Beginners foraying into the world of jeeps often wonder whether a radiator is at all necessary for a jeep to run smoothly. Well, you may take your Jeep XJ for a ride without it, but the engine will soon get overheated costing you a few dollars to get a mechanic fix it.

So, you need a good quality radiator to avoid this hassle and keep your jeep motor cool and chill.  The radiator itself is nothing but a cooling system that sends liquid coolants to the various blocks and heads of an engine to absorb the heat generated.

After cooling the engine, the liquid returns to the radiator where it cools down due to the air flowing within, and the process is again repeated. Even when the temperature soars too high and you ride your jeep in hot and arid weather, the radiator keeps the engine from getting too hot.

If you are in the market looking for the best radiator for jeep XJ, you will come across several options, enough to leave you confused. We know you may not have the time for a detailed analysis before pressing on the order button, so we have done the homework for you.

After spending several hours carefully reviewing, analysis, and comparing the products, we have created a list of best radiators to help you choose the perfect one for your Jeep XJ. If you don’t have the time to read this until the end, we suggest the Cold Case 91-01 Jeep Cherokee XJ Radiator that is well-built using pressure tested aluminum and comes with a lifetime manufacturer warranty.

#4. 3 Rows Aluminum Radiator For Jeep Cherokee XJ

This is a 3-rows aluminum radiator designed to perfectly fit a Jeep Cherokee XJ to keep the engine cool and running smoothly in the hottest climates. Those who prefer a 3-rows radiator over a 2-row will benefit from choosing this one made of complete aluminum material.

There are several reasons that make a three-row aluminum radiator better than a two-row version. When there are more rows, it provides more surface area contact with the fin, and this consequently results in much higher heat rejection. Hence, several jeep owners prefer a 3-row radiator over a 2-row to ensure high performance and save in weight too.

Buyers Guide: Things To Consider When Looking For Jeep Radiator

Material

This is perhaps the most important thing to consider as the material determines the overall performance of the radiator. Most good quality radiators are made of aluminum as this is a highly effective material for its lightweight and cooling capacity. Brazed aluminum ensures less distortion and joins stay clean.

Heat dissipation

This will depend on the type of material used for making the radiator. Some are a few three-radiator options that offer higher heat dissipation for more effectiveness. A few brands achieve more heat dissipation via a larger surface area.

Ease of installation

The modern day radiators are easy to install by self, which means that you don’t need to be a mechanic to replace the stock radiator with a new one. However, make sure the product comes with a user manual and essential hardware needed for the installation.

Price Point

Your budget will of course play an important role in determining whether you opt for a high-end radiator or a cheaper alternative. The expensive and high-end radiators will have a superior build quality and include extra features like radiator caps, drain plugs, and TIG-wielded end tanks. In most cases, you get what you pay for.

Related Questions

Why is my Jeep XJ overheating

The early XJ models have a closed style cooling system that causes the fittings and hoses to harden-up and break with time. This also results in tiny leaks in the fittings, further causing the engine to overheat. Sometimes, poor maintenance or inadequate flushing of the cooling system may result in a coked-up system.

What causes a jeep to overheat

Some of the common reasons that cause the cooling system to fail and result in overheating the engine are the bad water pump, malfunctioning fan, stuck thermostat, coolant leaks, head gasket leak, bad radiator cap seal, bubbles or contaminated fluid in the cooling system
