Multiquip EE47790 Block Heater Kit 500kW Volvo TAD1640

The Multiquip EE47790 Block Heater Kit 500kW Volvo TAD1640 is a genuine OEM component designed for TAD1640 series super-silent generator sets. As a direct Multiquip OEM part, EE47790 is engineered to integrate precisely with the TAD1640 engine architecture, ensuring the heater circuit operates exactly as the original design requires. This kit is the correct, verified replacement for TAD1640-equipped units and is stocked by DHS Equipment for fast fulfillment. If your generator operates in cold climates or experiences extended idle periods between use, this is an essential service part to have on hand.

Key Features

• Genuine OEM Engine Heater Specification — Sourced directly from Multiquip, this block heater kit meets the exact thermal output and electrical ratings required by the Volvo TAD1640 engine — no guesswork on compatibility or wattage.
• Drop-In Installation for TAD1640 Engines — Designed to mount directly to the TAD1640 engine block using the OEM connection points, allowing for a straightforward service replacement without fabrication or adaptation.
• Fits TAD1640 Generator Sets — Confirmed fitment for Multiquip TAD1640 super-silent generator models. Always verify your model code and serial number before ordering.
• Protects Engine During Cold-Start Conditions — A functioning block heater keeps engine coolant and oil at an optimal pre-start temperature, preventing the wear and hard-starting that occur when a large diesel engine turns over cold.
• Critical for Generator Reliability in Low-Temperature Environments — On standby and prime power generators, block heater failure can result in sluggish starts, excessive engine wear, or failure to start entirely during emergency load demands — making timely replacement essential.

A block heater is an electric heating element installed in or around the engine block that warms the engine coolant — and by extension the engine oil — while the machine is not running. On large diesel generators like the TAD1640, this is especially important because cold oil is thick and slow to circulate, placing significant stress on bearings and cylinder walls at startup. When a block heater fails or is absent, repeated cold starts accelerate internal engine wear and can compromise generator readiness in standby applications where immediate startup is critical.
