Ways to Notice an Issue with the Radiator

Proper maintenance of your vehicle is important. The first sign that there is an issue with the cooling system in your vehicle will often come from the temperature gauge. If your vehicle has been running consistently warmer or has recently begun having issues with overheating, there is likely an issue with the cooling system. The temperature gauge in your vehicle should have an acceptable operating range. Even if your vehicle is not overheating but has been running at the higher end of the operating range, there may be an issue. If your vehicle is running with the temperature gauge in the red, it is overheating. Pull over and shut off the vehicle. Issues with the cooling system can also cause the engine to run cold. In that case, the temperature gauge will remain in the blue.   Another early indicator of a problem with your cooling system may be the check engine light on your dashboard. Your check engine light comes on when one of the sensors in your car sends a message to it. Many vehicles have dash board lights that will notify you of low coolant levels or extreme engine temperatures as well.   Leaks are a common issue in coolant systems. If you spot a puddle beneath your vehicle, there’s a chance that it may be the result of a coolant leak. Oil is often brown or black, water from the air conditioner will be clear, and coolant will likely be green, pink or orange. A leak in your coolant system can cause it to fail to maintain proper temperature in the engine. If you suspect that your vehicle has a coolant leak, pop the hood when the engine is cool and look at your coolant reservoir. The reservoir will have lines indicating the minimum and maximum coolant capacity for your vehicle. Take note of the level the coolant reaches on the reservoir, then check again in a few days. If it has gone down, the coolant is either leaking or being burned. If you notice an issue with the radiator or your vehicle overheating, make sure to contact us so we can inspect it for you.

Do not forget about the Cooling System of Your Vehicle

When inspecting your vehicle, it is important to check all the parts and components for it. To have the best maintenance possible, it is recommended that you bring the vehicle in so we can inspect it thoroughly. Part of the inspection may include the cooling system of the vehicle. The engine creates a lot of heat while you are driving. It is important that this heat is removed immediately. If it is not than there can be problems in oil degradation and possible overheating of your vehicle. This is why it is important that you are not only maintaining your cooling system, but that you understand the different components which have a lot to do with the cooling of your engine. This will help in making sure that you are able to maintain a cool engine at all times. Among the things that you will need to know about includes the radiator. The water pump is an integral part that you should know about. Additionally, you should know about the hoses and connections which help to maintain the temperature of your engine. This will help in making sure that you will be able to understand whenever there is a problem with the cooling system. You will also be able to make sure that you are keeping an eye out for these different elements in order to maintain a cool engine. The Importance of the Water Pump The water pump is one of the most important parts of your cooling system. It is responsible for moving the coolant throughout your engine. Without this, there is no way that the engine will be able to maintain its temperature. These parts are fairly durable and seldom, if ever, need replacing. This is something to keep in mind though. If there is a problem in which your engine is overheating, it could be very well that the pump has malfunctioned in some way. This will cause you problems in which you will have to pay more to repair. Issues with the Radiator The radiator is where the coolant goes after it has been through the engine. This is a large grate which allows air to move through it. There is a fan which blows against the radiator along with the air flow that you will be able to get from driving your car. As air moves over the grates, it removes the heat from the coolant and whisks it away. If there is a problem with your radiator, it can cause the coolant to not be able to flow through it. Of course, these problems could also cause problems in which air will not be able to flow through the radiator to cool the coolant. Hoses and Connections should be inspected There are two hoses which are connected to the radiator which are responsible for bring in the coolant and drawing it out. The upper hose and the lower hose are integral to the operation of the cooling system. Without them, the flow of coolant will cease. This is why if there is a problem with one of the hoses, it will need to be replaced as fast as possible. There is also a line which will allow hot air to escape from the radiator and to the exhaust. This will allow the hot air a place that it can go to.

When to Know the Radiator Should Be Replaced

Keeping your vehicle well maintained is important for the overall condition of it. This will also help you to save time, money, and stress in the long run. Besides having the vehicle inspected by us, you can also inspect some parts between visits. It is always recommended that if you notice anything out of the norm, you contact us and bring the vehicle in as soon as you can. One item to check is the radiator. The radiator is an important part of the engine. The engine will get hot while it is operating. This is easy to understand since it is a combustion engine that relies on burning gasoline in order to maintain the power it needs. The engine relies on radiators to get the help needed to maintain power and efficiency. Whenever the radiator is not working properly, it is important that it is either repaired or replaced. It is important to know when you will need to have this part of your engine inspected to decide which you will need. There are a few tips that can help you determine that the radiator is not operating correctly. The first thing is you will get less engine efficiency because the engine will be running hot. You will also notice that it is more of a strain to get any performance out of your vehicle. Of course, you might also notice smoke or steam coming from your engine. This is something that you will need to take into consideration so that you will be able to make sure that your fuel injection is able to provide the power that you deserve as you are driving down the road. Be Aware of the Temperature Gauge The temperature of your engine will cause you to face certain problems like blowing gaskets or even cracking your engine block. Temperatures which run too high will create all kinds of problems which will cost you a lot of money. The ideal situation will include stopping the car and getting it towed as soon as you notice that the temperature gauge is getting into the red. This will help to prevent serious engine damage caused by a faulty radiator. A Decrease in Vehicle Performance Another thing to watch for is a decrease in performance. This is caused by many of the different parts of the engine like the cylinders not being able to operate correctly because of the swelling which happens in the metal. The engine will have to work twice as hard to get the same amount of performance. You might even notice problems that might feel like your vehicle is out of alignment. The decrease in performance is because the coolant has no way to cool down properly because the radiator is not operating correctly. Instead, the coolant continues to heat up as it is cycled through the engine. Noticing Smoke Coming from the Engine Another thing to notice is smoke coming from the engine. This will generally happen whenever the vehicle is completely seized up. If you are lucky, it will happen as the engine starts to get too hot or the coolant starts to fail. It is important to shut down the engine as soon as you see any smoke. This will help in making sure that you will be able to get a tow truck to your vehicle before you do any more damage to the engine. We can then inspect the radiator for you to ensure it is in the best condition.

What is a Radiator?

A radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan.  In most cars, there is one radiator, which is located at the front of the vehicle.  Some high performance autos, such as the Bugatti Veyron, have 12 radiators to cool down its larger engine.  The famous design of the Rolls Royce’s radiator grille was inspired by the Parthenon, a Greek temple located in Athens, Greece.  The first automobile radiator was designed and invented by Karl Benz and Wilhelm Maybach for the Mercedes 35HP engine and was known as a “Honeycomb radiator” due to its honeycomb-like design. What does a Radiator Do? To cool down the engine, a coolant is passed through the engine block, where it absorbs heat from the engine. The hot coolant is then fed into the inlet tank of the radiator and distributed across the radiator core. As the coolant circulates through the radiator tubes on its way to the opposite tank, it cools again. The tubes transfer heat from the coolant to fins that are lodged between each row of tubes. The fins then release the heat to the ambient air. Fins are used to greatly increase the contact surface of the tubes to the air, thus increasing the exchange efficiency.  The cold coolant is then fed back to the engine, and the cycle repeats.  For each vehicle manufacturer, it takes more than 8000 miles of material strip for the production of radiators annually. Brass and copper were the base materials of the radiator, but due to chemical reactions the materials had to be replaced by plastics and aluminum.  These radiators are made by brazing thin aluminum fins into flattened aluminum tubes.  Radiators often have one or more fans that blow air through the radiator. To save fan power consumption in vehicles, radiators are often behind the grill at the front end of a vehicle. Just driving the car can supply a portion or all of the necessary cooling air flow so the fan can remain disengaged. What Coolant does a Radiator Use? This coolant is usually water-based, with the addition of glycols to prevent freezing and other additives to limit corrosion, erosion and cavities. However, the coolant may also be an oil. The first engines used thermo siphons to circulate the coolant.  Today, however, all but the smallest engines use pumps.  Since air has a lower heat capacity and density than liquid coolants, a fairly large volume must be blown through the radiator core to capture the heat from the coolant.  The tubes sometimes have a type of fin inserted into them called a turbulator, which increases the turbulence of the coolant flowing through the tubes. If the coolant flowed very smoothly through the tubes, only the coolant actually touching the tubes would be cooled directly. The amount of heat transferred to the tubes from the coolant running through them depends on the difference in temperature between the tube and the fluid touching it. So if the fluid that is in contact with the tube cools down quickly, less heat will be transferred. By creating turbulence inside the tube, all of the fluid mixes together.  This keeps the temperature of the fluid touching the tubes up so that more heat can be extracted and all of the fluid inside the tube is used effectively.
