3.6 Cooling System
In order to ensure excellent engine life and cooling performance, the installation of the
radiator must meet the following criteria:
When installing the radiator, install the vibration absorber.
Figure 3.6 - Vibration absorber arrangement
If the engine works in a soundproof box, sealing rubber should be installed around the
radiator to prevent the hot air beyond the engine from flowing back into the cool air
entrance.
Radiator grounding measures must be taken to eliminate potential difference and pre-
vent electrical corrosion (aluminum radiator do not require).
The surface of the radiator should not be covered by other components, and the direct
wind crossing area should be greater than 80% of the radiator surface.
The minimum diameter of the coolant pipe between the engine and radiator is 45mm.
3.7 Lubrication System
Users must follow the requirements in
6.2 Lubricant Recommendation.
To get a good performance of the engine lubricant system, the engine should be mounted on
the chassis within a permitted angle. The angle limitation is 5
°
in front-rear direction and 15
°
in left-right direction.
