Engine Block Heater for Dodge Challenger (2009-2022) 5.7L Hemi

Cold-Weather Protection Engine Block Heater for 2009-2022 Dodge Challenger (LC / LA)

What it Does: The Engine Block Heater pre-heats engine coolant and oil on the 2009-2022 Challenger to ensure reliable sub-zero starting, reduce dry-start friction, and minimize engine warm-up cycle times.

The Stock Dodge Challenger Cold-Start Friction Problem

During freezing ambient conditions, the cast-iron cylinder block of the 5.7L Hemi pulls thermal energy out of motor oil, significantly increasing kinematic viscosity. This cold-soak condition prevents immediate oil pressure delivery to critical valve lifters, pushrods, and crank journals upon ignition. Repeated cold dry-starts accelerate cylinder wall scuffing, place heavy electrical demand on the starter motor, and delay entry into closed-loop ECU fuel mapping.

The Engineering Solution

Engineered for direct core-plug immersion, this 600-watt, 120-volt heating element utilizes conductive heat transfer inside the water jacket, warming engine coolant via natural thermal convection throughout both cylinder banks. Constructed with a corrosion-resistant copper alloy immersion element and an insulated, routed 7-foot power harness, it safely brings the 5.7L Eagle Hemi up to operating temperature before ignition, eliminating extreme cylinder friction and excess unburnt hydrocarbon emissions.
