All About Car Radiators |

Your car radiator is the primary cooling mechanism for your engine. Light and strong, aluminum is great for making radiators. It is the material of choice for most of today's radiators. Light and intelligently designed, aluminum radiators are standard on many of today's new cars and trucks.
A small leak on your radiator can be indicating a larger problem. 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 moves through the radiator does not change the amount of heat that is dissipated by the cooling cores. The amount of cooling will not 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 top-quality 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 are overheating in traffic to help push more air across the cooling cores and more coolant through the engine.
All water-cooled radiators have an automatically controlled electric fan 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 will not 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 means 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 arise 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.
