The Honda 19501-ZA0-920 Upper Water Hose is a genuine OEM component designed for GX360 horizontal shaft engines. As a factory-original part, it meets Honda's exact specifications for routing, diameter, and connection — ensuring a proper seal and correct coolant flow within the engine's liquid cooling circuit. If your current hose is cracked, softened, or leaking, this is the correct direct replacement to restore the system to spec.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this hose matches the original in length, diameter, and end configuration, so it seats correctly on the GX360's cooling circuit connections without trimming or adapting.
- Correct-Fit Replacement for the GX360 — built specifically for GX360 horizontal shaft engines; verify your engine's serial number against the fitment table to confirm this is the right hose for your production range.
- Cooling System Integrity — a hose that is cracking, swollen, or leaking coolant puts the engine at risk of overheating; replacing it promptly with the correct OEM part keeps the liquid cooling circuit sealed and operating as designed.
The Upper Water Hose is part of the GX360 engine's liquid cooling system, routing coolant between the water jacket and the cooling components to regulate engine temperature during operation. A properly sealed hose maintains consistent coolant flow and prevents heat from building to damaging levels inside the engine. When this hose deteriorates — through cracking, softening, or connection wear — coolant loss follows quickly, and continued operation without it can lead to serious engine damage.
