A car's radiator is the heart of its cooling system. Its function is to get rid of the heat from the hot water circulating in the cooling system. The hot water enters the top tank in the radiator, filters down through the core fins of the radiator and cools, and then returns to the engine through the water pump. The engine works better if it does not easily overheat. Frequent engine overheating may affect its life of service, making it wear out early.
Radiator overheating is caused by anything that increases the heat load beyond what the radiator and cooling system can absorb and cool properly. Whether caused by a low coolant level, radiator leaks, malfunctioning radiator fans, a blocked thermostat, or more, overheating is often not a problem if the radiator is maintained and taken care of. If your engine or radiator overheats because of coolant loss, then you should first try and find the source of the coolant leak. You should look at the hoses, the radiator itself, the heater core, water pump, thermostat and the plugs or gaskets. Ultimately, the best way to minimize the risk of overheating is to maintain and service it properly so that it continues to operate at peak performance.
Too often, motorists neglect radiators until something bad happens, which is why radiator problems are perhaps the most common cause of on-road breakdowns. Ideally a radiator and cooling system should be flushed out every six months. This helps avoid blockages in the core and accumulation of rust in the system. If you have a factory-sealed radiator there is no need to do anything unless you detect leaks.
Your Chevy radiator and its parts must be checked regularly to be sure that it is working properly. However, if your radiator has leaks or its parts are worn out, and it doesn't work effectively, it might be the right time to replace them. When replacing a radiator, the measurements of the new and old parts should be close but they do not have to be exact. Sometimes, when people choose from an aluminum radiator to a copper/brass radiator or the other way around, the height, width and thickness varies. Even without a precise measurement match, the cooling capacity will be checked to ensure that it is the same Chevy radiator. A wide array of choices from sites on the net can be of great help in finding your perfect Chevy radiator.
