Jeep J20 Customer Reviews

I'm a little confused!!!! I installed the o2 sensor and I still have the same problem. I might need the air injection pump to complete my mission.

Jeep J20 Guides

The first series of Jeeps made for civilians came out way back in 1945 after they were used extensively during the Second World War. These tough 4x4 vehicles are actually the inspiration for today's sports utility vehicles and other light pickup trucks. The brand has bounced from company to company but it's now currently under the management of the Chrysler Group. Nevertheless, the Jeep brand has kept its tough looks and heavy-duty performance in each and every model that they have come up with. One of these trucks, the Jeep J20, was the precursor of the brand's famous Cherokee and Wagoneer models.

The Jeep J20 was actually first manufactured under American Motors Corporation from 1974 up to 1987. When you take a look at it nowadays, you'll probably see that it looks like a cross between the Jeep J10 and the Jeep Gladiator. It also has the same body styling of the Cherokee down to the conventional slab-sided or step-side cargo box. Actually, the J20 was simply an upgrade J10 and even shared the same front axle, dashboard, and Quadra-Trac four-wheel drive system. Even with these similarities, the J20 still stands out on its own thanks to its powerful engine and unique interior design.

Jeep J20 parts included wooden exterior accents, chrome bumpers, dual horns, 12.5-inch power front disc brakes, and a locking glove box. Under the hood, it was powered by a monstrous 360 cubic-inch V-8 engine. Owners had the option of getting it either with a three-speed manual or a three-speed automatic transmission. When Jeep was bought by the Chrysler Group, the entire J-Series truck line was dropped and was replaced by the Comanche. Its short 13-year run saw it move from a couple of different companies, which could be a problem when getting aftermarket parts. Owners are advised to be wary when getting parts for this vehicle and make sure that it's made specifically for the Jeep J20 model that they have.

How to Care for your Jeep J20’s Exhaust

The Jeep J20 is a full-sized pickup truck that is based on the Jeep Wagoneer platform. It is powered by a huge engine and its design is timeless. This is why pickup truck owners, like you, love the Jeep J20. Its 5.0-liter engine burns a lot of fuel so naturally, however it produces emissions that are potentially harmful to people and the environment. But don't worry, these harmful emissions will be taken care of by the truck's exhaust system.

The exhaust system is responsible for reducing the harmful exhaust gases created during the combustion process in the engine. It also reduces the noise during combustion and ensures that the fuel is burned efficiently. What it does for your truck is very important, that is why it is only fitting that you keep it and its components well maintained. Here are some tips on how to take care of your Jeep J20's exhaust system:

  • Keep the exhaust manifold clean.

The first part of your truck's exhaust system is the exhaust manifold. What it does is it channels the exhaust gases away from the engine to get into the catalytic converter. Since it is the first part of the exhaust, it normally gets very dirty due to carbon buildup coming from the exhaust gases. What you should do is to brush off carbon buildup and other dirt and rust. After scrubbing off dirt and rust, treat the cast iron exhaust manifold with lacquer thinner. Don't forget to inspect it for cracks and dents before mounting it back to the engine. When you mount it, make sure that the holes on the engine and the exhaust manifold are properly aligned to prevent exhaust gases from leaking out. And because it gets too hot in the engine bay, you can apply heat shield on it to protect it from the heat.

  • Ensure that the exhaust pipe is properly attached.

The exhaust pipe is connected to the exhaust manifold. It routes the exhaust gases from the exhaust manifold to the catalytic converter. It is made of iron, so it is prone to rust. Clean it together with the exhaust manifold and make sure that it is attached properly when you put it back.

  • Check the catalytic converter from time to time.

The catalytic converter turns the harmful emissions created during the combustion process into less harmful gases before it is released from the vehicle. It usually does not wear out easily because it doesn't have moving parts in it. Just make sure that it has no dents and its metal housing is free from rust. If it gets hit with a sharp blow, the catalyst material inside the catalytic converter might get damaged, so if that happens, have it checked immediately.

  • Ensure that the muffler is rust-free.

The muffler reduces the noise created during the combustion process. It is located at the rear end of your vehicle. It can get easily damaged due to its location, so make sure that you check it for cracks and that it is free from rust.
