engine oil to the specified level through the filler port. [NOTICE] The oil should not be overfilled to exceed the upper limit line. Otherwise a naturally-aspirated engine may intake lube oil in the combustion chamber during the operation, then white smoke, oil hummer or urgent rotation may occur, because the blowby gas is reduced in the suction air flow.
In case of turbo-charged engine oil may jet out from the breather or the engine may become faulty. (4) Coolant water Inspection Daily inspection of coolant water should be done only by Coolant recovery tank. z Never open the radiator filler cap while the engine and radiator are still hot. Steam and hot water will spurt out and seriously burn you. Wait until the radiator is cooled down after the engine has stopped, wrap the filler cap with a rag piece and turn the cap slowly to gently release the pressure inside the radiator. z Securely tighten the filler cap after checking the radiator. Steam can spurt out during operation, if the cap is tightened loosely.
(a) Checking coolant water volume Check the coolant water level in the Coolant recovery tank. If the water level is close to the LOW mark, open the Coolant recovery tank cap and replenish the Coolant recovery tank with clean soft water to the FULL mark. Standard The water level of the Coolant recovery tank shall be between the upper and lower limit lines. (b) Replenishing engine with water If the Coolant recovery tank water level is lower than the LOW mark, open the radiator cap and check the coolant water level in the radiator. Replenish the radiator with the coolant water, if the level is low. z Check the coolant water level while the engine is cool.
Checking when the engine is hot is dangerous. And the water volume is expanded due to the heat. z Daily coolant water level check and replenishing shall be done only at the Coolant recovery tank. Usually do not open the radiator cap to check or replenish. 24 Model Total volume (L) Effective volume (L) 3TNV82A 5.5 1.9 3TNV84(T) 88 6.7 2.8 4TNV84(T) 88 7.4 3.4 4TNV94L 98(T) 10.5 4.5 4TNV106(T) (CL class) 14.0 9.0 4TNV106(T) (VM class) 14.0 7.5
