Before we focus on aluminum radiators, it’s important to understand how you’re radiator works. Your factory engine before any modifications produces high heat. To prevent your engine from overheating, your car pumps coolant through the engine. This fluid receives the heat and carries it away from the engine block. The coolant takes the heat generated from your engine and moves it to your radiator. The radiator blows air across the liquid, cooling it down, and exchanging heat with the air outside your car. The coolant is passed through thin metal fins that allow the heat to flow to the air outside your car. To sum it up, the main purpose of the radiator is to cool the coolant, which then cools your engine.
When browsing for a new radiator, you will come to find they can be manufactured from several different material types. We will focus specifically on Aluminum Radiators in this article.
Aluminum radiators are the common choice for many street and track performance applications. Performance-minded customers opt for a radiator replacement for one or more of the following reasons: they want lighter weight, they’re upgrading the cooling system for improved efficiency or they want to enhance their under hood appearance.
So how does an aluminum radiator achieve all of these things?
First and foremost, they cool better than a copper brass radiator. For example, an aluminum radiator with 2 rows of 1″ tubes is equivalent to a copper brass radiator with 5 rows of 1/2″ tubes. Aluminum radiators are often offered in multi-row options. You may have heard the terms “2 row radiator” or 3 row radiator” used in the industry. This simply refers to the amount of rows in the core of your radiator. More rows mean more coolant can flow through the radiator, thus keeping your engine cooler.
Factory radiators are manufactured in most cases as a mix of aluminum and plastic. Aluminum radiators are manufactured from just aluminum. This greatly reduces the changes of your radiator leaking as the plastic tanks found on OEM radiators often crack over time.
In most cases an aluminum radiator will also be a lightweight option. This makes it a great upgrade for any vehicles with copper radiators.
