The Honda 19103-PH7-010 Reserve Tank Hose is a genuine OEM Reserve Tank Hose designed for GX360 and GX640 horizontal shaft engines. As a direct Honda OEM component, this hose is manufactured to the same specifications as the original, ensuring a proper connection between the cooling system's reserve tank and the engine. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct part number 19103-PH7-010 must match your specific unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this hose matches the original component in dimensions and construction, eliminating guesswork on fit
- Correct Coolant Routing — maintains proper fluid transfer between the reserve tank and the engine's cooling circuit, preventing air intrusion or leaks that compromise cooling performance
- GX360 and GX640 Fitment — built specifically for these horizontal shaft engines; verify your serial number against the fitment table to confirm the right part for your build
- Cooling System Integrity — a cracked or deteriorated hose leads to coolant loss and the risk of overheating; replacing a failed hose with this OEM part restores the system to its original operating condition
The Reserve Tank Hose carries coolant between the engine's overflow or reserve tank and the main cooling circuit, allowing the system to expand and contract with temperature changes without losing fluid. When the engine heats up, excess coolant is routed into the reserve tank; as it cools, that fluid is drawn back in. A hose that is cracked, kinked, or has lost its sealing at the connections will cause coolant loss, leading to overheating and potential engine damage over time.
