Interchange Part Number : 2344209, 15510Promotions : Magnaflow Catalytic Converter SaleTube Material : Stainless SteelFirst things first: Just like other catalytic converters out there, a Jeep Wrangler catalytic converter isn't repairable. When you're having problems with it, the only solution would be to get a replacement. With that said, detailed below are the common issues that you may encounter with it.
This is the most common problem that you can encounter with your Jeep Wrangler catalytic converter. Your converter may be clogged because the catalyst materials inside it melted or has been contaminated with silicon. Apart from those, there are numerous possible explanations as to why your catalytic converter is clogged, most of which are related to the fuel system.
There are several ways to confirm catalytic converter clogging. First, you can opt to remove the oxygen sensors in your Jeep's exhaust. You see, clogging deprives your vehicle of oxygen. So if your Jeep's performance noticeably dips without the sensors, then your catalytic converter is most definitely clogged. Another way to confirm clogging is by listening for a whistling sound when your accelerator is applied. The whistling is a result of restricted exhaust flow, thus clogging is definitely present if such a sound can be heard. This sound will only grow louder as you drive at higher speeds. A decrease in fuel economy is another telltale sign of clogging. Clogged catalytic converters use up more fuel than normal-you can expect your fuel gauge to drop faster than usual when this is the case. Lastly, your Jeep's engine will generate backpressure because of clogging. That pretty much means that your vehicle won't be running smoothly.
Once you've confirmed the clogging, you better be ready to fork out some cash for a new Jeep Wrangler catalytic converter.
If contaminants don't cause your Jeep Wrangler catalytic converter to be clogged, then they can at least lower the efficiency of your converter. Aside from contaminants, an improper air-fuel mixture due to a faulty oxygen sensor can also affect your converter's efficiency. This issue can at least be fixed by replacing the problematic sensor.
The diminished efficiency of your Jeep Wrangler catalytic converter can be confirmed via an emissions test.
Your Jeep Wrangler catalytic converter isn't the demanding type. You don't necessarily have to keep your converter shiny or whatnot in order to keep it functioning properly. However, you'll want to put a bit of time and effort in taking care of other automotive parts that can affect your converter's function. Detailed below are some of those components as well as additional tips.
Regularly clean your oxygen sensor.
Improper fuel-air mixture can significantly affect the efficiency of your Jeep Wrangler catalytic converter. And there's only one component to blame when that happens-your oxygen sensor. If it isn't in good shape, inaccurate information will be sent to your fuel system, which consequently leads to the incorrect fuel-air ratio. Cleaning your oxygen sensor regularly should prevent most catalytic converter efficiency issues. But if the oxygen sensor is already rusty, you'll have no choice but to get a replacement for it.
Replace any faulty spark plugs.
Your Jeep Wrangler catalytic converter surely wouldn't appreciate a faulty spark plug. It's because a bad spark plug can cause raw fuel to overheat the converter. Overheating should never be underestimated as it can cause total catalytic converter failure. To avoid this major headache, clean your spark plugs from time to time. If they're no longer functioning properly, you'll be left with no alternative but to get new ones. Faulty spark plugs can cause damage to other automotive components other than the catalytic converter (your engine, for instance), thus it's very important to replace them as soon you can.
Drive safely.
Since your Jeep Wrangler catalytic converter is located in a very vulnerable position, driving safely will most definitely go a long way in preserving its good condition. Road bumps and other debris can easily damage your converter if you drive in a careless manner. Yes, it's encased in a hard-wearing shell, but the shell can only take so much punishment before giving out.
Be especially careful when driving with an overheated Jeep Wrangler catalytic converter since it can crack when exposed to ice or snow. It's best to avoid driving in such terrain if you know that your converter has overheating issues.
A warranty that has a free Jeep Wrangler catalytic converter replacement should still be valid regardless if the vehicle is owned by the original buyer or not. As long as the Wrangler is still in its warranty period--usually an 8-year or 80,000-mile period--it should be honored.
If the job is done by an expert mechanic, this could cost almost $300 for both parts and labor. It's best to save some money on labor and study the procedure for a DIY job that will cost around $200 for the replacement part only.
A Jeep Wrangler without a catalytic converter will be noticeable because of the very unpleasant smell coming out of the pipes. If there are any benefits to this, some owners would say that the sound the Jeep Wrangler gives is rougher without it. Also, another tiny bonus would be one device less of the Jeep to worry about. However, the costs greatly outweigh the benefits especially when the biggest consequence would be an increase in exhaust emissions that hurt the environment.
One of the first things that can be noticed is an unusual smell from the exhaust. An erratic shaking or rattling noise from the underside of the Jeep can be heard. There may also be significant power loss every time the accelerator is pressed. By this time, the Jeep Wrangler catalytic converter might have clogged up the system. When doing a repair, check the rest of the exhaust for any clogs, cracks, and other defects caused by the bad catalytic converter. It's best to perform the replacement along with a comprehensive exhaust repair.
