Diesel Exhaust Fluid Heater Compatible with Freightliner

In this review of the A-Premium diesel exhaust fluid heater the bottom line is simple: this part is for owners of 2010-2016 Freightliner and Mercedes-Benz Sprinter 2500/3500 vans with the V6 3.0L diesel who need a direct-fit DEF heater that matches OEM fit and function. The reviewer found the unit to be well engineered for its role, with deliberate protection against fluid intrusion and a housing designed to match original equipment. For anyone chasing a replacement that focuses on compatibility and longevity, this DEF heater delivers the primary reassurance most buyers want: a component built to meet or exceed OEM specifications.

Key Features

• Vehicle Fitment: Direct compatibility with Freightliner and Mercedes-Benz Sprinter 2500 and 3500 models from 2010 through 2016, making installation straightforward for the specified V6 3.0L diesel vehicles.
• OEM Reference Numbers: Supplied to match OE part numbers such as 904379 and 9064700553, which helps ensure the heater will replace the original unit without modification.
• Protected Design: The heater includes additional protection from fluid intrusion, reducing the risk of failure in the DEF system when exposed to harsh conditions.
• Durability Testing: The design is validated with cyclical heater element fatigue testing, which supports long-term reliability under repeated thermal cycles.
• Connector and Sensor: Uses a female connector with a 4+3 terminal arrangement and a resistor type level sensor to match the original electrical interfaces.

Who It's For

This DEF heater is aimed at technicians, fleet managers, and independent owners of Sprinter 2500 and 3500 vans with the V6 3.0L diesel from model years 2010 to 2016 who need a like-for-like replacement part that fits with minimal fuss. It particularly suits those who value parts that meet OEM reference numbers and who prefer components that have undergone fatigue testing for the heater element.

Buyers who drive vehicles with the L4 2.1L diesel or owners of models outside the listed years should look elsewhere, since this unit explicitly does not fit the L4 2.1L diesel application. It is not marketed as a universal heater, so confirm vehicle info before ordering.
