Chrysler 200 2015-2017 Body & Frame Bolt Torque Specifications

Using the correct torque specification is crucial for several reasons. Over-tightening can damage the bolt, the threads in the body, or deform the component, leading to future failures, noise, and even compromised structural integrity. Under-tightening can lead to loose connections, causing rattling, misalignment, and potentially detachment of body panels or components. Correct torque ensures the designed clamping force is achieved, maintaining the integrity of the vehicle's structure and the security of attached components.

Overtightening a body bolt can lead to several problems. The bolt itself might stretch or yield, losing its clamping strength. More critically, it can damage the threads in the vehicle's body, which may require expensive repairs such as drilling out the bolt and installing a thread repair insert. Overtightening also risks distorting or cracking the panel or component being secured, potentially creating alignment problems or points for rust to develop. Imagine overtightening the bolt holding on a fender - you could easily deform the fender and misalign it with the door or hood.

Under-tightening a body bolt can cause the bolted connection to loosen over time. This can result in rattling, vibrating, and misalignment of body panels. For example, an undertightened bumper bolt could cause the bumper to sag or become misaligned, leading to cosmetic damage or potential safety hazards. If bolts are too loose, they can shear or fall out entirely, posing a risk to other drivers and pedestrians. In short, an undertightened bolt is just as problematic as an overtightened one.

While you can use a regular wrench to tighten body bolts, it is highly recommended to use a torque wrench for accuracy, especially in critical areas. A regular wrench doesn't provide a way to accurately measure the force being applied, making it easy to over or undertighten the bolt. A torque wrench allows you to apply the specified torque which the engineers designed for the body system. This prevents accidental damage, ensures optimal clamping force, and contributes to the longevity and safety of your vehicle. For non-critical fasteners you might be able to get away with an educated guess, but for body bolts where safety and alignment are essential, a torque wrench is a must.

Yes, in addition to a torque wrench, it's often helpful to have a set of sockets, extensions, and possibly a swivel adapter to access all the body bolts. For specific models, a service manual may be needed to identify exact locations and any unusual bolt types. Cleanliness is important; any dirt or debris on the bolt threads will cause an incorrect torque reading. Some bolts, especially those made of aluminum, may have anti-seize or thread locker applied, so inspect your bolts and reapply if required. Always follow any specific instructions in the service manual. It's also important to work on a clean and stable surface to avoid accidental injuries.
