The Multiquip M1311500903 Intercooler Hose Upper Lower is a genuine OEM component designed for DCA36SPXU4F and DCA45SSIU4F series ultra-silent diesel generators. As a direct OEM replacement, this hose set is manufactured to the exact specifications required to maintain proper charge-air routing on these generator platforms. Correct fitment is confirmed across DCA36SPXU4F, DCA45SSIU4F, and DCA45SSIU4FC8 variants, giving operators confidence that the part will seat and seal correctly on installation. DHS Equipment sources this part directly through authorized Multiquip channels, so you receive a genuine component backed by the brand.
Key Features
- OEM-Grade Hose Construction — Engineered to withstand the elevated temperatures and pressures present in turbocharged diesel charge-air systems, maintaining integrity across extended run cycles.
- Exact-Match Upper and Lower Configuration — Supplied as an upper and lower hose set matching the original routing geometry, so both connections are addressed in a single replacement.
- Confirmed Fitment for DCA-Series Generators — Compatible with DCA36SPXU4F, DCA45SSIU4F, and DCA45SSIU4FC8 super-silent and ultra-silent generator models, including 60Hz variants.
- Protects Turbocharger and Engine Performance — A properly sealed intercooler hose maintains correct boost pressure delivery to the engine, preserving rated output and fuel efficiency under load.
- Genuine OEM Sourcing — Supplied through authorized Multiquip distribution, ensuring the part meets the original design specification for these generator models.
The intercooler hose routes compressed, heat-saturated air from the turbocharger outlet through the intercooler and into the engine intake. Cooling this charge air increases its density, allowing the engine to produce its rated power output efficiently. When an intercooler hose cracks, collapses, or loses its seal, boost pressure drops, the engine loses output, and on turbocharged diesel generators this can trigger derating or protective shutdown — directly affecting the generator's ability to supply stable power to connected loads. Replacing a failed hose promptly with a correctly specified part restores the charge-air circuit to its designed operating condition.
