During the operation of the engine, it produces waste gases that need a way out. The function of a Nissan Patrol exhaust is the same as that of all non-electric vehicles. When it’s properly maintained, it prevents air pollution within and around the vehicle. Plus, it boosts vehicle performance and fuel efficiency, especially in areas with diverse weather conditions.

Now that you have an idea about the importance of proper maintenance, here are some tips on how you can go about it.

1. Book regular inspections

Why they matter:

When you check the exhaust on a regular basis, you can spot leaks, cracks, rust, and other potential issues that can be aggravated by rough terrains and humid coastal conditions.

What to look for:

• Visible signs of damage or corrosion on the metal
• Hissing, rattling, and other noises that weren’t there before
• Abnormal smells that indicate a leak or blockage

When to inspect: It is recommended that you check the system every 10,000 kilometres or during regular maintenance visits.

Clean the exhaust

• Cleaning: Use brushes, polishing pads, and specialised cleaners to get rid of any carbon build-up.
• Flushing:
  • Let it cool down after any off-road adventures, long trips, or typical drives.
  • Wash it with water to remove any rust.
  • Use a heavy-duty degreaser to get rid of rust and carbon.
  • Use steel wool or a brush to remove any collected sediments.
  • Apply metal polish to add a protective layer.
• Clearing:
  • Add recommended exhaust-specific additives to your fuel tank.
  • Shop for a replacement muffler online if facing a severe clog or blockage.

2. Prevent corrosion

How it forms: Rust and corrosion occur due to humidity, moisture, or exposure to road salts from high rainfall or coastal areas.

How to prevent it:

• Use protective covers or park in sheltered areas to reduce the chances of corrosion from forming during the wet season.
• Apply rust-resistant sprays or coatings, especially for vehicles frequenting muddy or wet terrains.

How to deal with it:

• Use a wet steel brush and apply a small amount of pressure to the affected areas.
• Soak some cloth in vinegar and wrap it around the rusted area of the exhaust.
• Dip a scrunched-up ball of aluminium foil in vinegar and scrub the rust from the metal.

3. Deal with leaks

What to look for:

• Is there a strong smell inside or around your vehicle?
• Have you noticed a reduced acceleration level?
• Did you hear any loud noises coming from the engine?

How to fix them: Use sealants as a temporary fix or for small leaks, particularly those who need to drive in remote areas.

When to ask experts: Turn to professionals when the leak can’t be easily repaired, when it affects safety or performance, when it’s extensive, or when you just want to avoid having noisy vehicle exhaust.

4. Buy new exhaust

Sometimes, the damage can be bad enough that you need to replace your current exhaust with a new one. It might also be that your system is outdated or you want to improve the performance of your Nissan Patrol or off-road SUV. If you’re looking for aftermarket options online, make sure to purchase from a reliable supplier like Torqit.
