6-Cylinder Radiator Buying Guide

A radiator is an extremely important component of any car, responsible for keeping a car's engine cool, thus protecting it from overheating and malfunctioning. For various reasons, a radiator can malfunction and may need to be replaced. When this happens, car owners often find it difficult to choose the right radiator for their cars as almost all radiators look the same. However, buying a new radiator can be a simple task if car owners know enough important information about car radiators to make an informed choice.

People who drive 6-cylinder engine cars should get radiators compatible with their cars, also referred to as 6-cylinder radiators. Six-cylinder engines are usually considered big engines, and require significant cooling power to keep them functioning well. Therefore, users should know how to buy the right 6-cylinder radiators for their cars.

6-Cylinder Radiator Parts and Functions

Six-cylinder radiators are named so because they are designed for 6-cylinder engine cars. These radiators are big enough and have sufficient cooling abilities to cool these engines. Knowing the basic components of a radiator, as well as their functions, may help buyers choose the right radiators for their cars.

Radiator Part

Details

Function

Radiator fin

Is cooled down by the wind, which in turn cools down any radiator fluid

Dissipates heat from the coolant to the environment

Radiator cap

Covers the top of the radiator

Prevents air from entering the coolant and the coolant from spilling out

Turbulator

A set of fins attached to the tubes in a radiator

Increases the turbulence of the flowing coolant and amount of heat dissipated from the coolant

Tubes

Also seen in the radiator core; tubes should be strong and able to efficiently transfer radiator fluid

Transport the fluid between the radiator and engine

Fan

Includes electric, flex, manual fixed, and thermal sensing clutch fans

Increases the amount of air passing through the radiator core

When shopping for 6-cylinder and other radiators, buyers should make sure that all parts are in good condition. They should not be bent, deformed, or damaged, because their functionality depends heavily on their structural condition. Some parts of a radiator like the fan, as well as tubes and hoses, may not always come with a radiator, so one may need to buy those parts separately.

Crossflow or Downflow Radiator?

Two main styles of 6-cylinder radiators are the crossflow and downflow radiators. Although these two designs serve the same purpose, they do it very differently. They both have distinct features, so buyers should easily be able to differentiate the two.

A crossflow radiator has a vertical tank on each side with the cooling fins and tubes in the centre core. The coolant flows horizontally across the radiator core, and usually moves slower than in a downflow radiator. A downflow radiator has its tanks positioned horizontally on its top and bottom. The coolant enters the top of the radiator and flows vertically through the radiator. Compared to a crossflow radiator, which relies on a water pump for the coolant flow, a downflow radiator relies more on gravity, causing the coolant to flow faster.

Since the coolants in crossflow radiators move slower than in downflow radiators, crossflow radiators are more efficient at dissipating heat and are often used in high-output engines. They also look sleeker and wider than tall downflow radiators. However, downflow radiators, with their tall front grilles, look much better on classic cars than crossflow radiators.

Radiator Material

The two main materials used to make radiators are copper-brass and aluminium-plastic. Copper-brass radiators were standard on classic and vintage cars, though some cars produced up to the 1980s still had these radiators. These radiators also conduct heat very well and look great on classic cars. However, they are relatively weak compared to aluminium ones, and copper-brass tubes have to be kept small to prevent ballooning and rupturing under pressure. However, this means that less coolant can flow through the tubes, and the cooling ability is reduced.

Since aluminium is stronger than copper-brass, aluminium tubes can be bigger than copper-brass ones. This allows the tubes to carry more coolant and increase the radiator's cooling ability. Aluminium and plastic are also much lighter than copper-brass, making aluminium-plastic radiators the main choice in modern cars, especially high performance ones. However, copper-brass radiators have a vintage and classic look, and can work well for buyers restoring their vintage cars.

Radiator Row Number and Tube Size

Six-cylinder radiators can have a number of rows containing fins and tubes. Originally, when copper-brass radiators were common, they used to have many rows of small tubes. However, after aluminium radiators were developed, the size of the tubes could be increased as they were stronger than copper-brass tubes. This leads to most modern radiators having only a few rows, in general two or three, compared to the five or even more rows earlier radiators had.

An aluminium radiator with two rows and larger tubes has the same efficiency and cooling capacity as a copper-brass radiator with more rows and smaller tubes. Also, with fewer rows, more air can pass through the core, thus further cooling the radiator. Although fewer rows on a radiator means that it can function more efficiently, for a copper-brass radiator, more rows is better.

What to Consider when Buying a 6-Cylinder Radiator

Besides choosing the style, material, and number of rows on a radiator, there are other things buyers should look at. First, it is important to check the size of the car's engine compartment and find a radiator of the right size. Second, inspecting the condition of a radiator is always a good idea before purchase.

Radiator Fit

While a bigger radiator usually provides better cooling for the engine, the radiator must also be able to fit in the engine bay. Also, buyers should consider the transmission of their cars. Automatic transmission cars may need to have transmission coolers as well.

Radiator Condition

Besides having all the necessary parts intact, a radiator should not have any blockages in its tubes. Otherwise, the coolant cannot flow smoothly through the radiator. Lastly, buyers should consider the cost of their radiators. It is wise to set a budget and look for suitable 6-cylinder radiators within that budget to avoid overspending.

How to Buy a 6-Cylinder Radiator on eBay

To look for a 6-cylinder radiator on eBay, type your preferred keywords into eBay's search bar, and let eBay do the work. Then, you can browse through the available radiators and pick the one you like. You can search for '6-cylinder radiators' or use other keywords. Besides using eBay's search feature, you can also visit the eBay Deals page and check if there are any good deals on 6-cylinder radiators.

When checking out the radiators, you should read their descriptions, prices, and shipping fees. Also, if you need a radiator fan, search for radiators with fans included. Lastly, before purchasing a 6-cylinder radiator, be sure of its condition and compatibility with your car.

Conclusion

When buying radiators for 6-cylinder engine cars, it is important for buyers to make sure the radiators are compatible with their cars. After all, radiators cool down engines, allowing them to function normally. When shopping for 6-cylinder radiators, it is useful to know the parts in a radiator, and make sure that they are in good condition.

Things to look at when choosing the right radiator are its style, material, number of rows, and tube size. Most modern cars use crossflow radiators made of aluminium and plastic since they are lightweight and efficient at cooling down engines. But downflow radiators and copper-brass ones can enhance the look of vintage cars. No matter what kind of radiator buyers want, they are likely to find a suitable one on eBay.
