Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Visual Inspection and Access

Tools Required: Flashlight, jack stands, and ramps.
Raise the vehicle using ramps or a jack and secure with jack stands.
Inspect the exhaust system from the engine to the tailpipe, looking for cracks, dents, or rust.

3. Repair Leaks

Tools Required: Socket set, wrenches, exhaust sealant or tape, replacement gaskets.
Tighten any loose bolts or connections in the exhaust system.
If you find cracks, use exhaust sealant to seal minor leaks or replace sections of the pipe if necessary.
Replace damaged gaskets at joints to ensure a proper seal.

4. Reassemble and Test

Reattach any components removed during inspection and ensure all bolts are torqued to manufacturer specifications.
Tools Required: Torque wrench (set to manufacturer specifications).
Reconnect the battery and start the vehicle to test for leaks again.
