Heater, Engine Block: Description
WARNING: This page is about a different car, the 2020 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
The power cord must be secured in its retainer clips, and not positioned so it could contact linkages or exhaust manifolds and become damaged.
The block heater (2) is operated by ordinary house current (110 Volt A.C.) through a power cord and connector located in the engine compartment. The heater is mounted in a bore in the engine block and held in place by a retaining clip (1).
