The Multiquip M3310503403 Inner Cooler Hose is a genuine OEM component designed for DCA150SSI and DCA150SSIU ultra-silent diesel generators. As a direct OEM replacement, it meets the exact material and dimensional specifications Multiquip requires for proper coolant routing in these machines. Sourced directly through authorized supply channels, this hose is confirmed to fit the DCA150SSI and DCA150SSIU without any adaptation. Keep part number M3310503403 on hand to simplify reordering when scheduled maintenance or an unexpected replacement comes due.
Key Features
- Genuine OEM Hose Material — Constructed to the original compound and wall-thickness specification, ensuring the hose holds rated pressure and resists heat cycling in continuous generator operation.
- Drop-In Fitment for DCA150SSI and DCA150SSIU — Manufactured to the exact routing geometry of the inner cooler circuit, connecting directly to the OEM fittings without cutting or reshaping.
- Confirmed Compatibility — Verified for DCA150SSI and DCA150SSIU ultra-silent series generators; always cross-reference part number M3310503403 before ordering.
- Sustained Cooling Circuit Integrity — A correctly seated inner cooler hose maintains consistent coolant flow through the system; a cracked or collapsed hose can cause overheating and unplanned generator shutdown.
- Fuel and Coolant System Safety — Proper hose condition is critical in enclosed generator housings where coolant leaks can compromise electrical components and create hazardous operating conditions.
The inner cooler hose carries coolant between the engine's cooling circuit and the charge-air or oil cooler assembly, maintaining the temperature balance the generator needs to run at full rated output. Over time, heat cycling, vibration, and coolant chemistry degrade hose material, leading to softening, cracking, or swelling that restricts flow. Replacing a worn hose promptly with the correct OEM part prevents coolant loss, protects downstream components, and keeps the generator performing within its designed thermal limits.
