This is a multi-purpose, Y-shaped coolant hose (commonly called a "cactus hose") for Mack E7 and ASET diesel engines. It is typically installed at the lower thermostat housing and carries engine coolant between the block, thermostat, and radiator. Over time, this molded rubber hose can become brittle, swell, or develop cracks, leading to coolant leaks, so it is replaced during cooling system repairs or preventive maintenance.
