Industrial 88-22170 Generator Upper Radiator Hose

The 88-22170 generator upper radiator hose is the coolant conduit used in USGI MEP-804A and MEP-814A portable generators. It connects the engine cooling circuit to the radiator, carrying heated coolant and returning cooled fluid to help maintain optimal engine temperature during operation. This hose is cataloged with part number 88-22170 and NSN 4720-01-374-0783, enabling precise ordering and replacement within government-issue generator maintenance programs. Designed for the specific cooling system geometry of MEP-804A/MEP-814A units, it helps ensure a secure fit to prevent leaks and maintain proper pressure in the cooling loop. Typical applications include field service, depot repair, and routine maintenance of military and industrial generators that rely on these models. Replacing the upper radiator hose with the correct part supports reliable performance under load and in demanding environments. When ordering, verify compatibility with MEP-804A and MEP-814A configurations and cross-reference the part number 88-22170 and NSN 4720-01-374-0783 to ensure an exact match.
