Cooling System Problems And Solutions

The cooling system is a very important system to prevent overheating in this system.Cooling system problems and solutions are discussed below.



Cooling System:

If the middle combustion of the cylinder is not controlled, it will be impossible to run the engine. Receives up to 40% of the heat and helps the engine to run normally.
There are two main types of calling method used to keep the engine cool.
 Such as 
1. method of cooling with the help of air
2. method of cooling with the help of water.



Cooling method with the help of air:
Air cooling engines are cars that use air to cool their engines. Such as motorcycles, small engines, airplanes, etc.


Cooling method with the help of water:
The water cooling system is used in cars that use water to cool the engine. The water cooling system is used in most of the cars in the world.

Some important components of cooling system are discussed


Radiator:

It contains about 10 liters to 13 liters of water. This water should be completely clean. For example, rivers, rain, or mineral water should be given. Tubewell water cannot be given because it contains a lot of iron. Tubewell water destroys the radiator core or tubes in a short time. Never drive without opening the radiator cap. The opening pressure of this cap is 0.5 to 0.9 bar.



Thermostat valve:

It works a lot like a switch gate, meaning that the engineer controls the flow of water according to the temperature of the water flowing through the water jacket. If it is not allowed to drive the car, the life of the engine will be reduced. It starts at 74 degrees Celsius and opens completely at 90 degrees.

Solutions

01.

The engine is overheated.

  • First of all you have to test the cooling method.
  • Radiators are dirty or the tubes are jammed with dirt.
  • The water jacket is jammed with rusty dirt.
  • The fan is broken or not working.
  • Loosen or loosen the pump belt.
  • Hose pipe closed or bad.
  • The thermostat valve is not working properly.
  • The impeller or shaft of the water pump is broken.
  • The air cleaner is dirty or obstructed.
  • There is more or less engine oil.
  • If the injector or nozzle is damaged.
  • If the timing of the fuel pump is not correct.
  • If the cylinder gas kit leaks.
  • If the valve timing is not correct.

  • Cleaning or repair.
  • Need to be cleaned.
  • Need to change.
  • Change or tighten.
  • Need to clean or change.
  • Clear or change.
  • Oil should be given as required.
  • Repair or replacement.
  • The timing needs to be right
  • The head bolts should be tightened well.
  • And gasket timing must be correct.

02.

Leakage and noise are created at the base of the water pump.

  • The seal on the water pump may be damaged.
  • The shaft of the pump may break.
  • The pump bearings may break.
  • Puli has lost one line.

 

  • The seal needs to be changed.
  • The shaft needs to be changed.
  • The bearings need to be changed.
  • Repair or replacement.
  • Repair or replacement.

03.

Water leakage or water is reduced.

 

  • The radiator may have a top-down hole or a core or tube hole.
  • Hose pipe holes or connections may be loose.
  • Drain plug leaked or damaged.
  • If the radiator cap is damaged or not.
  • If the head gasket is bad.
  • If the engine block is cracked.

  • The hole needs to be repaired or replaced.
  • Need to change or tighten well.
  • Need to repair or change. Need to change.
  • Need to change.
  • Need to repair or change.




There are 7 important aspects to check when setting up an engine


  1. The pressure of the good pump needs to be checked.
  2. You need to check the clearance of the thrust washer when setting the crankshaft.
  3. Engine timing needs to be checked.
  4. The clearance of main and big-end bearings should be checked.
  5. Tapate clearance needs to be checked.
  6. Clearance of the piston, piston ring, the liner should be checked.
  7. Check if the engine valve is leaking. And the head bolts have to be tightened well.
