how to fix Ford Explorer Fifth Generation (2011-2019) exhaust leak

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the battery to ensure safety.
• Allow the vehicle to cool completely before starting work.

2. Remove Affected Exhaust Components

• Tools Required: Socket set, ratchet, penetrating oil, torque wrench
• Identify which part of the exhaust system is leaking (manifold, pipe, or muffler).
• If necessary, apply penetrating oil to bolts to prevent stripping.
• Remove the bolts or clamps securing the affected component using the socket set.
• Carefully detach the component from the exhaust system.

3. Inspect and Replace Gaskets or Components

• Tools Required: Gasket scraper, cleaning cloth, silicone gasket maker (if needed)
• Inspect the exhaust gaskets for damage; if they are worn or broken, replace them.
• Clean the mating surfaces of the exhaust parts using a gasket scraper and cleaning cloth.
• If the exhaust component is damaged, replace it with a new part.

4. Reinstall Components

• Align the new or repaired component in place.
• Hand-tighten bolts or clamps, ensuring proper alignment.
• Use a torque wrench to tighten bolts to the manufacturer’s specifications (typically around 18-25 lb-ft for exhaust bolts).
• Reattach the exhaust system securely.

5. Final Checks

• Reconnect the battery.
• Start the engine and listen for any leaks or unusual noises.
• Inspect joints and connections visually while the engine is running for any signs of exhaust smoke or noise.
