Jeep TJ Radiator Upgrade Benefits

There are a number of benefits in upgrading the radiator of Jeep Wrangler TJ, even if it’s not quite asking for an upgrade. Aftermarket radiators, especially those for older models, are much more efficient at cooling.

Here are the main benefits.

More Rows, Better Cooling

Legacy radiators didn’t have as many rows in the radiator as today’s models do. The greater the number of rows and fins, the better the heat dissipation. So a TJ radiator upgrade with more rows than the factory-installed one is definitely going to be an improvement.

Aluminum Construction

You can improve the cooling rate considerably with a Jeep TJ aluminum radiator. Aluminum is a material that dissipates heat much better than some of the other common metals and alloys. For this reason, most modern radiators are fully constructed with industry-grade aluminum.

This can benefit you and save you from any potential repairs due to overheating. An overheating radiator doesn’t just cause the car to break down in the middle of the road but may also lead to other issues under the hood.

Lightweight

The factory radiator in your Jeep would likely be made of brass, which is much heavier than aluminum. A lightweight radiator can help improve the performance of the car. It will give a boost to the horsepower, converting those few extra pounds into speed.

Dual-Pass Design

The new performance radiator for Jeep TJ would have a dual-pass design, in that the tubes go from one side to the other and then turn back and so on. So basically, they exit on the same side as they started.

This design structure also affects the cooling rate, resulting in that sweet spot where you don’t want it too hot or too cold.
