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.
Closer Look at Chevrolet Radiator
Essential to your cooling system, your Chevy radiator is located just behind the grille in the front of your engine compartment. In this location, your Chevy radiator is able to enjoy the full benefit of the cooling air that passes through the grille when the vehicle is in motion. However, this necessary placement also leaves your radiator somewhat vulnerable to a variety of road hazards. A front-end accident or collision often ends up in damage to your Chevy radiator, and it can also suffer damage from road debris that is tossed upwards, with rocks being able to strike it with enough force to create small holes, especially if the underside of the Chevy radiator has been weakened by corrosion after years of exposure to often salt laden road splash. Rust can also attack your Chevy radiator from the inside out, with little flakes of rust breaking off inside and collecting in its curves and tiny tubes to form clogs. Thus, having to replace your Chevy radiator once or twice during the life span of your vehicle is not at all unusual. Fortunately, when you drive a Chevy, there is no shortage ' especially when you shop with us ' of affordable replacement parts, and a quick browse through our online catalog will yield a suitable and well-priced replacement for your Chevy radiator.

- Can a radiator for my Chevy cool down my ride without airflow?
It can, but it needs ambient air around the radiator to do so. The ambient air temperature should be below the running temperature of the radiator fluid. Your ambient temperature can end up higher than the air outside when sitting on a stoplight with the hood closed, since the heat generated from your A/C, exhaust, engine and so forth could affect it.
That's why air flow remains important for your radiator; because otherwise, it's nothing more than a hot water reservoir. The tubes get heat transferred to them through coolant, then they transfer the heat to the fins. Meanwhile, air moving through the fins dissipates the hotness from your radiator. Your radiator should be designed in a way that allows effective passage of air.
- How do I avoid getting my Chevrolet radiator clogged?
A clogged radiator can result with it overheating along with the rest of your car. This clogging is usually caused by a dirty radiator filled with debris such as stones from the road, dead insects that somehow ended up under the hood of your car, dirt and dust, or grime.
To counteract this airflow blockage and avoid radiator overheating, you should open the bonnet to check the radiator regularly. There's also the issue of internal clogs. Scan the radiator surface for cold spots with an infrared thermostat from you or your mechanic. Otherwise, check the fluid for suspended contaminants or discoloration.
- How many times should I renew my coolant and why?
Coolant should be renewed every time your radiator is serviced (which, in turn, should be done annually). Checking the status of your coolant, meanwhile, requires a monthly checkup. Topping it up with water is also acceptable.
You should do this religiously because coolant (a mixture of water and antifreeze or ethylene glycol) is kept cool by the radiator as it's pumped around your engine. It keeps water from freezing (hence its name) or boiling. A low coolant level is a common cause of overheating in automobiles.
- Does an aluminum radiator for my Chevy cool better than a copper brass radiator?
Yes. Although copper has better thermal conductivity than aluminum, this benefit has the drawback of having poorer heat dissipation compared to its non-corrosive, lightweight metal counterpart. This is because copper is denser than aluminum, which means it keeps the heat in more since a less dense structure allows for better airflow.
An aluminum radiator with two rows of one-inch tubes has a heat-dissipating capability of a copper brass radiator sporting five rows of half-inch tubes, amazingly enough. Go with aluminum if you want a radiator that easily cools down. Go with copper for better heat conductivity and absorption.
- What about a cast iron Chevrolet radiator. Is it better than an aluminum radiator?
Like with any material, there are pros and cons to using one for another. Cast iron is a radiator material of choice because of its great mass and denseness, which enables it to act as a highly efficient heat store. Long after the central heating has been turned off, it will stay warm. Do you prioritize cool-downs or heat retention more?
If you're looking for instant heat dissipation instead of storage, then the lightweight aluminum radiator is your best bet. However, it can't take too much heat. Aluminum's melting point is at 660 degrees Celsius or 1,220 degrees Fahrenheit. Cast iron, on the other hand, melts at about 1,127-1,204 degrees Celsius or 2,060-2,200 degrees Fahrenheit.
