R123 / R124 Radiator Cap Testing Adapter

Replace a lost or damaged radiator cap adapter or add a new one to your existing kit with this STEELMAN 60403 R123 / R124 Radiator Cap Testing Adapter. This cooling system adapter acts as a second stage bridge between a pressure pump assembly attached to a regular radiator testing adapter to allow the seal testing on the existing radiator cap to ensure it is still functioning properly. This black nylon coupler is designed for use on smaller radiator caps used in Honda, Nissan, Mazda, Mitsubishi, and Toyota vehicles. Compatible with pressure pumps used in the STEELMAN 97332 Cooling System Test and 60025 Cooling System Test and Purge / Refill Kits.
