Features to Look for Before Buying 

So your car’s radiator gave up on you? Bummer. Now, you are frantically looking for a replacement but have no idea what features to look for before buying to ensure value for the money you are bound to be spending.

Worry no more because here’s a list of features to watch out for when you are in the market for a new replacement radiator.


Longevity and durability are highly important to get maximum value for your money. Nobody wants to buy a new radiator every month because they settled for one of the scraps in the market that lasts shorter than a candle’s wick, right?

The most important thing to consider to ensure longevity and durability is, of course, the material that the product is made of. Up to the 1980s, radiator cores were often made of copper or brass.

However, for prolonged functionality, you should opt for one made of aluminum. Not only does this material ensure longevity, but it also reduces weight and makes the unit relatively less expensive than radiators made of copper or brass.

Easy Installation

Unless you are a licensed mechanic, an important feature to look for is that of easy installation. Simply stated, it is best to stick to brands and units which would not require you to hire someone to install it or would require extreme modifications to ensure a fit.

Look for a radiator that comes with an easy-to-follow guide or manual for easy installation or one that guarantees to fit. That way, you get to enjoy the advantages of a good radiator without the stress and the added cost.


There’s really no point in getting a radiator if you cannot be ensured that it is efficient in function and performance. It is completely natural, then, that the most important consideration when looking for a radiator is its efficiency to perform this task.

To make sure that the radiator you are eyeing is efficient in this regard, it is important to consider how it is engineered, designed, and finally manufactured.

Look for a product that has undergone rigorous in-house testing to determine whether or not it can withstand pressure build-up and release during tens and thousands of cycles.

Equally important is if the unit has been subjected to extreme hot and cold temperatures, and it remains intact and stable to ensure a leak-free and durable design.

With that in mind, let’s hit the reviews to find the perfect radiator for you and your vehicle.
