GM V8 Conversion Radiator

for

Early CJ's, 1946-1971

Our #K-ECJ30H is a high-performance conversion radiator, ideal for GM V8 engines installations into Early CJ Jeeps (1946-1971) that had the L134 / F134 or Buick V6 engines. This radiator requires the Installer to cut the spot welded on factory shroud from the Jeeps grill. This provides maximum amount of room in the engine bay for your new GM V8 engine.

Product & Features

Upgrade your early Jeep CJ's cooling system with our K-ECJ30H and K-ECJ10H High-Performance Aluminum Radiators, engineered for seamless integration and optimal efficiency. Designed and fabricated in-house, this radiator is a perfect match for enthusiasts aiming to equip their Jeep with a GM V8 engine, offering superior cooling in demanding conditions.

Features:

Optimized for Early Jeep CJs: Specifically tailored for Jeep CJ models pre-1972, ensuring a perfect fit for your classic off-roader.
Cross Flow Design: Incorporates two 1.25" rows in a cross-flow configuration, maximizing cooling efficiency and engine performance.
Custom Fit: Features notches for installation between the headlights, maximizing engine bay space.
Easy Installation: Though installation requires cutting the stock metal fan shroud back due to its spot-welded design, all the homework is already done. This modification allows the radiator to be positioned further forward. This crucial adjustment creates ample space in the engine bay for a GM V8 engine swap.
Built to Last: Every radiator is meticulously fabricated and welded in-house.
Quality Assurance: Pressure-tested for leaks and subjected to a rigorous thermal bench test to guarantee superior cooling efficiency and reliability.

The K-ECJ30H radiator features both coolant ports on the passenger side, making it the ideal choice for GM Gen III/IV engines. For those with GM Gen I/II engines, our K-ECJ10H model, with hose ports on opposite sides, offers a better fit. Ensure you pick the model that aligns with your engine specifications to achieve the best results.

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

Engines

The radiator is designed 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 also a possibility. We recommend the bespoke kit listed below which will come installed to the radiator if ordered together ready to install.

**Fan/shroud assemblies ordered with the radiator come pre-assembled for a “drop-in” package saving substantial time on your part.

Installation Requirements

Typical mechanics hand tools 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.

It may be required for the installer to drill holes into the Jeep pre-flange, according to the installations requirements.

Removal and relocation of the factory cross member is required on 134 engine grilles, as discussed in our Early CJ Knowledge Base article linked below.
