• Industrial machinery
• Trucks and buses
• RVs and campers
• Construction equipment

Aluminum Radiators have several advantages over traditional brass and copper radiators. These advantages include:

• Weight savings: Aluminum is much lighter than brass or copper, so Aluminum Radiators  can save significant weight. This is especially important in racing applications where every pound counts.
• Better heat transfer: Aluminum is a better conductor of heat than brass or copper, so it more efficiently transfers heat away from the engine.
• Corrosion resistance: Aluminum is much more resistant to corrosion than brass or copper. This means that aluminum radiators will last longer and require less maintenance [1].

How to choose Aluminum Radiators?

Types

There are several types of Aluminum Radiators available on the market today. The most common type is the cross-flow radiator, which is designed to fit in between your engine and transmission. This type of radiator is the most efficient at cooling your engine, as it allows coolant to flow evenly across all cylinders.

The next most popular type of Aluminum Radiator is the down-flow radiator.

However, they are still a good choice for many applications.

Finally, there are oil cooler kits available that can be used to cool your transmission fluid or motor oil. These kits usually come with their radiator, and they are a great choice for those who want to keep their transmission fluid or motor oil cool.

Radiator Cap

The radiator cap is an important part of your cooling system, and it is responsible for maintaining the correct pressure in your radiator. It is important to choose a radiator cap that is rated for the correct pressure for your application.

Pressure ratings are usually expressed in pounds per square inch (PSI). A higher PSI rating means that the cap can withstand more pressure, and it will be able to keep your coolant from boiling over.

It is also important to choose a radiator cap that has a good seal. A good seal will prevent coolant from leaking out of your radiator, and it will also help to keep dirt and debris out of your cooling system.

Structure

Aluminum Radiators are made up of a series of tubes that are connected to each other by fins. The tubes are responsible for carrying the coolant to and from the engine, while the fins help to dissipate heat.

The number of tubes and fins will vary depending on the type of radiator you choose. Cross-flow radiators typically have more tubes than down-flow radiators, and they also have more fins.

The number of rows will also vary depending on the type of radiator you choose. Down-flow radiators usually have two or three rows, while cross-flow radiators typically have four or five rows.

Valves

Aluminum Radiators are available with either manual or automatic valves. Manual valves are less expensive, but they require you to manually open and close them. Automatic valves are more expensive, but they will automatically open and close when the engine is turned on and off.

If you choose a radiator with an automatic valve, it is important to choose one that is rated for the correct pressure. Otherwise, you may find that your coolant boils over when the engine is turned off.

Core Size

The core size of your Aluminum Radiator will determine how much heat it can dissipate. The larger the core, the more heat it can dissipate.

The size of your radiator will also determine the type of fan you will need to cool it. The larger the radiator, the bigger the fan you will need. It is important to choose a fan that is rated for the correct CFM (cubic feet per minute) rating. Otherwise, you may find that your engine overheats when the fan is not running at full speed. You can also choose an electric fan, which will be more expensive but will not require a separate power source.

Electric fans are available in both pusher and puller configurations. Pusher fans mount in front of the radiator and push air through it, while puller fans mount behind

However, a larger core also means that the radiator will be heavier and more difficult to install. If you are unsure about which size to choose, it is best to consult with a professional.

Materials

Aluminum Radiators are available in both aluminum and copper/brass construction. Aluminum Radiators are less expensive, but they are not as durable as copper/brass radiators. Copper/brass radiators are more expensive, but they will last longer and provide better cooling performance.

If you choose an Aluminum Radiator, it is important to choose one that is made from high-quality materials. Otherwise, you may find that your radiator leaks or breaks down after a few years of use.

It is also important to choose a radiator that has been powder coated or anodized. This will help to prevent corrosion and extend the life of your radiator.

Powder coating is a process where the powder is applied to the surface of the aluminum and then baked on. Anodizing is a process where the aluminum is dipped in an acidic solution and then exposed to an electrical current. This process creates a thin layer of oxide on the surface of the aluminum, which helps to prevent corrosion.

Aluminum Radiators are available in both natural finish and polished finishes. Natural finish radiators will have a dull appearance, while polished finish radiators will have a shiny appearance.

Polished finish radiators are more expensive than natural finish radiators, but they are easier to keep clean. If you choose a polished radiator, it is important to choose one that has been powder coated or anodized. Otherwise, you may find that your radiator corrodes over time.

Row Quantity & Tube Size

The number of rows and the size of the tubes in your radiator will determine how much heat it can dissipate. The more rows and the larger the tubes, the more heat it can dissipate. The number of rows can on average be between two and seven.

The average tube size is between 19 mm and 25 mm. If you choose a radiator with a large number of rows and small tubes, it will be more efficient at cooling your engine. However, it will also be more expensive and more difficult to install.

If you choose a radiator with a small number of rows and large tubes, it will be less efficient at cooling your engine. However, it will be less expensive and easier to install.

It is important to note that the number of rows does not necessarily have to match the number of cylinders in your engine. It is often recommended that you choose a radiator with fewer rows than there are cylinders in your engine. This will help to prevent coolant from being forced through the radiator too quickly and will improve cooling efficiency.

The size of the tubes in your radiator will also determine how much heat it can dissipate. The larger the tubes, the more heat they can dissipate. However, large tubes are more difficult to install and are more expensive.

Aluminum radiators are available in both standard and high-performance configurations. Standard radiators are less expensive but do not provide as much cooling capacity as high-performance radiators. High-performance radiators are more expensive but provide better cooling performance [2].

Selection of coolant

The type of coolant you use in your radiator will also affect its performance. The most common type of coolant is ethylene glycol. Ethylene glycol is a good choice for most applications because it has a low freezing point and a high boiling point. However, ethylene glycol is toxic and should not be used if there is any chance that it might come into contact with children or pets. If you choose to use ethylene glycol, it is important to use only the amount recommended by the manufacturer.

Propylene glycol is another type of coolant that can be used in radiators. Propylene glycol does not have as high of a boiling point as ethylene glycol, but it is non-toxic and can be used in applications where there is a chance of contact with children or pets.

Marking

When choosing an Aluminum Radiator, it is important to check the markings on the radiator. The markings should include the manufacturer’s name, the model number, and the date of manufacture. The date of manufacture is important because it will tell you how old the radiator is. Another marking that you should look for is the ASME code. The ASME code is a symbol that indicates that the radiator has been certified by the American Society of Mechanical Engineers.

Pressure rating

The pressure rating of an Aluminum Radiator is important because it will tell you how much pressure the radiator can withstand without leaking. The pressure rating is usually expressed in pounds per square inch (psi). The higher the pressure rating, the more expensive the radiator will be. However, a higher pressure rating will also mean that the radiator is less likely to leak.

Some radiators are made with thicker walls and more rows than others. These radiators are generally more expensive but offer better cooling performance. If you are looking for a high-performance radiator, it is worth paying extra for one that has been designed specifically for high-performance applications.

How to Install and Replace a Radiator?
