What is the Radiator

auto-repair-9To help keep your vehicle well maintained, make sure to bring the vehicle in on a regular basis. Part of inspecting the vehicle will deal with the radiator. This is important because the radiator is used for cooling the engine of your vehicle. This helps to avoid problems such as overheating. As a fluid called coolant passes through the engine block, it cools the engine down, losing the heat into the atmosphere by a fan. If the vehicle starts to overheat, it could be an indication of a radiator issue. Make sure to schedule an appointment as soon as possible so the radiator can be repaired. This helps to provide a reliable and pleasant drive.

Where the Radiator is Located

The radiator of your vehicle is typically located toward the front of the vehicle next to the engine. The job of the radiator is to keep the engine cool and prevent it from becoming too hot. Radiators consist of many small tubes with cooling fins that allow the coolant to be cooled down and then returned to the engine in a constant cycle. Always check the coolant level to ensure it is topped off. This can help the efficiency of the radiator, without it overheating.

How the Radiator Works for the Vehicle

Radiators are made of aluminum with thin tubes connected to the component. The coolant flows from the inlet to the outlet through these small tubes. A tabulator, or type of fin, is inserted into the radiator, which helps to increase the turbulence of the fluid flowing though the tubes. Only fluid that actually touches the tubes will be cooled directly. The more turbulence inside the tube, the more all of the fluids mix together. This keeps the temperature of the fluid that touches the tubes hotter and more heat can be extracted. When the fluid in the radiator heats up, the radiator cap is the only place where the pressure of the heat can escape. Once the temperature of the coolant reaches a certain degree, the cap will start to open allowing heat to escape and the fluid to flow throughout the radiator.

Signs of a Poor Radiator

One way to recognize if the radiator is failing is to pay attention to the temperature of your vehicle. If you notice that the temperature does not remain stable, then this could indicate that your radiator might need an inspection. If your vehicle overheats, a faulty radiator could be the cause. Also, if you notice leaks under the part of the vehicle where the radiator is housed, this could be a sign that the water pump is in danger. Coolant leaks are the most common form of diagnosing a bad radiator. Performing a routine maintenance check is beneficial to your vehicle. Part of this maintenance entails regularly checking your coolant fluid. This helps to ensure that there are not any leaks and allows you to catch problems more quickly. If you notice grinding sounds this could signify a coolant leak as well. Ignoring this sign can cause the bearings to break and could release the radiator from the vehicle. By inspecting the vehicle, you can help keep it running as long as possible without a costly repair bill.
