Radiator Modification Connections & Fittings

The Northern Radiator Modification Connections & Fittings kit (MPN Z12013) is designed for vehicle builders and mechanics who are upgrading or modifying their cooling systems. This kit addresses common compatibility issues that arise when integrating aftermarket radiators or modified water pump configurations with OEM components.

The fittings in this kit feature precision adapters that bridge the gap between factory cooling lines and performance radiators, ensuring leak-free operation. They are designed with SAE-standard threads and include barbed or flanged designs that create secure connections to prevent hose slippage. The fittings are lightweight, weighing 0.32 lbs, making them suitable for tight engine bay routing.

Installers will appreciate the variety of fitting sizes included in the kit, which helps minimize the need for multiple specialty purchases. This kit is particularly beneficial for custom radiator conversions, turbo cooling upgrades, and LS engine swaps into classic vehicles, ensuring that projects can proceed without delays due to port mismatches.
