Note:

1- If motor goes out of order it idles

2- If there is heat on motor open the radiator  tap by bleeding 

3- If cooling system decrease the level of water  gaskin of cylinder cover may be ripped or abduct from radiator trunk

4- If water get in to engine oil cylinder seal is burnt

5- If heat is increase oil is become thinner and engine is declining

6-If heat gauge is nor working gaugge will be out of order or connection line is split off

7- If engine doesnt reach working temperature afer vehicle works thermostat will be out of order If thermostat is open engine doesnt heated.
8- Cooling system water must be checked daily. Water must be clean as drinkable

16-Warm water must be add engine if itsa water level increasin due  to heat.

CHARGING SYSTEM

Aims:

Charge the battery during engine works and feed the receivers.

Parts:

1- Alternator : To translate mechanical energy to electrical energy during engine works.Charge the battery and fill it up.

2- Regulator:To prevent damage of system by tune the electricity which produce by alternator.

3- Charge Gauge: To show that system is working or not

Working:

When the key switch open oil and charge lambs are lighted. Fade when engine goes on Charging gauge shows that system is working or not to driver.when the charge lamp is lightened stop the engine
