Novak's HD cross-flow radiator for 1997 to 2006 Jeep Wranglers is made to be the most innovative on the Jeep aftermarket. Jeep engine swappers have the challenge of keeping more powerful engines cool within the confines of one of the smallest grill spaces in the automotive industry.
These radiators are fabricated in-house at Novak since 2012, where we have relentlessly pursued radiators which have:
Our radiators do not feature integrated transmission coolers, as we choose to focus the unit's entire cooling power on the engine. More on this, below.
Fan/shroud assemblies ordered with the radiator come pre-assembled for a "drop-in" package saving substantial time on your part.
The classic Small Block Chevy version of our radiator features the 1-1/2" diameter top inlet on the driver's side and the lower 1-5/8" outlet on the passenger's side.

The LS version of our radiator features a 1-1/2" diameter top inlet on the passenger's side and the lower 1-3/8" outlet on the passenger's side.

The Ford & AMC version of our radiator features a 1-1/2" diameter top inlet on the passenger's side and the lower 1-5/8" outlet on the driver's side.
Because modern engines run a bit hotter than earlier engines and automatic transmissions prefer to be kept at cooler temperatures, we at Novak choose to offer radiators without an integrated automatic transmission cooler option. These coolers are more effective run as separate units. This method is confirmed by trends in the OEM automotive industry. See Related Products, below, for our recommended transmission cooler for most Jeeps.
Note that the bungs and brass plugs provided in the Novak radiator tanks are for temperature sensors and steam vents, not for transmission cooler lines.
Unlike other radiator systems on the market the KryoFlow system is designed to meet the needs of a Jeep in an off-road environment. Typical Jeep use differs from a race or street car, which don't see the strains, flex and jarring typical of off-road use. Instead of using brackets welded to the tanks, our cradle grips and cushions the radiator with a compressible, heat-resilient silicone padding that allows the radiator to "float" eliminating fatigued radiator joints. Featuring a total of six isolators; two on the bottom hold pins positively locating the radiator while the tanks are held by two on either side. The bracket holds the radiator securely yet absorbs the twists and bumps of the trail isolating potential strains.
The radiator may be compatible with many electric and conventional mechanical fans. We recommend our FX Series Electric Fan which combines a high-powered fan and integrated shroud into one effective package, available in Related Products, below.
If you order your fan at the time of your radiator order, we will join them together for you and package them for combined shipment.
These assemblies are designed to fit the 1997-2006 Wrangler TJ and LJ models with engine conversions appropriate to the model selected. The dimensions of the radiator are 24.25"W x 18.5"H x 7.5" D. Because of the extra radiator thickness these will not work with the stock 4.0L engine due to length constraints of the inline 6 cylinder configuration.
Typical mechanics hand tools are required along with the appropriate hoses, clamps and coolant required with a normal radiator swap. After installing this upgrade radiator, we recommend that the installer should verify fan-to-radiator clearance and engine mount integrity before operating the Jeep.
Our radiators come with a 1-year / 100% warranty for defects in materials or workmanship, which is prorated and Novak will cover the cost as follows:
