Product Specifications & Package Includes

Package Includes: 1 × 3-row 44 mm AA5052 aluminum radiator and 1 × CNC-machined radiator cap.

Signs Your Radiator Needs Replacement

• The engine runs hotter than normal or overheats during idling, cruising, climbing, or warm-weather use.
• Coolant leaks appear around the radiator, seams, hose connections, drain area, or lower corners.
• The coolant level drops repeatedly without an obvious hose leak.
• The original radiator shows corrosion, damaged fins, internal blockage, or weakened seams.
• The temperature gauge fluctuates during city traffic, highway driving, or light hauling.
• The existing radiator no longer provides stable cooling for a restored or modified classic vehicle.

Replacing an aged radiator helps restore coolant circulation and heat transfer, reducing the risk of repeated overheating and related engine damage.

Key Features & Benefits

3-Row 44 mm AA5052 Aluminum Core: The larger core provides increased cooling surface area and coolant capacity for compatible classic Ford applications.

Classic Ford Fitment: Designed around CU433-style mounting and hose locations for compatible Bronco and F-Series vehicles.

Stable Cooling in Demanding Conditions: Helps support engine temperature during commuting, cruising, warm weather, traffic, light hauling, and restoration use.

CNC-Machined Radiator Cap Included: Supplied as part of the package for the specified radiator configuration.

Leak Tested: Each radiator is checked before shipment to support dependable cooling-system performance.

Installation Notes & 4-Step Guide

Important: Classic vehicles may have modified engines, brackets, pulleys, hoses, fans, or engine-bay layouts. Compare the original setup carefully before installation. Professional installation is recommended.

1. Drain: Allow the engine to cool completely, remove the radiator cap carefully, and drain the old coolant into a suitable container.
2. Remove: Disconnect the radiator hoses, overflow hose, fan shroud or related components, and factory mounting hardware. Remove the old radiator carefully.
3. Install: Compare the dimensions and connection points, transfer reusable brackets or cushions when required, and install the new radiator using the compatible mounting locations.
4. Refill & Bleed: Reconnect all hoses, refill with the vehicle manufacturer-recommended coolant mixture, bleed trapped air, and inspect all connections for leaks.

After installation: Inspect the hoses, clamps, radiator cap, thermostat, cooling fan, water pump, and engine-bay clearance. Recheck coolant level and all mounting points after the first drive and again after the engine cools.
