Maintenance of water passage pipes
it must make sure that these pipes are not subjected to any thing leads to its obstruction, also to ensure the passage of the water inside them.
the function of thermostat is to regulate the entry of water as needed within the engine parts in case of increasing temperature.
Maintenance of thermostat
This device needs to be maintained on a regular basis along periods ranging from four to six months and maintenance is carried out by opening the device and clean it well with fresh water to remove residual salts deposited.
C - The fuel system
It is the most systems that must be preserved and consists of several parts, and requires accurate adjustment and maintenance to all its parts, because any defect or fault in one of its parts may cause the engine to stop.
The fuel system consists of the following Parts:
1. Fuel tank
2. Fuel pump Hose
3. Fuel filter
4. Fuel pump
1 - Fuel tank
it is the starting point for the fuel system where the fuel and oil are mixed at a ratio of 50:1 L (1 oil liter per 50 liters of fuel), knowing that the fuel tank capacity is (25 liters) so it needs to add 1/2 liter of the engine oil. Due to increase of temperature, it is preferred to increase the ratio of the oil to be 3/4 liter. In the case of the new engine, the ratio of oil to fuel should be 1:25 liters.
There is a filter in the fuel tank to maintain the cleanliness of the fuel. The tank prevents evaporation of the fuel and keeps it.
NOTE: The functionality of mixed fuel with oil is to reduce the rate of friction inside the engine, evaporation of fuel and the high temperature.
