Multiquip EE54798 110 Volt Coolant Heater Kit

The Multiquip EE54798 is a genuine OEM 110 Volt Coolant Heater Kit designed for DCA-series Super-Silent and diesel powered generators including the DCA70, DCA150, DCA220, and DCA300 families. As a direct OEM replacement, EE54798 is built to the same specifications as the original component installed at the factory, ensuring a correct installation without guesswork. This kit is compatible across a wide range of John Deere-powered DCA models in both standard and Tier 4 Final configurations.

Key Features

• Genuine OEM Heat Output Spec — Matched to the original 110-volt electrical rating so the heater draws correct current and reaches proper coolant temperature without overloading the circuit.
• Direct-Fit Kit Configuration — Supplied as a complete kit with the components needed to connect directly to the existing coolant system and electrical supply on compatible DCA generators.
• Broad DCA Series Compatibility — Confirmed fitment across DCA70, DCA150, DCA220, and DCA300 Super-Silent and diesel powered generator models, including Tier 4 Final variants.
• Cold-Weather Starting Performance — Keeps engine coolant at an elevated temperature during standby so the generator starts quickly and reaches operating temperature faster in cold ambient conditions.
• Fuel System and Engine Protection — Pre-warming coolant reduces cold-start fuel dilution and cylinder wear, extending engine service life on high-hour standby and prime power applications.

A coolant heater keeps the engine block warm while the generator is on standby, allowing the unit to reach operating temperature rapidly when called to run. On large diesel generators used for standby or prime power, a cold start without pre-heated coolant increases wear on cylinder walls, pistons, and injectors, and can cause the engine to struggle under load before it warms up. When the heater element fails or the kit components degrade, the generator loses that thermal head start, which is especially critical in low-temperature environments or emergency-power applications where immediate, reliable output is required.
