The cylinder 5 location on a 2007 Jeep Liberty is the rear-most cylinder on the driver’s side (left) bank of the 3.7-liter V6 engine.
Engine layout and cylinder numbering
The Liberty’s 2007 model uses a 3.7L V6 with two banks of three cylinders. For cylinder numbering, each bank is numbered front to back: left (driver’s) bank carries 1, 3, 5; right (passenger) bank carries 2, 4, 6. Therefore, cylinder 5 sits at the back on the left bank, closest to the firewall. If you’re standing in front of the car, the left bank is on your left when looking at the engine from the front. Always confirm the exact layout in your service manual or under-hood diagram, as there can be minor year-to-year variations.
To estimate location, it helps to know where the spark plugs and ignition coils sit on each bank. Each cylinder typically has a spark plug well with a coil-on-plug near the valve cover; cylinder 5’s coil is on the left bank’s rear section.
Be mindful that some variants may use different coil arrangements; consult the factory diagram if you’re planning a plug replacement to avoid confusion.
Where to look in the engine bay
Before you search around, this map helps orient you to the cylinder's position and how to identify it at a glance.
Before the list: Identify bank orientation and cylinder counting to locate cylinder 5 accurately.
- The left bank is on the driver's side of the vehicle when viewed from the front.
- The rear-most cylinder on that bank is cylinder 5;
- Each cylinder has a spark plug well with a coil-on-plug nearby on the valve cover.
Before the list: Identify the left (driver’s) bank, which houses cylinders 1, 3, and 5 from front to rear.
In short, cylinder 5 is the rear-most cylinder on the driver’s side bank of the 3.7L V6. The exact plug/coil routing can vary slightly by model revision, so check your vehicle’s diagram if you’re planning a plug change.
What you should know before maintenance
Always ensure the engine is cool, disconnect the battery if you’ll be removing any wiring, and use proper safety equipment. The left-rear area where cylinder 5 sits may be close to other components, so plan your tool access accordingly.
Summary
For a 2007 Jeep Liberty, cylinder 5 is the rear-most cylinder on the driver’s side left bank of the 3.7L V6, located near the firewall. Identification comes from understanding the front-to-back numbering on each bank and using the spark plug wells and coils as visual cues. When in doubt, consult the factory diagram or a service manual for exact plug locations and torque specs.
