Buyers’ Guide to the Best Radiators

Underneath the hood of modern cars is a complex web of refined machinery, where every cog and screw moves in sync to power these cars forward. This friction and resistance produce heat. The failure to reduce this heat will cause the engine to break down, making the cooling system a crucial aspect. All cars, irrespective of their use for daily errands or in premier competitions, are bound to heat up. A cooling mechanism allows an engine to work at its peak potential by releasing the heat. A key component of the cooling system is the radiator, which uses air to cool the engine.

Things You Should Know Before Purchasing a Radiator

Correct Model

Carefully check the product description: it will specify the car engine and model for which it is designed. Simply put, a radiator designed for a Honda model will not fit a Mustang. If you plan to replace your engine, find a radiator that is compatible.

Coolant Level

Coolant is ideally an equal mix of antifreeze and water. This fluid is pumped around the engine to reduce heat generation with the help of the radiator. The function of antifreeze, as the name suggests, is to keep the water in the radiator from either freezing or boiling in extreme temperatures. Radiators commonly overheat because of insufficient coolant. So, it is important that you check the coolant level annually or when servicing your car. Coolant that has gone bad is generally a shade of rust rather than yellow or green.

Metals Used

Modern engineering has replaced the traditional usage of copper and brass with cost-effective aluminum cores. This change has allowed companies to manufacture lighter and more potent radiators that offer better and faster cooling. Vintage cars may still use older metal compositions if their engines have not been upgraded.

Radiator Cap

A radiator cap is designed to withstand a certain amount of pressure and to release pressure when it exceeds the predetermined limit. Another factor to account for is the per square inch (psi) of
pressure of the cap. The thumb of rule is the higher the psi, the greater the performance. But, a higher psi cap cannot be randomly replaced because cooling systems are designed for specific pressure levels. Excessive pressure could create leaks through the gaskets, damaging the radiator and eventually, causing the engine to breakdown.
