How Motorcycle Radiator Works and How to Repairs It
Motorcycle — The components that
exist on the motorcycle radiator is very much, it requires maintenance to keep
the radiator working optimally. Sometimes there are users who use ordinary
water for radiators, but this is not recommended by motorcycle manufacturers.
Because it can cause rust on the engine, in general the water will boil at a
temperature of 100 degrees Celsius but by using the boiling point coolant to
increase can exceed 150 degrees Celsius.
Radiator Function on Motorcycle
Radiator is a component on a
motorcycle engine serves as a heat release absorbed by cooling water after
rotating inside the engine, consequently coolant temperature becomes down.
Radiators are very important for machines that have a large capacity, because
without radiator the engine will produce excessive heat. So the engine power is
not maximized, and worse the piston will lock because of it.
Motorcycle Radiator Components
Radiator
The radiator consists of two water
tanks, namely the upper tank and the bottom tank, in the upper tank there is a
coolant charging hole into the radiator inlet. While the bottom tank there is
an outlet to the engine and the exhaust pits.
In the radiator often occurs damage
due to a collision so that the radiator leaks, broken or bent. Other causes
because of the life of the radiator, can it be fixed? Depending on the severity
of the damage.
If the leak can be slightly
repaired with mixed glue that is usually sold in the spare part store, or use a
special liquid radiator stop leak. This fluid serves to patch the fine leak
inside the radiator, this liquid contains the active substance and film layer.
Some brands that are super x, Prestone, Wynn, Rislone, Bar's Leak and others,
if seriously damaged the last step to take the replacement.
Coolant
Coolant is a fluid that serves to
keep the engine temperature to be stable and not experiencing excessive heat.
Coolant is required to have properties that can keep the engine temperature and
does not cause rust and damage to the engine. Radiators should not use regular
water, but motorcycle manufacturers recommend using special radiator water or
coolant. Because ordinary water does not contain anti-rust but cause rust. And
the boiling point of the water is only 100 degrees centigrade, while the engine
temperature can reach 115 degrees so all ordinary water will evaporate.
While the coolant has a boiling
point and freezing point better than ordinary water, and each coolant has a
different substance content so it is not advisable to mix it. Coolant may be
replaced with a different brand as long as it is watered thoroughly, so there
is no mixing of the substances contained in each coolant, as each manufacturer
has their research.
Reservoir
The reserve tank for the coolant
that is usually positioned outside the radiator, function so that the coolant
has a long period to increase the amount of coolant on the radiator.
Radiator Hose radiator serves as a
rotation of the coolant, so if the radiator hose damaged will cause leakage
coming from the hose.
Radiator Pump
Serves to speed up the coolant
rotation in the cooling system, so that the cooling process becomes faster and
the temperature are maintained. Damage to the radiator pump usually occurs on
the rubber seal between the engine oil and water radiator damaged, consequently
coolant will run out because mixed with engine oil. This is very dangerous for
the performance of machine because it causes severe broken.
If the coolant runs out quickly and
there are no leakage from the outside of the radiator component, there may be a
leak in the rubber seal between the engine oil and the coolant. Actually this
can be estimated by measuring the engine oil duty when performing a
replacement, if when dumped engine oil dosage is more than the manufacturer's
provisions. Example Honda SH150i has a dose of 800 milliliters to 1 liter so it
can surely coolant mixed with engine oil.
Radiator Fan
Cooling fan located around the
radiator because it is useful to help cool the coolant, the way the fan works
there are two electrical systems and mechanical systems. The electrical system
of the power source comes from the battery, which rotates when the temperature
sensor expands so that it touches the metal from the electric fan switch. The
temperature sensor will expand if the engine temperature has reached 105
degrees Celsius, so if less than that temperature the radiator fan will not
rotate.
While the radiator fan of the
mechanical system rotates following the rotation of the crankshaft, thus simply
adding the load on the engine rot although only a few grams. The advantages are
rarely damaged because of the way it works that simple.
Close Radiator
The main function of the radiator
cap is to keep the radiator water from spilling out, the radiator cap also
limits the expenditure of water vapor during coolant inside the boiling
radiator. This limitation occurs when the radiator cap gets pressure by water
vapor if it reaches 108 - 137 kpa (1,1 - 1,4 kgf.cm2,16 - 20 psi).
Thermostat
Thermostat is an automatic valve
that works to regulate the temperature of the heat on the machine, how to limit
the amount of coolant for the machine quickly reach the working temperature of
80 degrees Celsius. How it works when the cold engine will close the coolant
lane coming from the bottom radiator to the engine. Then when the hot coolant
path from the bottom radiator will be opened slowly if the engine temperature has
reached 85 degrees Celsius, and the coolant path from the top radiator will be
closed.
How to Take Care of Motorcycle Radiators
Always check the radiator's
reservoir tank, do not let coolant be below the lower limit or left blank.
The addition of coolant should not
cross the upper or upper limit, to cause the coolant to spill through the
respirator tank breathing hole.
Drain coolant every km 16,000 or 1
½ years, so as not to cause the crust on the radiator path and maintain coolant
performance.
Wash with water radiator grille and
spray using wind spray gun to keep dust and dirt lost, otherwise fix the grille
if there is a crook.
Watch the speedometer if a red
light is on, meaning the motorcycle is overheated.
OK bro so long a brief explanation,
the end of the word priority to drive safety and not arrogant street highway. salam satu hati...
