How do I choose the best radiator for my Jeep TJ? What is the best radiator for Jeep TJ if you own a Jeep Wrangler? Why? Let’s find out.

TJ Jeep’s Iconic Status

Even during the American Motor Company (AMC) days, Jeep models enjoyed near-mythical status as off-road sports utility vehicles.

Jeep’s second generation Wrangler (TJ) – introduced in 1997 as the second generation of this particular line of vehicles – is perhaps the most original Jeep model.

For a decade (1996-2006), Chrysler produced the Jeep Wrangler (TJ). Therefore, all cars on the road today are older models.

Jeep (TJ) vehicles, like all off-road vehicles, have encountered a number of problems. Jeep enthusiasts do not let that dampen their enthusiasm.

What Is The Importance Of Radiator Care?

It is crucial to have a good radiator. The engine and components around the car generate a lot of heat, which can easily damage them.

To keep the engine temperature comfortable, the coolant system circulates water (usually water mixed with antifreeze).

Radiators are where the water/coolant mixture ends up – they dissipate the heat as quickly as possible so it can travel back up the system.

When the radiator fails to do its job, the engine will overheat, resulting in bad things happening.

Off-road vehicles, such as the Jeep Wrangler (TJ), are particularly prone to overheating.

Do you own a Jeep TJ? Radiators Are Definitely Needed

The main reasons are two

  • In general, radiators last 8-10 years, especially if they are made of plastic. Jeep Wrangler (TJ) production ended in 2006.
  • As a result, if you own one, chances are you’ve replaced the radiator at least once and will probably need to do so in the future.
  • Overheating Jeep Wranglers is often attributed to radiator-related problems reported by owners.

It could be caused by coolant leaks or a malfunctioning radiator fan, for example. Owners and off-road enthusiasts should know what is the best radiator for Jeep TJ.

How Do You Choose A Good Radiator?

The standard features of a good replacement radiator for a rough terrain vehicle should include cooling, safety, longevity, durability, and affordability.

Your choice may also be influenced by other factors, such as the ease of installation and the level of customer service you receive.

Here are a few things radiators for Jeeps (especially the Jeep TJ model) may be looking for, including but not limited to:

  • Capacity of coolant
  • Lightweight and able to withstand some strain (due to rough terrain)
  • Installation is relatively simple
  • For racing or rough terrain cars that overheat more than normal cars, 3-row radiators are often preferred for their superior performance.
  • Cooling capability of transmissions
  • Longevity and durability, especially when used off road
  • Testing to ensure quality
  • The price

Additionally, the best models will work with both automatic and manual transmissions. Before buying, make sure the item fits.

Our Top Picks

These are our top picks of Best Radiators For Jeep TJ.

The STAYCO CU2101 radiator

The STAYCO CU2101 radiator
9.9/10 Our Score


  • It’s a proprietary feature you don’t see very often. Some may find this a deal-breaker when driving in extreme weather.

The CU2101 radiator has a high-density fin core, which increases efficiency and performance. In warmer weather, this means better cooling.

In addition, the thermal gasket makes this STAYCO unit ideal for use in colder climates (it also works well in heat).

The unit is not easy to install if you are not an experienced mechanic. Consider asking a professional mechanic for tips or assistance.

  • Even in challenging weather conditions, high-density fins lead to superior performance and efficiency
  • Cold resistance is enhanced by the thermal shock gasket
  • The best packaging to ensure that shipped items arrive in good condition
  • Reliability over the long term
  • Installation may require cutting and drilling before it can be installed

Radiator Direct Replacement: Mopar 5503 7652AA

Radiator Direct Replacement Mopar 5503 7652AA
9.4/10 Our Score


  • As with most MOPAR parts, this radiator provides superior cooling and fits easily into Jeep TJs. The fit and finish are OEM, so that is not an issue.

Plastic frames are usually used (as shown in the photo below), and they are known for their durability and reliability. Full metal construction is available, though the price can reflect that.

A full metal radiator is recommended if you do more off-roading. After buying plastic frames that won’t last as long as others on this list, you’ll settle for one.

Mopar’s CU2101 radiator fins are longer, which increases efficiency and performance. For Florida residents, this may be overkill if you live in a climate with large temperature swings.

It is relatively easy to install and remove this Mopar radiator. It should be similar to the radiator you are pulling out. In spite of the higher price, the longevity of the radiator typically matches or surpasses that of the original Jeep TJ radiator.

  • Even in challenging weather conditions, high-density fins lead to superior performance and efficiency
  • Cold resistance is enhanced by the thermal shock gasket
  • A perfect fit
  • Reasonable Price
  • There are some concerns about its longevity

  • To ensure performance in extreme weather conditions, this model is made from high-quality material and subjected to rigorous testing.

Tube wall thickness is another feature that enhances performance, durability, and longevity. The design includes OE Clevis pins and stress cuts to reduce stress and prevent warping during thermal expansion.

Although the fit and finish aren’t as good as the other radiators on this list, if you have more time and know-how than money, this may be the best option for you.

  • Enhanced performance, durability, and longevity due to material and engineering.
  • Designed to reduce stress, wear and tear
  • Seasoning and rigorous testing extend the life of the radiator
  • Reasonable Price
  • Doesn’t fit as well as competitors
  • Reliability issues

  • For 1987-2006, upgrade to a 4 row core aluminum radiator. Aluminum T-6061 is used to make this radiator.

For all weather and terrain conditions, it has a standard 4-core racing design that supports high performance with superior cooling (up to 45% more than normal).

This radiator fits like the OEM Jeep TJ radiator. However, it is better quality than what Mopar produces. Some people want and need this type of quality, but the price reflects that.

Radiator units like this are designed and manufactured to typically outperform the original units they replace.

  • Material and design that provide high endurance and efficiency
  • The 4-core design cools significantly better than the basic design
  • It’s expensive

The ALLOYWORKS 4 row full aluminum radiator may be overkill

  • Designed with a 4-row tube core, this radiator works with engines ranging from 2.4L-4.2L, as well as L4 and L6.

You are looking at the most bulletproof radiator on this list. It may be too much for most people, and they can get by with a cheaper radiator that fulfills all their needs. However, some want more, and this radiator should be your choice for your Jeep TJ.

Featuring a tube and fin design that increases surface area, the part promises 40% more cooling than stock designs and is fully tested for performance and endurance.

The Alloyworks brand has a good reputation. You can find them everywhere, and they make high-quality cooling products for your wildest 4×4 creations. Although their price reflects that, if you want perhaps the longest-lasting radiator on this list, look no further.

  • The 4-row design ensures superior performance in testing
  • Before being sold, the product is rigorously tested for performance
  • Tube-fin design and high-heat transfer material ensure significant cooling
  • Installs easily
  • The price is a bit high
