Jeep Wrangler YJ Catalytic Converter

Stretch the Lifespan of Your Jeep Wrangler (YJ) Catalytic Converter with These Tips

You can quickly tell if your Jeep Wrangler (YJ) catalytic converter has gone bad—there's either a dark smoke or a foul smell coming from your vehicle's exhaust system. You need to keep your cat con in proper working condition, as this component sifts the harmful chemicals produced by your engine during combustion. Some states even apprehend those who are driving with faulty cat cons. To have a longer service lifespan, the cat con must be maintained through these tips:

  • Keep track of your catalytic converter's condition.

Despite the fact that the cat con can last as long as your vehicle's lifespan, it can still get worn faster due to various contaminants that settle in it. So make sure that you perform a periodic catalytic converter inspection to prevent minor problems from turning into a more serious, expensive damage. Keep an eye out for tailpipe smoke, loud noise coming from the exhaust, and poor fuel mileage. These can indicate that your cat con has become busted. If you experience such symptoms, then it's probably time to bring your car to an expert mechanic. Repairing or replacing the catalytic converter prevents further damage to your car's exhaust system.

  • Use soap and water to eliminate metallic gunk.

One quick way to maintain your cat con's good shape is to clean it using detergent soap and water. If this doesn't solve the problem, then try using a stronger solution such as lacquer thinner. This can eliminate contaminants like phosphorus and zinc pollutants. Just be sure that you dry the cat con thoroughly as the remaining soap residue can affect its active surface.

  • Lower excessive emissions with a safe cleaner.

A variety of fuel additives are safe and strong enough to use on your Jeep Wrangler (YJ) catalytic converter. In fact, these cleaners even help lower the amount of unburned hydrocarbons left in your vehicle's cat con. However, the fuel additives can only prevent clogs in the cat con. They can't revive a busted unit. Replace your cat con once you verify that it's already irreparable.

  • Spot a Bad Jeep Wrangler (YJ) Catalytic Converter with the Help of These Signs

    When your vehicle's cat con has gone bad, it won't take long before the signs start showing up. It can be in the form of dark smoke or a foul smell, but surely when this happens, you need to get under your car and check on it. Despite the average cat con lifespan of about 100,000 miles, some cat cons break down faster due to a lot of factors such as fuel quality and road debris. To help you know if it's about time to replace your catalytic converter, here are three symptoms you must look out for:

    Your car's performance drops all of a sudden.

    Due to its incapacity to neutralize the harmful chemicals produced during fuel combustion, a damaged cat con may affect your car's overall performance. This results in back pressure, which handicaps the engine's operation. Fixing this trouble immediately is a must, otherwise you are bound to deal with a stalling engine. When this happens, you'll notice your car jerk—something similar to the feeling you get when you step on the accelerator while your vehicle is running on low fuel. It takes an expert mechanic to examine the cat con and find out where the clog has built up. One thing you can do is to remove the O2 sensor from the exhaust pipe and see if there would be a change in your car's performance.

    There's dark smoke coming out of the exhaust system.

    One sure-fire way to tell if your cat con has become spent is to examine the smoke coming out of your car's muffler. If you see that the smoke seems to be dark or almost black while the vehicle is running, then there's a huge chance that your catalytic converter has accumulated contaminants that are clogging it. When the cat con gets clogged, it's usually caused by a considerable amount of carbon buildup inside the converter. But it can also be a result of a damage on the cat con's active surface, leading to a rise in the vehicle's carbon emission levels.

    There's a foul odor coming from the exhaust.

    You don't need expert tools to verify early signs of a faulty cat con. Simply use your nose to check if the cat con is producing a stench that's similar to a combination of sulfur and rotten eggs. When the cat con is damaged, it's nearly impossible not to notice the bad odor it releases, making it a must to replace the component as soon as possible.
