4.3 Installation of the diesel engine
When installing, it should be ensure that the centerline of diesel engine crankshaft is concentric with the axis of
input shaft of driving device (gear box, alternator etc.) and elastic coupling should be used to ensure that there is
noadditional axial foron the crankshaft caused by the installation.
4.4 Preparations for Diesel Engine Starting
1) Check coolant level
Check the coolant level through the glass window of expansion tank, and add coolant from the filler port if
necessary. When the engine is still hot, beforeopen the filler cap with relief valve and bleed button, please always
press down the bleed button first to release the hot air. It is prohibited to add a large amount of coolant when the
engine is relative hot; otherwise, the related parts of diesel engine may get damaged due to sudden excessive
temperature change. The coolant (water) should be added via the filler port until it overflows.
Start the engine, and when the engine is running (at 1000 r/min), continue to add coolant till the liquid level is
stable, and then close the filler cap.
2) Check fuel level
If the engine has been installed on the vehicle, please turn on the power supply switch, and check fuel level
through the fuel meter or check the fuel tank directly.
3) Check engine oil level
The engine oil level shall be locatedat between the upper and lower markings of the oil dipstick. If necessary, add
engine oil from the filler port.
4) Check liquid level in DEF tank
