If you own a 3rd Gen Toyota 4Runner, you already know it’s a beast on and off the road. These rigs have been the go-to for off-road fans for decades. Even after 20 years, you still spot them cruising around town or tackling tough trails. But as they age—like any classic—you might find some areas that could use a little TLC. Sure, the engine is a workhorse that can last forever, but the cooling system? That’s where things can get a bit dicey, especially if you’ve upgraded to bigger tires or are really pushing the limits.

Enter the CSF Heavy-Duty All-Aluminum Radiator, specifically designed for the 1996-2002 Toyota 4Runner. This isn’t just any radiator; it’s got a 2-row 42mm aluminum core that boosts fluid capacity and helps dissipate heat better than the stock setup. The real kicker is CSF’s exclusive B-Tube Technology, which ramps up heat transfer by about 15% compared to the standard oval tubes you see in most radiators. That’s a big deal when you’re out there crawling over rocks or towing heavy loads.

And let’s talk about airflow. This radiator features super-efficient multi-louvered fins that maximize airflow through the core, ensuring your 4Runner stays cool even when the temps rise. The end tanks are made from high-grade aluminum and are TIG welded to the core, so you’re looking at extra strength where it counts. Unlike the OEM design that’s crimped onto plastic end tanks—which can be a weak point—this setup is built to last.

Installation? A breeze. It’s designed as a true plug-and-play drop-in fit, meaning you won’t need to do any cutting or trimming. CSF even throws in pre-cut double-sided adhesive foam strips to seal the fan shroud against the radiator, which helps with airflow efficiency. Plus, it comes with a built-in heavy-duty transmission fluid cooler that connects to the OEM hoses. This is a game-changer if you’re dealing with added heat from towing or running oversized tires.

Speaking of oversized tires—when you upsize, you’re messing with the effective gear ratio. That means your engine and transmission have to work harder, generating more heat. But don’t sweat it; this CSF radiator is ready to handle that extra stress.

In short, if you want to keep your 3rd Gen 4Runner running cool and strong, this radiator is the way to go. It’s built with innovative tube and fin technologies and has been rigorously tested to ensure maximum airflow and heat dissipation.

CSF takes pride in the quality of its products and offers one of the best warranty’s in the industry. Please refer to the CSF warranty card in the shipping carton for details.

CSF warranty is applicable only to the original owner of the vehicle. Original paper work verifying the proof of purchase and pre-installation cooling system checklist signed by the professional installer is required to process warranty claims.

All warranty claims should be directed to the point of purchase. Due to CSF’s established agreements with Authorized CSF Warehouse Distributors, CSF is unable to handle and/or process warranty related calls/inquires from any individuals – all inquires/warranty related claims should be directed to the point of purchase or an authorized warehouse distributor.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.

Any repairs or alterations to the unit will automatically void the warranty.

Any form of abuse, including the use of improper coolant mixtures, damage caused by steam, corrosion etc and use on commercial vehicles voids the warranty. It is the vehicle owners’ responsibility to maintain the cooling system as specified in the owners manual.
