Radiator coolant hose (49 mm inner diameter) for Caterpillar machinery (CAT 320 series, C6.4 / 3066) — a direct replacement for the original Caterpillar 7Y-1942. It transfers coolant between the engine and the radiator. Hoses harden and crack with heat cycles and can weep or burst, causing coolant loss and overheating. Replaced at cooling-system service or when the hose shows bulging, cracking or soft spots. Supplied as one moulded hose. Confirm the engine/machine model before ordering; fit with new clamps and never reuse a removed hose.
