HI, this guide
will help you with this replacement.
Lift your jeep. Unfortunately, the catalytic converter
sits about midway down the length of your jeep, so lifting one end or
the other will not do. Ramps are your best bet to get you within reach
of the parts when working from home. Luckily, this is usually the
hardest part of this repair.
Be patient with the bolts, as they are often hard to remove due to size
and awkward placement. You may have to drill or saw bolts to remove
them. With this in mind, you should pick up new bolts, nuts and seals
for your replacement project.
Buy a catalytic converter specific to your jeep to avoid extra work. A
generic part must be welded into the jeep, while a vehicle-specific
model comes pre-welded to the proper pipes for easy bolt-on
Remove the 02 sensor (with an O2 wrench) before unbolting the catalytic
converter. Then, you should remove the pipe connecting the sensor to
the converter. Depending on your exhaust system, you may have to remove
more pipes before you unbolt the converter from the muffler
Replace the old catalytic converter with a new one. This should be the
easy part, as you simply bolt the new part in place.
Reattach the exhaust pipes
and 02 sensor, and the basic job is done. Make sure you replace any
cracked or rusty pipes while you have the exhaust system apart.
converters often fall under a separate emissions warranty that lasts at
least 7 years and 160,000 miles. Even if your car is out of its regular
warranty, but it is a newer model, ask your dealer to replace the part
for you free of charge.
- Rent the O2 wrench or socket if you do not own one. Most auto parts stores carry this tool for rentals.
many states, older (vintage) cars do not need a catalytic converter, so
you can gut it or remove it completely. No damage will result from
running a car without a converter.
- Due to emissions standards, it is illegal to buy or install used converters.
Please rate and god bless:)
