Your car radiator is the primary
cooling mechanism for your engine. A small leak on your Radiator can be
signaling a greater trouble. A cooling system that runs low too often is less
efficient and you can damage your cooling system by letting the coolant level
get too low. Too little coolant flow can be bad, but at normal and high
operating temperatures, the rate at which coolant runs through the radiator
doesn't change the amount of heat that is dissipated by the cooling cores. The
amount of cooling won't be reduced even when the mean temperature of the coolant
rises and flows faster.
Many cheap coolants do not have the
corrosion protection, PH balancing, or sediment prevention that the high-grade
coolants do. These low quality coolants do not have the same additives of name
brand coolants. To help your engine stay cooler, rev up your engine slightly
when you're overheating in traffic jam to help push more air across the cooling
cores and more coolant through the engine.
All water-cooled radiators have an
automatically controlled blower on the radiator. The way the system is supposed
to work is that, after the engine is started, the thermostat on the engine
stays closed until the coolant temperature at the ENGINE reaches 87C (189F)
degrees. It is the responsibility of the Radiator to keep the coolant temperature
from running too high. However, if the temperature is too high it is not
necessarily the radiator.
A poor radiator cap won't last as long
or stay properly calibrated, and either open at too low or two high a pressure.
Make sure your radiator cap is the proper one for your cooling system. Higher
pressure implies a higher boiling point, which means more efficient cooling. A
new radiator cap is usually all that is required for this (but don’t over
pressurize your radiator cores and wreck the whole system).
Most Radiators' cooling system
failures develop from poor radiator maintenance. Many radiator problems can be
prevented with regular maintenance and periodic professional inspections of you
car radiator and cooling system. The most common radiator problems are: leaky
fittings or seams, fin deterioration and bond failure, electrolysis, cracked
tank, and fan damage.
