Types of Plastic Heater Cores

Car plastic heater cores come in a variety of types to help heat the air inside the car. Below are the types:

• Aluminum heater core

  These are the most common types of heater cores available. They are mainly used because they are lightweight and very resistant to corrosion. Also, aluminum heater cores are known for their excellent heating efficiency. They heat the air inside the car very fast. Because aluminum is a soft metal, these heater cores are very easy to manufacture into complex shapes. This allows them to be designed into any shape and size that will offer the desired heating performance.

• Brass and Copper Heater Core

  Brass and copper heater cores have been used in the past, especially in older car models. Nowadays, they are mainly used in cars that have very high heating demands. For example, they can be found in heavy trucks and some industrial vehicles. This is because brass and copper are very good at withstanding high temperatures and corrosion. They are also very durable and can last for many years with minimal wear and tear. This makes them suitable for applications where the heater core is frequently used for extended periods. Like aluminum, copper is also a good heat conductor. Therefore, these heater cores can produce a lot of heat energy within a short time.

• Plastic heater core

  These heater cores are mainly used in modern cars. They are mainly preferred because they are lightweight and corrosion resistant. Plastic heater cores are also less prone to rust, which is a common problem in metallic heater cores. They are mainly used in areas where corrosion is a major concern, such as coastal regions. Additionally, plastic heater cores are very affordable. They can also be manufactured into complex shapes and designs, allowing for customization according to the needs of various car models.

• Variable heater core

  These are advanced types of heater cores that are mainly used in modern cars. They use a lot of technology and can automatically adjust to the set temperature inside the car. This allows for precise temperature control. Also, variable heater cores improve the overall energy efficiency of the heating system in a car. They reduce the need to crank up the car's heater to the maximum.

Specification and maintenance of plastic heater cores

Before buying a car heater core, one should know its specifications. Here is the list.

• Type

  The first specification of a car heater core is its type. The type is determined by the construction and design of the core. Is it a plastic heater core? If so, it is made from plastic and aluminum like the conventional ones. It is lighter and resistant to corrosion. The other type is a brass core. It is more durable than the other types but heavier.

• Size

  Heater cores come in different sizes. The size is measured by the dimensions of the core. This includes the length, width, and height. A larger core has a higher heat transfer rate than a smaller one. Therefore, the size of a plastic heater core is determined by the vehicle's size and need for heating.

• Flow direction

  The flow direction of the coolant inside the heater core is also a specification. It can be either parallel or series. In a plastic parallel heater core, the coolant flows through multiple paths that are parallel to each other. On the other hand, in a series core, the coolant flows through a single path through multiple elements.

• Fin design

  The fins of the core are responsible for heat transfer. They are designed in different ways depending on the model of the heater core. The fins can have a louvered design, plain or wavy.

• Connection size

  This is the size of the ports used to connect the core to the cooling system. The connection size is determined by the diameter of the inlet and outlet pipes. It is measured in millimeters or inches.

Once the specifications of a heater core are decided, it is important to maintain it. Here are some maintenance tips for a plastic heater core.

• Regular flushing

  To maintain a heater core, it should be flushed regularly. This helps remove any debris and build-up inside the core. This can be done by disconnecting the hoses from the core and then running water through it.

• Coolant replacement

  Another tip to maintain a car heater core is by replacing the coolant. This is because old coolants have contaminants that can clog the core. The coolant should be changed regularly according to the manufacturer's recommendations.

• Check the hoses

  The hoses connecting the core to the cooling system should also be inspected. This is because damaged or worn-out hoses can affect the performance of the core. Therefore, the hoses should be checked regularly for signs of wear, cracks, or leaks.

• Prevent freezing

  In cold areas, the heater core should be protected from freezing like other car parts. This can be done by using a proper antifreeze mixture in the cooling system. The antifreeze should be maintained at the recommended level to prevent damage to the core from extreme cold.

• Address leaks

  Any leaks in the core should be addressed immediately. This is because leaks can cause a drop in temperature and affect the performance of the core. In case of a leak, the damaged core should be replaced.

How to Choose Plastic Heater Cores

When sourcing these cores for resale, here are some important factors to consider:

• Vehicle Compatibility

  Ensure the plastic heater core is compatible with the target vehicle's make, model, and year. This reduces the chances of plastic heater core replacement failure. For example, the Ford F-150 and Dodge Ram 1500 are popular vehicles that use metal heater cores.

• Core Size and Dimensions

  Measure the old heater core's inlet/outlet pipes, core width, height, and thickness. The new core should match these specs for a proper fit. A core that is too big or small will not work effectively.

• Cooling Capacity

  Determine the required cooling capacity based on the vehicle's engine size and climate conditions. The core should be sized to heat the cabin adequately. Larger cores have more surface area to transfer heat, so they are better for colder climates.

• Quality and Standards

  Look for cores that meet industry quality standards. Check for certifications like ISO9001, IATF16949, ROHS, etc. This ensures the core was manufactured with quality control. Also, read reviews to gauge the reliability of the heater core.

• Ease of Installation

  Consider how easy it will be to install the plastic heater core replacement. Cores with straightforward instructions and video demos are better. Also, think about the tools and skills required. A core that is difficult to install may lead to customer complaints.

• Warranty and Support

  Select a core with a good warranty period. This protects the investment in case of defects. Also, choose a supplier who offers technical support in case of any issues.

• Price and Value

  Finally, compare prices from different suppliers. But remember to also consider the core's quality, features, and performance. The most expensive core may not be the best value.
