refers to a boil engine operating temperature reaches an excessively high temperature auto For normal operating temperature range.
1. Boil causes
the cause of many automobile boil, in addition to the hot weather, air conditioning and cooling overload operation component failure also make the car outright.
2. How to prevent boil
for automotive cooling systems conduct a comprehensive inspection is the primary way to prevent boil. Check the cooling fan is working properly, whether the tank leaks, whether the lack of cooling liquid, if water leakage, the need for timely repair or replacement, if the tank needs to replenish the lack of liquid, muddy deterioration occurs if the coolant should be replaced.
Further, Common coolant containing water vapor barrier layer is formed in the cylinder wall of the engine, prevents heat dissipation, it will lead to engine failure, shorten engine life.
For some inexperienced or not know enough about the car of a friend, 4S shop regularly go to a regular maintenance and troubleshooting is elected on it.
3. boil Mistakes
boil when opening the lid immediately after adding the boiling water within the radiator, will have a certain internal pressure, wherein the outlet when added immediately open the radiator, the hot water will outwardly discharged, causing burns.
Therefore, the owner should not boil immediately after opening the lid with water.
immediately after flameout after
boil some drivers found boil, turn off immediately think of. To know: the reason why the engine boil water because the tank temperature is too high, this time when the flame, parts are in the expanded state, each with a small gap, the soft metal can cause some off the flame, some may even cause sticky cylinder . So after the discovery boil, do not turn off immediately, should remain idle. If the car has stalled, the car should immediately shake the handle to prevent sticking cylinders.
when the engine temperature is too high, the engine poured with cold water and some friends found the engine temperature is too high, then the engine block, cylinder head and poured cold water to cool. Little do they know the consequences are very serious,This may cause the engine block because the quenching and burst, causing incalculable consequences. After
4. The correct way to boil
found that boil water tank should be parked in a cool place, let the car idle for a minute, until the water temperature has dropped is no longer boiling, then wet towel to do hand pad, radiator cover with water first to open a little bit open and release water vapor, wait a moment and then fully open.
To the face while avoiding the above filler opening, to prevent scalding hot water discharge face when the coolant was added, and the installation of the tank is preferably the same type antifreeze, not arbitrarily add water, unless when no antifreeze after emergency treatment, should be promptly returned to the repair station to replace the antifreeze.
