The Honda 19104-758-000 Reserve Tank Tube is a genuine OEM replacement designed for H4514 and H4518 lawn tractors. As a direct Honda OEM component, this tube is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation. Confirm your tractor's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and fitment can vary across production runs.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this tube matches the original part exactly in dimensions and material form, eliminating the guesswork of adapting an off-spec replacement.
- Correct Coolant Routing — maintains the intended flow path between the reserve tank and the cooling system, ensuring the system operates as Honda designed it for the H4514 and H4518.
- Serial Number Verification Recommended — Honda updates parts at defined production breaks, so cross-check your tractor's serial number against the fitment table to confirm this is the right tube for your unit.
The reserve tank tube connects the coolant overflow or reserve tank to the cooling circuit on the H4514 and H4518 lawn tractors, allowing coolant to move between the system and the reservoir as the engine heats and cools. This controlled transfer keeps the coolant level stable and prevents the system from drawing in air. A cracked, kinked, or deteriorated tube disrupts that flow, which can lead to erratic coolant levels and potential overheating over time.
