If your Jeep Commander is having trouble starting, the starter could be the problem. Many drivers want to check or replace their starter but struggle to find its location. Knowing where the starter sits can save you time, money, and frustration. This guide will help you find the starter on a Jeep Commander, explain what it does, and offer tips for safe removal.
What Is A Starter And Why Does Its Location Matter?
The starter is a small but powerful electric motor. When you turn the ignition key, the starter spins your engine to begin the combustion process. Without a working starter, your Commander won’t run at all.
Finding the starter can be tricky because it’s usually placed low on the engine. Its location affects how easy or hard it is to inspect, remove, or replace.
For the Jeep Commander, this knowledge is key, especially if you plan to do the work yourself.
Jeep Commander Starter Location: Quick Overview
Most Jeep Commander models use either a 3.7L V6, 4.7L V8, or 5.7L Hemi V8 engine. The starter location is similar, but there are small differences. Here is a quick comparison:
| Engine Type | Starter Location | Access Point |
|---|---|---|
| 3.7L V6 | Lower rear, passenger side | From underneath |
| 4.7L V8 | Lower rear, passenger side | From underneath |
| 5.7L Hemi V8 | Near oil pan, passenger side | From underneath |
No matter your engine, you’ll find the starter near the transmission bell housing on the passenger side. You will almost always need to access it from under the vehicle.
How To Locate The Starter On A Jeep Commander
- Park Safely: Make sure your Jeep is on a level surface. Set the parking brake and disconnect the battery.
- Lift the Vehicle: Use a jack and secure jack stands. Never crawl under a car supported only by a jack.
- Find the Passenger Side: Go under the vehicle, toward the passenger side, just behind the front wheel.
- Look for the Starter: The starter is a cylindrical component, usually about 6-8 inches long, with a thick wire coming from the battery.
- Check for Obstructions: Some models may have a plastic or metal splash shield. Remove it if needed to get a better view.
- Identify the Mounting Bolts: The starter is attached to the transmission bell housing with two or three bolts.
Here’s a simple visual comparison of how easy it is to access the starter on different engines:
| Engine | Ease of Access | Extra Steps Needed? |
|---|---|---|
| 3.7L V6 | Moderate | Remove splash shield |
| 4.7L V8 | Moderate | Remove splash shield |
| 5.7L Hemi V8 | Hard | Remove shield, may need to disconnect exhaust |
Non-obvious Tips For First-time Diyers
Many guides skip these details, but they can save you a lot of hassle:
- The starter wiring is often tight. Take a photo before disconnecting anything.
- If your Jeep has skid plates or extra shielding, you might need to remove these first.
- On the 5.7L Hemi, the exhaust pipe sometimes blocks the starter. Some owners loosen the exhaust bolts for extra room, but be careful not to damage the exhaust seals.
Step-by-step: Removing The Starter
If you need to take out the starter, follow these steps:
- Disconnect the battery: Always start by removing the negative cable.
- Lift the vehicle: Safely jack up the Jeep and use stands.
- Remove shields or skid plates: Use a socket set to remove any covers blocking access.
- Locate the starter: Find the cylindrical motor on the transmission’s passenger side.
- Disconnect wires: There will be a thick main cable and a smaller signal wire. Label or photograph them before removal.
- Remove mounting bolts: There are usually two or three bolts holding the starter to the bell housing.
- Take out the starter: It may be a tight fit; wiggle gently but do not force it.
Common Mistakes To Avoid
- Not disconnecting the battery can cause shocks or damage electronics.
- Forgetting wire locations makes reinstallation harder. Take photos or label wires.
- Dropping bolts inside the engine bay can cost you time. Use a magnet tool if possible.
- Not checking for other issues: Sometimes a no-start problem is caused by a bad battery, not the starter.
Signs Your Jeep Commander Starter May Be Failing
Look for these warning signals:
- Clicking noise when you turn the key
- No sound at all, but lights work
- Intermittent starting (works sometimes, not others)
- Smoke or burning smell from under the car
If you notice these, check the starter’s connections before replacing the part.
When To Call A Mechanic
While many owners can replace the starter with basic tools, some jobs are harder. If the exhaust or other parts block access, or if you feel unsure, it’s best to call a professional. Incorrect installation can damage your engine or electrical system.
