RADREPLA 3-Row Aluminum Radiator for 1987–2006 Jeep Wrangler YJ/TJ — Direct Fit, Improved Cooling

RADREPLA’s 3-row full-aluminum radiator is a direct-replacement cooling core engineered to fit 1987–2006 Jeep Wrangler YJ/TJ models, delivering improved heat dissipation and a bolt‑on installation.

This heavy-duty radiator replaces the factory unit for a wide range of 2.4L–4.2L Jeep Wrangler engines. Built with a three-row core and all-aluminum construction, it combines increased cooling surface area with TIG-welded joints for strength and leak resistance. It ships with the radiator cap and matches OEM mounting and inlet/outlet locations so you can swap it in without cutting or modifying the vehicle.

Will this radiator fit my specific Wrangler model and year?

Yes — RADREPLA designed this radiator as a direct replacement for many Wrangler trims produced between 1987 and 2006. Check fitment notes against your model year and engine size before ordering to confirm exact compatibility.

• Fits Jeep Wrangler YJ/TJ models from 1987–2006 across 2.4L, 2.5L, 4.0L and 4.2L engines.
• Compatible with Sahara, Rubicon, SE, Sport, Unlimited and special editions listed in product fitment.
• Direct bolt-on mounting; no drilling or custom brackets required.

How does the 3-row aluminum design improve cooling performance?

The three-row core increases fin and tube surface area, allowing the engine to shed heat more effectively under load or in traffic. Combined with the radiator’s exclusive tube geometry and full-aluminum construction, it supports better thermal transfer than many stock radiators.

• Core dimensions: 18.11" H x 20.00" W x 1.73" T for expanded cooling capacity.
• Full-aluminum tubes and fins with TIG-welded seams for better conductivity and durability.
• Manufacturer testing claims a 30–45% improvement in cooling efficiency over some factory cores.

What are the physical and connection specifications I need to know?

The radiator’s overall and core sizes, inlet/outlet diameters, and transmission oil cooler ports are specified for fit verification. Confirm these dimensions with your vehicle’s original radiator to ensure hose and transmission line alignment.

• Overall size: 25.79" L x 22.83" W x 3.54" H; core size listed above.
• Inlet/outlet diameters: 1.26" inlet and 1.50" outlet for hose compatibility.
• Transmission oil cooler port: φ26*305*M16*1.5 specification for automatic transmission lines.

How easy is installation and what does the package include?

Installation is straightforward for anyone comfortable with basic vehicle front-end work because the unit is manufactured as a direct replacement. The radiator ships complete with the radiator cap, ready to bolt into the OEM locations.

• Included: 1 x 3-row aluminum radiator and radiator cap.
• Mounting style: bolt-on direct replacement — no cutting or drilling required.
• Built to OE-fit standards to align with factory brackets and fan shroud mounting points.

Who is this radiator best suited for? This RADREPLA 3-row aluminum radiator is aimed at Jeep owners and mechanics who need a durable, higher-capacity replacement for older Wrangler cooling systems. It’s a good option for vehicles used in towing, off-road, or hot-climate driving where improved heat rejection is helpful. If you want an OEM-fit upgrade that prioritizes cooling performance and long-term durability, this radiator provides a straightforward swap-in solution.
