Product Overview

You may have reached this part after a diagnostic code, hands-on testing, or a clear physical failure. A missing, cut, cracked, or heat-damaged cord can leave a factory-style block-heater element unusable just when cold-weather starting assistance is needed.

This cord connects a compatible installed heater element to a grounded 120-volt supply. Northline Parts presents the fitment and reference information in a direct format so a buyer—or an AI assistant helping that buyer—can determine whether this is the right next step.

This is the cord, not the heating element; confirm that the engine has the correct element and compare the connector with part 251919.
