Product Overview
A leaking core, crushed fins, internal scaling, or a radiator packed with jobsite debris can make a mini loader overheat whenever the hydraulic and engine load climb. This replacement heat exchanger puts a serviceable core back into machines using Bobcat number 6682991.
Overheating is not always the radiator. Check airflow, fan operation, cap, thermostat, coolant quality, hoses, and engine condition, then compare ports, mounts, and overall dimensions before installation.
This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.
