You can just unbolt this. Just as a word of advise drop the lower control arms when you change the header. And jack the jeep up all the way. This will give you a lot more room to work. It can be a pain to get in and out. I have went through three headers, they keep cracking. I'm going to try and use heat wrap this time. Good luck, don't get discouraged you can do it.

How to replace exhaust donut on 99 wrangler


This is pretty straight forward, you need to locate the exhaust manifold and follow it down to where it connect to the exhaust pipe, there three bolts on the joint and you take those out. Then see if you can separate the pipe from the manifold. If you cannot separate them then you need to get under the jeep and loosen the holders for the exhaust pipe. When you can separate the joint, take the old doughnut out and put in the new one. Make sure that you get it tight and that you tighten the bolts evenly. Don't over tighten one side.

Replaced exhaust manifold on 99 jeep wrangler. turned ignition to start up and engine screams in full throttle, what could be the problem: vacuum, sensor???


The intake manifold is the common culprit for this. It may look like it is flush to the block, but it isnt and is causing a huge vaccum leak. There are two locating dowel pins that the manifold must be flush on before tightning the bolts. The usual problem is that the manifold is resting on top of these pins instead of flush, causing a gap. You have to unbolt the intake and exhaust manifolds, relocate the intake and replace the bolts.

99 jeep cherokee will not stay started if drops to 800rpms. if i keep it reaved to 2000rph for several min and slowly let it out its fine


first items to test would be the mainfold air temp sending unit and the coolant temperature sender. Either can cause a similar condition.I'm assuming that after you do the 2,000rpm thing, it's good 'till it cools down?

How do you change the exhaust manifold on a 93 Jeep Wrangler?


If it's a 4.0 the intake and exhaust both need to be removed. It's a simple unbolt and put back on. make sure you write down and mark any sensor wires and cables, so you can put them back on properly. If you are really unsure of yourself, get a chiltons or haynes manual or have a shop do the work for you. Torque setting on all bolts is 24foot pounds except the first one closest to the front, and the same one closest to the rear which are both 17 lbs.

Replace 1995 jeep wrangler catalytic converter


If it has flanges on both ends, just unbolt it and replace. If it has welded pipes you will need to cut it off and use adapter sleeves and clamps. Really not rocket science...at worst, you may need to remove the hangars on the rear portion of the system to get enough room to install.

Catalytic converter


HI, this guide will help you with this replacement.

Step1 Lift your jeep. Unfortunately, the catalytic convertermag-glass_10x10.gif 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. Step2 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. Step3 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 installation. Step4 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. Step5 Replace the old catalytic converter with a new one. This should be the easy part, as you simply bolt the new part in place. Step6 Reattach the exhaust pipesmag-glass_10x10.gif 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.

  • Catalytic 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.
  • In 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:)

Jeep Wrangler Gas Consumption and Loss Of Power


If its using a lot more fuel than usual its almost garaunteed an 02 Sensor. Those are located on the Exhaust Manifold's, are about the size of your thumb, and generally have 2, or 3 wires coming from them. If you can, check them for operation before you replace them as sometimes they're kindof expensive.
