There’s a specific smell that strikes fear into the heart of any Jeep owner: the sickly-sweet aroma of hot coolant. It’s a scent that instantly signals trouble. For us, it started on a mild afternoon, climbing a modest grade. The temperature gauge on our trusty 2005 Jeep Liberty, which normally sat dead center, began its slow, unnerving creep towards the red. Pulling over and popping the hood confirmed our fears—a fine mist escaping from a hairline crack in the original radiator’s plastic end tank. After years of faithful service, the heart of the Liberty’s cooling system had finally given up. This isn’t just an inconvenience; it’s a critical failure that can lead to a warped cylinder head, a blown head gasket, and an engine rebuild costing thousands. The search for a replacement began immediately, leading us to a product that promised an upgrade over the factory unit: the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator.

Beyond the Box: What to Demand from an Aftermarket Radiator
A radiator is more than just a component; it’s the primary guardian of your engine’s health. It’s a key solution for dissipating the immense heat generated by combustion, ensuring your engine operates within its optimal temperature range. The benefits of a properly functioning radiator are profound: it prevents catastrophic engine damage, improves performance, and ensures the reliability you depend on, whether you’re commuting to work or exploring a remote trail. Neglecting it is a recipe for disaster, turning a manageable repair into a vehicle-ending expense.
The ideal customer for an aftermarket radiator is typically a hands-on vehicle owner, a DIY mechanic, or someone on a budget looking to avoid the high costs of OEM parts from a dealership. They understand the basics of their vehicle’s cooling system and are comfortable with the replacement process. However, this type of product might not be suitable for those who demand absolute, out-of-the-box perfection and have no tolerance for potential fitment adjustments or quality control inconsistencies. For someone who needs their vehicle back on the road the same day with zero complications, a premium, albeit more expensive, OEM or top-tier aftermarket brand might be a more prudent choice.
Before investing in any replacement radiator, consider these crucial points in detail:
- Fitment & Compatibility: This is non-negotiable. The radiator must have the exact core dimensions, inlet/outlet diameters, and mounting points as the original. Even a slight deviation can turn a two-hour job into a weekend-long nightmare of fabricating brackets or forcing hoses. Always double-check your vehicle’s specific requirements, including whether it needs ports for an integrated transmission cooler.
- Core Construction & Cooling Performance: The core is where the magic happens. Factory radiators often use a plastic tank crimped onto an aluminum core—a design prone to failure at the seam. An upgrade to a full aluminum radiator, like the one promised by DNA Motoring, offers superior heat transfer and durability due to its welded construction. Pay attention to the core thickness and fin density, as these factors directly impact its cooling efficiency.
- Build Quality & Durability: Look beyond the core material. Examine the quality of the welds, the thickness of the aluminum used for the tanks, and the integrity of any fittings or ports. A poorly sealed radiator cap interface or a weak petcock drain plug can create leaks that defeat the purpose of the new part. The internal transmission cooler, if present, must be robustly constructed to prevent the catastrophic mixing of coolant and transmission fluid.
- Packaging & Shipping Protection: A radiator is surprisingly fragile. Its thin aluminum fins can be bent or crushed with minimal impact, severely compromising its cooling ability. We have found that inadequate packaging is a major red flag, often indicating a manufacturer cutting corners elsewhere. The radiator should arrive in a sturdy box with ample protective foam or inserts to prevent any damage during transit.
While the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator presents an appealing option on paper, it’s always wise to see how it stacks up against the competition and understand the broader market.

First Impressions and Key Features of the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator
The arrival of the package was our first cause for concern. The radiator came in a surprisingly thin cardboard box, with only minimal styrofoam pieces for protection. This is a significant issue for such a delicate component. Upon unboxing, our initial inspection revealed several bent fins—a common consequence of poor packaging. While we were able to straighten them carefully with a small screwdriver, it was an immediate sign of potential issues ahead. We also noted a slight but perceptible bow across the unit’s length, which raised questions about manufacturing tolerances.
On paper, the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator boasts impressive specifications, including a full T-6061 aluminum core and direct bolt-on fitment. Visually, the welds looked adequate, and the unit felt lightweight as expected. However, we also found a curious disclaimer in the packaging stating the product was intended for “off-road use only,” a confusing and slightly alarming note for a part marketed as an OE-style replacement for a daily-driven SUV. This mixture of promising features and immediate red flags set the stage for a very telling installation and testing process.

A Deep Dive into Fit, Finish, and Failure Points
A radiator’s worth is ultimately determined by its real-world performance under pressure. An affordable price tag means nothing if the part fails, leaving you stranded and facing even more expensive repairs. We put the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator through a rigorous installation and testing process, and our findings, supported by a chorus of other user experiences, paint a very clear picture of this product’s strengths and, more significantly, its critical weaknesses.
Installation and the “Direct-Fit” Dilemma
The installation process for a radiator on a Jeep Liberty KJ 3.7L is straightforward for a moderately skilled DIYer. It involves draining the coolant, removing the fan shroud, disconnecting hoses, and unbolting the old unit. The DNA Motoring radiator is designed with the correct 20″ x 20″ core dimensions and mounting tabs that line up with the factory locations. On this front, it initially appeared to be a true direct-fit part. The hoses slid onto the inlet and outlet ports without much fuss, and the unit dropped into place.
However, the devil is in the details, and this is where we encountered the first major problems. Upon trying to install a brand new, OEM-spec radiator cap, we found the fit to be disconcertingly loose. It didn’t engage with the positive, tight feel of the original. This poor seal at the filler neck is a recipe for disaster, as it prevents the system from properly pressurizing, lowering the boiling point of the coolant and leading to overheating. This exact issue was echoed by multiple users who reported persistent leaks from under the cap, even after trying multiple new caps. Furthermore, our model came with fittings for an integrated transmission cooler, which our specific Liberty did not use. The manufacturer provided no plugs for these open ports, forcing us to source our own to prevent dirt and debris from entering the unused cooler over time—an annoying and unnecessary oversight. While the core may drop in, these critical finishing details betray the “direct-fit” promise and introduce immediate points of failure.
The Full Aluminum Core: A Promise Undermined by Poor Execution
The primary selling point of the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator is its T-6061 full aluminum construction. In theory, this is a significant upgrade over the stock radiator with its plastic end tanks. All-aluminum radiators dissipate heat more effectively and eliminate the weak point where plastic is crimped to aluminum, a common failure point on aging vehicles. When constructed properly, a full aluminum radiator should be more robust, more resistant to cracking from heat cycles, and provide a greater cooling capacity, which is a huge benefit for a vehicle that might be used for towing or off-roading.
Unfortunately, the potential of this superior material is completely squandered by subpar manufacturing and a lack of quality control. A high-performance material is useless if the welds are porous, the seams are weak, or the components are not built to withstand operational stress. We found that the theoretical benefits of the aluminum core were a moot point in the face of the unit’s overwhelming propensity to fail in other, more fundamental ways. It’s like building a house with a steel frame but using brittle, low-quality rivets to hold it together—the foundation of the design is compromised from the start.
Critical Flaws: Leaks, Cracks, and Catastrophic Failures
This is where our review turns from one of caution to one of stark warning. During our testing and evaluation of user feedback, we identified a pattern of alarming and often immediate failures. The most egregious issue we discovered, corroborated by a horrifying user report, was the failure of the internal transmission cooler. In one documented case, the cooler failed internally, allowing high-pressure coolant to flood the automatic transmission. This creates the infamous “strawberry milkshake” of death—a mixture of coolant and transmission fluid that destroys clutch packs and friction materials, necessitating a complete transmission rebuild. The cost of this radiator was refunded, but it was cold comfort after facing a multi-thousand-dollar transmission replacement caused directly by the defective part.
Beyond this catastrophic potential, more common leaks are rampant. We saw numerous reports of the unit leaking coolant as soon as it was filled for the first time. Others experienced failures within months, or even days. One particularly concerning failure mode is cracking at the point where the fan shroud mounts to the radiator. This indicates that the aluminum tanks are not strong enough to handle the minor stress and vibration from the fan assembly, a clear design or material flaw. Whether it’s a leak from the radiator cap, a split seam between the tank and the core, or a broken petcock drain plug, the evidence overwhelmingly points to a product that is not built to last. The fundamental job of a radiator is to hold coolant under pressure, and the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator frequently fails at this primary task, making it an unacceptably high-risk component to install in your vehicle.

What Other Users Are Saying
Our findings are not isolated incidents; they are part of a consistent pattern of feedback from other owners. While a few users reported a successful installation with “no issues,” these positive notes are heavily outnumbered by stories of frustration and failure. The most common thread is damage during shipping, with many receiving units with broken mounting pins, crushed fins, or even corrosion inside, suggesting they may have been previously returned items.
One user summarized the experience perfectly: “Three hours to install and as soon as coolant was added it started leaking.” Another warned of the long-term reliability after an initially successful install, stating, “Update: June 2022, radiator has cracked and is leaking. Only worked less than 2 years.” But the most damning feedback comes from the owner whose transmission was destroyed by the faulty internal cooler, a failure that cost thousands. Equally troubling are the reports of non-existent customer service, with the manufacturer and online retailers allegedly pointing fingers at each other, leaving the customer with a defective part and no recourse. This collective experience underscores a serious problem with the product’s quality and the company’s support.
Exploring Other Cooling Solutions: DNA Motoring vs. The Field

The AUTOSAVER88 radiator for Chevrolet sedans highlights the breadth of the aftermarket cooling market. Like the DNA Motoring unit, it aims to provide a cost-effective alternative to expensive dealership parts for common passenger cars. When comparing these products, the key differentiators are often build quality, weld integrity, and the quality of the plastic tanks (if not full aluminum). A Malibu owner would choose this for its value proposition, but would be wise to inspect it carefully upon arrival and check user forums for any known failure points specific to that brand and application.
3. Dorman 926-274 Radiator Mount Bushing 2 Pack
- Direct replacement - this radiator mount bushing matches the fit and function of the factory part on specified years, makes and models
- Ideal solution - this bushing is a reliable replacement for an original part that has failed due to fatigue
- Durable construction - this part is made from quality materials to ensure reliable performance and long service life
This alternative is not a radiator at all, but a crucial supporting component. Dorman is a well-respected name in the aftermarket for producing reliable, OE-spec miscellaneous parts. Including this here is vital because it underscores a key lesson: a radiator’s lifespan is heavily dependent on its mounting. Old, hardened, or broken radiator mount bushings fail to absorb engine vibration, transferring that stress directly to the radiator tanks and seams, which can cause even a well-made radiator to crack and fail prematurely. For someone installing any new radiator, replacing these inexpensive bushings at the same time is cheap insurance and a step that should never be skipped.
The Final Verdict: A High-Risk Gamble for Your Jeep Liberty
After a thorough evaluation, we simply cannot recommend the DNA MOTORING 02-06 Liberty 3.7L Full Aluminum Radiator. While the promise of a full-aluminum upgrade at a budget price is incredibly tempting, the execution is profoundly flawed. The risk of receiving a damaged unit is high, the prevalence of immediate and premature leaks is unacceptable, and the potential for a catastrophic internal failure that could destroy your transmission is a gamble no vehicle owner should have to take. The documented lack of effective customer support further solidifies our position.
Your vehicle’s cooling system is its lifeline, and compromising its integrity with a part that has such a poor track record is a classic case of being “penny wise and pound foolish.” The initial savings are quickly erased by the cost of wasted coolant, additional labor, and the potential for thousands of dollars in engine or transmission damage. If you’re considering this part, our expert advice is to look elsewhere. Invest a little more in a radiator from a brand with a proven reputation for quality and stand behind its products. Your Jeep Liberty will thank you for it. If you’ve weighed the risks and still wish to proceed, you can find more details and order the part here.
