The Honda 90131-ZE3-790 Oil Drain Plug is a genuine OEM Oil Drain Plug designed for a wide range of Honda engines and equipment, including GX240, GX270, GX360, and GX390 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, and H5013 and RT5000 multi-purpose tractors. As a genuine Honda part, it is manufactured to the exact standards of the original component it replaces, ensuring a correct, leak-free fit every time. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks across production runs.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's original specification, ensuring the drain opening seals completely and holds oil pressure without weeping or leaking between service intervals.
- Exact Thread Match — engineered to the correct thread pitch and diameter for a proper seat against the oil pan, so installation is straightforward and no thread damage occurs during torquing.
- Broad Honda Compatibility — listed for GX240, GX270, GX360, and GX390 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, and H5013 and RT5000 multi-purpose tractors; verify your serial number against the fitment table to confirm the right plug for your unit.
- Protects Engine Oil Supply — a properly seated drain plug keeps oil in the sump where it belongs; a damaged or ill-fitting plug risks oil loss, which leads directly to accelerated engine wear or seizure.
The oil drain plug seals the drain port at the base of the engine's oil sump, keeping crankcase oil contained during normal operation and releasing it cleanly during scheduled oil changes. It carries a sealing surface — typically a tapered thread or a crush washer seat — that must form a leak-tight joint to prevent oil from escaping between service intervals. When the plug's threads are stripped, the seating surface is damaged, or the plug is simply missing, the engine loses oil, starving bearings and moving parts of lubrication and risking rapid internal damage. Replacing a worn or damaged drain plug with a genuine Honda part restores that seal and ensures every subsequent oil change drains and reseals correctly.
