Jeep Block Heater Locations: A Complete Guide for SUV Owners

Where is my Jeep block Heater Located?

In colder climates, a block heater is essential for the longevity of your engine. However, many new Chrysler, Dodge, Jeep, and RAM vehicles don't come with them as a standard feature.


Can’t find your Jeep’s block heater cord? Adrian at Redwater Dodge shows you where to locate the block heater on Jeep models to ensure easy winter starting.

Jeep Cold Weather FAQs


Q1: How do I know if my Jeep has a block heater?

A1: The easiest way to check is to look for a thick black electrical cord (usually with a capped 3-prong plug) near the battery on the passenger side. You can also check your original window sticker (Monroney label) or call our service department with your VIN, and we can look up your build sheet.


Q2: Why doesn't my vehicle have a block heater cord?

A2: Many manufacturers have moved to making block heaters an "optional extra" rather than standard equipment. This allows buyers in warmer climates to avoid paying for a feature they won't use.


Q3: Can I have a block heater installed at the dealership?

A3: Yes. If your vehicle didn't come with one from the factory, our certified technicians can install an OEM Mopar block heater. This ensures a perfect fit and maintains your vehicle's warranty.


Q4: When should I start plugging in my block heater?

A4: It is generally recommended to plug in your vehicle once temperatures drop below -15°C (5°F). Most modern engines only need to be plugged in for 2–3 hours before starting to be effective.


Q5: What happens if I can’t find my cord?

A5: If you aren't sure if your vehicle is equipped or you simply can't find where the cord is tucked, stop by our service bay! Our team will help you locate it or provide a quote for a block heater installation.
