The Four Most Important Parts of Your Jeep

March 15th, 2015 by


Jeeps are rather durable considering all of accompanying capabilities. If you took any other vehicle on the same type of off-roading journeys, you’d be facing a costly repair bill. With the rugged Jeep, you don’t have to worry about those types of issues.

Of course, despite the dependability of the brand, you’re still going to run into issues with your Jeep, just like you would with any vehicle. When these problems arise, you may have difficulty identifying the specific, responsible part. Take a look under your Jeep, and you’ll find an assortment of metal. This can be overwhelming for even the most experienced mechanic or dealership.

Therefore, it’s important that you get a basic understanding of the most important parts of your Jeep. Take a look at our guide below, and you should subsequently be better suited to have an educated conversation with your Jeep dealership in Miami

Catalytic Converter


You’ve probably heard of this part, but we’d bet that many Jeep drivers aren’t aware of how important the catalytic converter actually is. The system essentially takes all of the toxic pollutants the found in exhaust gas and converts them to less-toxic pollutants. To achieve this, the converter must catalyze a redox reduction, the process is complete once the harmful toxins have been eliminated.

When the U.S. Environmental Protection Agency established stronger regulation on exhaust emissions during the 1970s, catalytic converters started becoming standard in many vehicles. Originally, the system took oxygen, carbon monoxide and unburned hydrocarbons, producing carbon dioxide and water instead. The catalytic converter’s inability to work with lead also led to the popularity of unleaded gasoline.

As describes, Jeeps rely on their vehicles’ ability to drive off the beaten path, and they wouldn’t do anything to compromise the environment and habitats. With the brand’s engineers unveiling bigger and more powerful engines, Jeep has done everything in their power to reduce these bad emissions.

It’s essential to check up on your converted (as well as any other essential parts) following any off-roading expedition. Since the part sits underneath your vehicle, there’s a chance that it could be damage by any random obstacles (rocks being the most likely). If the part is damaged, you can expect “a lot of noise,” as well as reduced performance from your Jeep.

As the website describes, if a Jeep’s catalytic converter isn’t working properly, it can realistically be replaced with a “high-flow unit.” The replacement system is designed to be “less restrictive, to decrease backpressure and maximize the vehicle’s gas mileage and performance.”

A/C Compressor


As describes, Jeeps weren’t always equipped with air conditioning units. In fact, it took some time before the brand starting adding the system to their vehicles, finally providing comfort to their thousands and thousands of customers. Of course, you wouldn’t receive this cool air if it wasn’t for the A/C compressor.

The compressor is a pump that’s attached to the Jeep’s engine via a belt. The system is responsible for sending refrigerant through a “closed loop” in the system, all while taking in the accumulated hot air. The refrigerant is “compressed and converted into high-pressure gas,” and that’s eventually sent into your cabin once it has been cooled.

As the website notes, the part is referred to as the “heart of the auto air conditioning system.” The air conditioner controls the temperature inside of your Jeep, circulating a fluid that absorbs heat (known as a refrigerant) via the vehicle’s evaporator. While the warm air is pushed out of the vehicle, the cooler air is sent through the condenser, thus providing comfort to the driver. None of this would happen if the refrigerant wasn’t circulating in the first place, and that only helps with help from the compressor.

Without the A/C compressor, your Jeep will resemble a model from back in the day. The driver’s comfort will be compromised, as there won’t be any cool air being pumped into the cabin. Plus, the hot air sits inside the vehicle, making your ride hotter and unbearable. For your own well-being, it’s a good idea to get this part repaired immediately.



A Jeep’s battery gets all the attention, and it’s well-deserved. The box powers everything in your vehicle, including the lights and radio. Without the battery, you’d be left with a pretty cool driveway decoration, but not much else. The battery helps the vehicle operate, and it the Jeep would practically be worthless (well, not really) without it.

Considering how important the battery is, that makes the alternator even more essential. The battery relies on the alternator to work, as the “electromechanical device…converts the mechanical energy produced by the vehicle’s engine into electrical energy.” The various electronics throughout the vehicle, including the battery, vicariously use this electrical energy to operate.

There are four major parts of an alternator: the stator (helps generate alternating current), a rotor (a magnet found inside of the stator), a voltage regulator (helps “regulate the voltage level of the current flowing to the electrical system) and diode packs (converts the alternating current into direct current).

If your alternator is broken, you’re going to have a tough time operating your Jeep. The battery won’t last nearly half as long as usual, and you’ll find many of the vehicle’s electric components struggling. Of course, as the website notes, it’s difficult to determine whether the part is struggling or not. If you have any doubts, get your Jeep and its mechanics checked by a mechanic as soon as possible.



When an engine starts to heat up, regardless of the vehicle, you’ll find reduced performance from your ride. If this is the case, there’s a good chance that the problem could be attributed to a faulty radiator, as the part is responsible for monitoring the motor’s temperature.

In a Jeep, the radiator is the sole way to cool down an engine. Engines naturally produce heat, and without a source to maintain a safe temperature, the system would be compromised immediately. The radiator takes all of the hot coolant and pushes it through the “cool metal great of the auto radiator,” resulting in a “large amount of heat… dissipat[ing] quickly.”

Overheating engines is actually relatively common in Jeeps, especially the Cherokees. These engines generally warm up quicker than others, making the radiator even more essential.

If your temperature gauge seems to be climbing, that could be an indication that something is wrong. That’s why it’s important to get your Jeep’s radiator serviced at least every two years, assuring that the system is working properly. Furthermore, you’ll want to be sure that the vehicle’s other cooling system components (water pump, auto radiator hoses, and fan belts) are also operating to their full potential. Finally, make sure you flush the system every year, as it will keep the radiator working, helping you avoid pricey repairs.

It’s interesting how interconnected the entire system is, and one minor issue could throw your entire system out of whack. Whenever you start hearing an odd noise coming from your Jeep’s engine or mechanics, you should now have a better understanding of where the problem originates.


Of course, whenever you have an issue with your Jeep, it’s a good idea to visit your local repair shop or dealership. Their knowledgeable mechanics will get your Jeep working good as new!
