Jeep Wrangler TJ Catalytic Converter
How to Maintain the Jeep Wrangler (TJ) Catalytic Converter
Catalytic converters are often advertised as being maintenance-free, but that is often not the case with the ones in your Jeep Wrangler (TJ). While they do require less maintenance compared to other parts of your vehicle, the Jeep Wrangler (TJ) catalytic converters do need maintenance every now and then. Dirt, fluctuating temperatures and harsh weather, and driving conditions can lead to wear of the cats, but with proper care and usage, they can keep running in excellent condition for many years or even decades to come.
In this guide, we list down some simple ways on how to maintain the Jeep Wrangler (TJ) catalytic converter:
- Wipe dirty catalytic converters with a clean cloth soaked in soapy water.
Catalytic converters can build up dirt pretty quickly, especially if the truck is driven frequently through dusty or muddy terrain. Luckily, most surface dirt, mud, and other debris can easily be removed by wiping the cat with a damp cloth that's soaked in soapy water. Make sure to cover all of the corners and recesses where dirt can accumulate, and rinse thoroughly with water and wipe dry.
- For really tough dirt and stains, soak the catalytic converter in a mix of degreaser and hot water in a bucket.
Allow the catalytic converter to soak for a few hours, and spray it clean. This should allow the degreaser to seep through most of the dirt and make it easier to remove. If the stains are particularly stubborn, you can follow use a power washer to blast off any remaining dirt and grime on the surface.
- Take care of the engine as well.
The cat is highly sensitive to changes in the content and temperature of the exhaust gases, so if there is a problem in the engine or any of its individual components, it would also affect the performance of the catalytic converter. So if you are having engine problems with your truck, make sure to have the catalytic converter checked as well.
- Avoid parking the truck in dry grass and dry leaves.
The catalytic converter can get really hot real fast, and keeping it away from inflammable objects is the best way to avoid accidental fires.
