Tips to Maintain the Nissan Pathfinder Catalytic Converter in Good Condition
The Nissan Pathfinder bears the power of a utility truck and the creature comfort of a large car. You have to drive this Nissan sports utility vehicle to fully enjoy its features. However, for the very green eco supporters, performance and comfort should not be the only selling point of vehicles being put in the market today. They want reduced emissions just to name one. Leaving smaller carbon footprints has been a factor in more modern auto designs. One component meant to improve your SUV's carbon footprint is the Nissan Pathfinder catalytic converter. It sorts out the engine emission so that it comes out less intoxicating to the environment. To ensure that this part works without any issues, here are some maintenance tips for your Nissan Pathfinder catalytic converter.
- Avoid using silicone products on your exhaust piping.
Avoid using silicone products to mend together pipes in your exhaust system at all costs! While silicone sealants can work for leak-proofing other components, using it on parts that get too hot is a bad idea. The high temperature will cook up the silicone. The fumes will cause inaccurate O2 sensor readings and therefore trigger wrong ECU adjustments. Use the right products to avoid sensor mishaps. This will go a long way.
- Drive carefully on the road and avoid hazards at all costs.
The key here is safe and preventive driving. While we can establish that the Nissan Pathfinder has enough ground clearance to stay away from usual road hazards. But there are other culprits. In case you get a little more adventurous and hit the trail, observe extra caution. Boulders, bushes, and other obstacles on the trail can hit the catalytic converter mounted under your chassis. The best way to avoid damages on the catalytic converter is by steering around these hazards.
- Watch out for engine issues that can affect the catalytic converter.
Since the catalytic converter is routed from your engine, you should keep an eye for engine issues. If engine problems bring in oil or coolant into the combustion chamber, it can hurt your catalytic converter. Keep your engine healthy.
How to Troubleshoot the Nissan Pathfinder Catalytic Converter
The Nissan Pathfinder catalytic converter gets the green thumb up from environmentalists. Having been integrated into vehicles since the mid ‘70s, this component somehow filters and converts the engine emissions into less harmful fumes. But as you use your SUV, this part will eventually wear out. You should expect an average lifespan of 100,000 miles under normal circumstances. After that, it is possible that your catalytic converter begins to fail you. But this failure can also arrive prematurely. If you feel that there is something weird with your fume and performance, then there might be an issue with that part. Here are some tips on how to troubleshoot the Nissan Pathfinder catalytic converter.
Tip #1: Drive your Nissan Pathfinder and try to feel if there is a loss of power and change in fuel economy.
While the loss in power is not a direct result of a faulty catalytic converter, the part reacts negatively with such changes. The loss in power caused by incomplete combustion inside the engine block creates high levels of hydrocarbons which is harmful to the catalytic converter. If this persists, your catalytic converter will get clogged. This restricts the proper breathing of your Nissan Pathfinder. Aside from the loss in power, you will also note darker exhaust smoke. Remedy may involve a change of fuel injectors and fuel pressure test.
Tip #2: Observe your exhaust pipe. Does it emit blue smoke?
The blue smoke coming from your exhaust pipe is a sign that oil is burning inside the engine block. And as the oil fume mixes with the exhaust gas, they pass through and damage the catalytic converter. Proper engine maintenance can prevent this from happening.
Tip #3: Plug in your On-Board Diagnostic analyzer and spot the issue.
More modern cars are equipped with On-Board Diagnostic systems. This regulates and monitors the different functions of your vehicle. This can also be used to pinpoint issues that concern your catalytic converter.
Tip #4: Expect the catalytic converter to last you for about 100,000 miles.
The average lifespan of the catalytic converter is about 100,000 miles depending on your use and degree of maintenance. Once you passed this mark, you should be on the lookout for changes in your vehicle's performance. By this time, you should also be ready to replace the part.
Frequently Asked Questions
A recently bought Pathfinder is already having problems with the catalytic converter. The truck has just been used for more or less 65 thousand miles. Is it still covered by the warranty that Nissan offers?
Nissan offers an 80-thousand-mile warranty for its car models' catalytic converters. If the truck has covered only 65 thousand miles, the cat con damage can still be fixed under the dealership's warranty. Just bring the vehicle to a Nissan dealership right away and have the cat checked by an authorized personnel. You can also call the seller's hotline and explain the situation. Until the car performance test is finished, avoid tampering any component, especially the parts of the exhaust system, which includes the converter. If the damage is caused by the car owner's mistake, warranty will be voided.
Is it possible to replace only the catalytic converter in a Nissan Pathfinder, without removing the other components of the exhaust system? What is the quickest way to do this?
Yes. Simply raise the car to gain access to the cat con, which is located under the vehicle, just underneath the driver's feet. Use a wrench to disconnect the rear edge of the converter from the exhaust pipe. Remove the three mounting bolts to release the old cat, and then install the new one.
What are the obvious signs of Nissan Pathfinder catalytic converter problems?
Because a car's system is so complex, it is sometimes very difficult to pinpoint the cause of certain malfunctions and abnormalities. However, there are indications that clearly points to a failing catalytic converter. First is constant high temperature readings. This temperature measurement is often seen printed on the dash. Extreme heat comes from the excessive amount of unburned fuel in the cat con. This will eventually lead to engine overheat. That explains why the vehicle keeps on stalling or losing power in the middle of the road. Second sign is a red and orange glow seen at the back of the car, just below the tail pipe. Once neglected, a damaged converter can ruin even the whole exhaust system. Third is a horrible smell that comes out of the exhaust pipe. Some people compare it to the stench of a rotten egg. This is due to harmful gases that a bad cat couldn't neutralize before their emission from the tail pipe. These are some of the telltale signs of a damaged cat.
