Transmission Oil Cooler 23 Plate & 8" Fan Combo (24V)

The Hydra-Cool^® DC699 Combo Kit is an effective and economical solution designed to maintain your transmission at its optimum operating temperature. This high-performance kit is specifically engineered for 24V systems, providing essential cooling during sustained high-speed driving, stop-and-start traffic, heavy towing, and demanding 4WD conditions.
