Key Features

• Genuine OEM Construction — Manufactured to original equipment specifications, ensuring the water heater delivers the correct thermal output and fitment geometry for the DCA70USI generator cooling system.
• Direct Replacement for DCA70USI — Engineered specifically for the ultra-silent generator platform, connecting directly to existing coolant lines without improvised adaptation.
• Supersession Notice — Multiquip has updated this part; the current active replacement is FC601-501. Always confirm the latest part number with your dealer or the Multiquip parts system before placing your order.
• Cold-Weather Readiness — A functioning water heater keeps engine coolant at an optimal pre-start temperature, supporting reliable cold-weather starts and protecting engine components from thermal stress during initial crank.
• Fits DCA70USI Ultra-Silent Generators — Designed for the DCA ultra-silent diesel generator series, keeping the cooling and pre-heat circuit operating as intended during standby and operational cycles.

A water heater on a diesel generator is a block or coolant heater that keeps engine coolant warm while the unit is on standby. By maintaining elevated coolant temperature, it allows the engine to reach operating condition faster and reduces wear caused by cold starts — a particular concern for generators that must come online quickly in emergency or critical-power applications. When the water heater fails, the engine may start harder in cold conditions, run rough during warm-up, and experience accelerated cylinder wear over time.
