GM V6 Conversion Radiator

for

Early CJ's, 1946-1971

WORD

Radiator, KryoFlow, Early CJ Jeeps with GM V6 conversions, with integrated oil cooler

Our #K-ECJ11S is a high-performance conversion radiator, ideal for GM V6 engines installations into Early CJ Jeeps (1946-1971) that had the L134 / F134 or Buick V6 engines.

This aluminum radiator features two, one-inch rows and a down flow design. Included are two adjustable side brackets for the installer to achieve optimum depth, height and offset adjustment for their particular installation.

The radiator is equipped with a small transmission oil cooler. However, we typically recommend cooling your transmission with a separate cooler. See Related Products, below, and note that the oil cooler in the radiator could be used for engine oil cooling as well.

Applications & Compatibility

Compatible Jeeps

Early CJ Jeeps (1946-1971) that had the L134 / F134 or Buick V6 engines.

Compatible Engines

The radiator is designed for GM V6 engines installations.

Fans

These radiators can be used with mechanical or electrical fans. Mechanical fans will require that a shroud be fabricated to match the position of your engine fan. Electric fans are strongly recommended for ease. We recommend our #FX3300-EC fan and shroud kit, in Related Products, below.

Tough, flexible stainless lines with easy sealing AN fittings. We've installed these on so many Jeeps and they're an in-and-done type product and compatible with our #OC-H7B cooler, adjacent.

Stainless coolant overflow tank

#OT6082, Tank, overflow, polished stainless, 3” x 10”, includes cap and bracketry

This is the overflow tank we reach for when doing a conversion in pretty much any Jeep. We love the stainless steel construction, simplicty and ease of mounting. They take up little room and can tuck into a variety of locations. It will outlast all of those cheap plastic ones from the factory.


Installation Requirements

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.

Tubular style crossmembers will have to be modified or, better, replaced when doing a Chevy Small Block V8 or GM Gen. III+ V8 installation. The installer may already be performing this operation for radiator, steering or strength purposes. V6 and shortened V8 installations do not require this step for the sake of the engine, but the conversion radiator will probably require the removal of the crossmember. The use of box steel tubing, welded into the frame channels, makes for the cleanest and easiest upgrade. It is also possible to make it such that the steering shaft (on Saginaw steering converted Jeeps) pass through a drilled hole in this crossmember.
