According to special margin fan clutch was informed that the reason a lot of engine overheating, when this happens, try to check the following aspects in order to identify problems to repair.

First, the fan problem

Fan motor does not move or fan clutch failure, unable to properly cool.

Second, the water pump problem

After long-term use of the pump highly abrasion, wear parts missing off; the only solution is to get a new water pump.

Third, the thermostat block issue

Thermostat not properly switch is usually mechanical failure or incomplete filling the cooling system caused. Update the existing thermostat and the temperature coefficient different from the cause of the fault.

Fourth, the radiator cap issues

If the radiator pressure cap varies, will cause spring loose, not tight lid closed and mouth.

Fifth, exhaust problems

TWC blocked or pipe rupture, causing the exhaust is blocked, causing the engine to overheat.

Sixth, the coolant leakage problem

If the cooling system pipe rupture, causing loss of coolant, the heat is not working properly; such circumstances as long as the change of the new pipe will be able to improve.

Yu-fan clutch special knowledge of automotive cooling system teach you the summer conservation methods:

   In summer, the most common fault automobile cooling system is the "tank boil" making the car broke down, the occurrence of water deficit. With the loss of water and boil the water tank as well as accelerating weakness failure.

   Boil water tank maintenance vehicles, we must first ensure that the vehicle other related components properly, such as using the correct grade of fuel, oil, spark plugs, antifreeze, and adjust the ignition timing and idle air-fuel ratio. In the cooling system further examination of these areas are normal.

   Check the order should be: look at the tank. When the tank cars normally be consistent with the temperature up and down, if the situation occurs half cool the hot side, inside the tank can determine blockage. The tank can be connected to the 2 kg pressure pipes, reverse flushing, severe blockage if a small amount of cleaning agents can be used, taking care to wash the dirt tank and observe for leaks.

   Second, look at the thermostat. Some people think that the removal of the thermostat can prevent the water temperature is high, in fact, as long as the thermostat is functioning properly and does not cause the water temperature is too high, while the engine is running at low temperature for a long time is very harmful; many additional engine thermostat is a two-way effect, when the thermostat is closed, forced to go small cycles of cooling water, and the thermostat is turned on, the small loop closed loop cooling water all go big. If you do not install the thermostat, because the pipeline throttling role of local resistance, the actual flow of a cycle is very little water, but the water temperature rises.
 
    Finally, check the pump. Damage to the pump in three ways: leakage, corrosion lost rpm and impeller. The so-called lost water pump shaft and impeller rotation is with the gap is too large, when the engine reaches a certain speed, the pump impeller can not reach the appropriate speed, resulting in poor circulation. Cooling fan is the main component, and some cars have eliminated the fixed fan, and fan and replaced with silicone electromagnetic clutch. It is characterized by a cold car fan basically does not work, and the maximum amount of heat hot car; major fault silicone fan clutch is leaking, and the main fault electromagnetic fan clutch is the temperature switch is damaged, the line is damaged, the electromagnetic coil damage .

    According to Yu-fan clutch special note, in addition to the heat of the engine cooling water as the medium, the part with the exhaust heat can be dissipated, oil can also take some of the heat, but more air flow around the engine plays an irreplaceable role, so Do not forget to check the exhaust system (especially with a catalytic converter models) are smooth, engine oil, transmission oil cooling devices are in good condition when the check engine overheating. Also near the engine fan wind shield (commonly known as the wind turns) heat convection inside the cabin plays a vital role on the check should pay attention to.

In order to prevent the cooling system fails, you should pay attention to the maintenance of the cooling system maintenance, cooling system include:

1 Check the cooling system is sealed, the tightness of the fan belt, thermostat and cooling water temperature sensitivity of the situation, etc., and keep plenty of cool water.

2, including cleaning the radiator cooling water jacket scale adhesion, prevent scale affect thermal performance cooling system.

    Again: Summer though not freezing, but the automobile antifreeze coolant or to stick with, do not substitute with water, or the occurrence of "boil" phenomenon will increase, not conducive to the heat of the engine.
