Problem Statement

Learn how to check for exhaust leaks on Ford Explorer Sixth Generation (2020-present). Step-by-step guide with diagnostic procedures and repair instructions.

Affected Component

Exhaust System

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow engine to cool before opening the exhaust system.

Symptoms

•Increased engine noise, especially during acceleration
•Unusual odors (e.g., exhaust fumes inside the cabin)
•Decreased fuel efficiency
•Engine performance issues, such as loss of power
•Check engine light illuminated (may indicate related codes)

Diagnostic Steps

1
Examine the exhaust system visually for any visible cracks, holes, or rust, particularly at joints and welds.
2
Start the engine and listen for hissing or popping sounds near the exhaust system, which can indicate a leak.
3
Introduce smoke into the exhaust system using a smoke machine; observe for escaping smoke, which indicates a leak.
4
Inspect the gaskets at the manifold and between sections of the exhaust for signs of wear or damage.
5
With the engine running, pass a propane torch (unlit) around suspected leak areas; changes in engine RPM can indicate a leak.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

Solution

1. Preparation

Gather Tools: Ensure you have the necessary tools including socket set, torque wrench, exhaust gasket scraper, and safety goggles.
Safety Precautions: Disconnect the battery to prevent any electrical issues. Allow the engine to cool before starting the repair.

2. Identify and Remove the Damaged Component

Locate the Leak: Based on the diagnostic steps, confirm where the leak is occurring.
Remove Necessary Components: If the leak is at a joint or flange, remove any bolts or clamps securing the affected exhaust section using a socket set.
Tools Required: Socket set, torque wrench.

3. Clean and Inspect

Clean the Area: Scrape off old gaskets and debris from the surfaces where repairs will be made using a gasket scraper.
Inspect for Damage: Examine the exhaust pipe and surrounding components for any additional damage that may need to be addressed.

4. Replace Gaskets or Sections

Install New Gaskets: If gaskets are damaged, replace them with new OEM or quality aftermarket gaskets.
Reassemble: Reattach the exhaust components, tightening bolts to the manufacturer's specified torque settings.
Tools Required: Torque wrench for correct specifications.

5. Final Check

Reattach Components: Ensure all components are securely reattached and that there are no loose parts.
Reconnect Battery: Once repairs are complete, reconnect the battery.
