The Multiquip Y0377103140 SCR Coolant Line is a genuine OEM component designed for DCA70SSIU4F super-silent diesel generators. As a direct OEM replacement, this part is sourced to the original specification, ensuring it integrates correctly with the existing cooling circuit without adaptation. Confirmed fitment for the DCA70SSIU4F series makes this a straightforward service replacement for technicians maintaining these units in the field or depot.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional spec for the cooling circuit, so the line seats, seals, and routes exactly as the factory-installed part did.
- Direct Bolt-In Replacement — Connects to existing fittings and brackets on the DCA70SSIU4F without rework, keeping service time to a minimum.
- Confirmed DCA70SSIU4F Fitment — Verified for the DCA70SSIU4F super-silent Tier 4 diesel generator series, covering both standard and 60 Hz configurations.
- Cooling System Integrity — A correctly routed and intact coolant line maintains proper coolant flow to and from the SCR system, preventing thermal stress that can lead to engine overtemperature faults.
- Emissions System Compliance — The SCR (Selective Catalytic Reduction) circuit is part of the Tier 4 emissions control system; using a correctly spec'd OEM line helps keep the aftertreatment system functioning within regulatory requirements.
The SCR Coolant Line carries engine coolant through the Selective Catalytic Reduction aftertreatment system, where heat from the coolant is used to maintain the SCR catalyst and associated components at the temperatures required for effective diesel exhaust fluid (DEF) processing. Without adequate coolant flow through this circuit, the SCR system can experience temperature faults, leading to reduced generator output or automatic shutdown. A cracked, kinked, or leaking line will compromise both cooling efficiency and emissions performance, making timely replacement essential on Tier 4-compliant machines like the DCA70SSIU4F.
