Your vehicle’s radiator is the most critical part of your engine’s cooling system. This system works to ensure your engine maintains a safe temperature while in operation. While your engine is running, a variety of moving parts generates a great deal of friction. This friction, along with fuel being burned, means excess heat.
When there’s a problem within the cooling system and it can’t properly control the heat, you can end up on the side of the road with steam pouring out of your overheated engine. Even worse, engine components can melt or meld together and lead to total engine failure. To avoid this, it is important to include your cooling system in your vehicle’s preventative maintenance routine, specifically your radiator.
By taking the initiative ahead of time to keep the radiator properly maintained, you can be confident that it will always be properly functioning and avoid more money and headaches in the future.
What Does the Radiator Do?
It’s safe to say that your cooling system is the main thing that prevents total engine failure. Your radiator is the central component that makes this happen.
The radiator is a large square with coils located at the front of the engine compartment directly behind your vehicle’s grill. Within the radiator is the engine’s coolant, also known as antifreeze. These two terms are often used interchangeably but refer to the same thing. The coolant mixture is a combination of 50 percent coolant and 50 percent water. This fluid prevents the water from boiling at temperatures up to 275 degrees Fahrenheit and freezing at temperatures as low as 30 degrees Fahrenheit.
The radiator itself does not contain any electronic parts but it is regulated by a thermostat near the engine that gauges the current engine temperature. When the engine starts to get too hot, the thermostat allows the radiator to push coolant through the engine.
As the coolant cycles through the engine, it absorbs the excess heat and travels from the engine, through the upper radiator hose, and back into the radiator. The large surface area of the radiator helps the coolant lower in temperature as it runs through the radiator’s coils. The cool air flowing in through the front grill also helps to cool the liquid as well. Once the coolant’s temperature has been lowered to the proper temperature, it travels through the lower hose of the radiator, back to the engine, and the cycle is repeated during the entire time the engine is running.
How To Extend The Life Of Your Radiator
Radiators used to be made entirely of metal and they regularly outlasted the life of the vehicle. Now, in most modern vehicles, the radiator is made mostly of plastic.
In today’s vehicles, a properly maintained radiator will usually last between 8 and 10 years. There are a couple of things you can do to help your radiator last as long as possible:
Proper Levels Of Coolant
The first thing to do is to keep an eye on your vehicle’s coolant level. The engine should always have the proper level of coolant in it before you drive. Coolant can escape when the radiator overheats or through leaks in the cooling system. If the level drops too low, the liquid will overheat and boil over, causing damage to the radiator and the engine itself. If it is during the hot Arizona months or you are about to drive on a long trip, it is even more important to maintain the proper level of coolant. Both of these scenarios make your vehicle more prone to overheating.
If you notice the coolant level is lower than it should be, it is easy to add more. First, make sure the engine is completely cool. Many modern cars have a separate coolant reservoir you can pour the coolant into using a funnel. If not, the liquid will be poured directly into the top of the radiator after removing the cap. Make sure to never open the radiator cap if the engine is still hot. Keep in mind that the liquid you want to be adding to the system is half water and half coolant. You can find a pre-mixed coolant at an auto parts store or you can mix it yourself.
Your vehicle’s owner’s manual will have specific instructions for how to top off the coolant in your vehicle.
