Jeep 2.4L Specifications:

Now that you know the basic specs of Jeep 2.4 (Jeep Cherokee -KJ 2.4i), let’s look at the associated problems and the fixes.

1. Oil Leakage Issue in Vehicle:

Oil leakage is a common problem for Jeep 2.4L engine owners. The most common cause is a faulty oil cooler, which is responsible for maintaining the temperature of the oil within the vehicle. If the oil cooler is defective, it can cause a leak in the oil chamber of the Jeep 2.4 engine.

In some cases, the engine may be defective from the factory, resulting in oil leakage. This has been the subject of a lawsuit filed by Caren Christman against Fiat Chrysler, alleging that the company failed to provide adequate repair and replacement services for this defect.

Here are some of the common reasons which cause the oil leakage issue in the engine of Jeep 2.4:

1.1. The Issue with Main Sources of Oil Leaks:

Two main sources cause oil leakage in the engine of Jeep 2.4. These sources include:

• The main seal
  
• Gasket of the valve cover

Valve cover gasket is more prone to tearing as they are made of rubber. So, the engine of Jeep 2.4 is more likely to show oil leakages.

How to Fix:

To solve the oil leakage issue due to these problems, you can seek help from a local mechanic or an automobile expert instead of fixing it yourself.

1.2. Lower Oil Pressure:

When the oil pressure is low, the oil may not reach all the engine’s components that need lubrication, such as bearings, pistons, and camshafts. As a result, these components may experience more friction and heat, leading to premature wear and tear.

Low oil pressure can sometimes cause the engine's seals and gaskets to fail, leading to oil leakage. The seals and gaskets in the engine are designed to prevent oil from leaking out of the engine and onto other parts of the vehicle. However, when the oil pressure is low, the seals and gaskets may not be able to maintain a tight seal, leading to oil leakage.

Additionally, low oil pressure can cause the oil pump to work harder than normal, which can cause it to wear out faster.

A worn-out oil pump can result in poor oil circulation and pressure, leading to further engine damage and leakage.

How to Fix:

To fix an oil leakage issue caused by low oil pressure in a Jeep 2.4L engine, the following steps can be taken:

1. Check the oil levels regularly:Check the oil levels in your Jeep’s engine regularly, at least once a month or more frequently if you drive often.
   
2. Check for any visible leaks:Look for any signs of oil leakage, such as oil puddles or stains under the vehicle. If you notice any leaks, identify the source of the leak and fix it promptly.
   
3. Replace worn-out seals and gaskets:If worn-out ones cause oil leakage, replace them immediately.
   
4. Replace the oil pump:Replace it if worn out to ensure proper oil circulation and pressure.
   
5. Use high-quality oil:Use high-quality oil that meets the manufacturer’s specifications and change the oil and oil filter as recommended in the owner’s manual.
   
6. Seek professional help:If you are not confident in diagnosing and fixing the issue, seek professional help from a qualified mechanic.

2. Excessive Consumption of Oil:

If you’re a Jeep owner with a 2.4L Tigershark engine, you may have noticed that your engine is consuming oil at an alarming rate.

Many Jeep owners have reported that their engine consumes a quart of oil every 1,000 miles, which can be frustrating, expensive, and even dangerous.

The 2.4L engine operates quickly and actively in burning up the oil, thus exceeding the normal consumption rate. This can be very troubling for the users, especially when considering oil prices. This is why regular monitoring of the consumption rate and topping off the oil is essential.

One of the biggest concerns with excessive oil consumption is that it can damage the engine if the oil level is not monitored and topped up regularly.

If the oil level drops too low, the engine can seize, resulting in costly repairs.

Another concern is the inconvenience and expense of having to top up the oil frequently. Not only does this consume time and money, but it can also be irritating to monitor the oil level and add oil constantly.

It’s important to note that excessive oil consumption is not normal, and there may be an underlying issue causing it. It could be a problem with the piston rings, valve seals, or PCV system, among other things.

How to Fix:

• STEP 1:The first step to fixing excessive oil consumption is identifying the problem. If you have noticed your oil level has been dropping despite regular oil changes, the problem is likely related to the piston rings. If this is the case, then you must get the piston rings replaced as soon as possible. This will help ensure that your engine runs as efficiently as possible.

• STEP 2:Next, you must check and adjust the oil pressure. This can be done by taking your vehicle to a licensed mechanic or checking the owner’s manual. Ensure that you save all documents that are needed for the repair.

• STEP 3:Finally, keeping up with regular oil changes is essential. The oil-change interval recommended by the owner’s manual is four to six thousand miles, but owners may find that changing the oil after three hundred and fifty miles is advisable.

3. The Issue with the Battery:

There are various issues associated with the battery of Jeep 2.4, which leads to engine issues in the vehicle. Some of the most common causes which lead to battery issues include:

1.1. Leaked Coolant of Battery:

Leaked Coolant or Battery Fluid in the Jeep 2.4 engine is a common issue many Jeep owners face. The engine is designed to operate with a specific amount of coolant.

Therefore, any loss or leakage of the coolant can cause significant problems with engine performance and overall vehicle reliability.

One of the primary reasons for coolant leaks is a faulty radiator or water pump. A damaged or malfunctioning radiator can cause leaks, leading to low coolant levels and overheating. A failed water pump can cause coolant leaks and engine failure.

Another common reason for coolant leakage is a cracked engine block or head gasket. The engine block is the central component of the engine, and a crack in it can cause severe problems, including engine failure.

Leaked battery fluid can also cause significant damage to the engine and other components in the Jeep. Battery fluid leaks can occur due to a cracked battery case or a damaged battery terminal.

If the battery fluid comes into contact with any engine components, it can cause corrosion and damage to the engine, electrical system, and other parts of the vehicle.

1.2. Less Horsepower:

A 1.3-liter four-cylinder turbo engine with direct injection produces 210 lb-ft of torque and 177 horsepower, while a 2.4-liter Tigershark® MultiAir® 2 engine offers 175 lb-ft of torque and 180 horsepower. 

• A clogged air filter is one of the most common reasons for low horsepower. The air filter’s job is to keep dirt and debris from entering the engine, but when it gets dirty, it can restrict airflow to the engine, causing it to work harder and reducing its power output.
  
• Another reason for low horsepower is a malfunctioning Mass Air Flow (MAF) sensor. The MAF sensor calculates the portion of the air entering the engine, and if it’s not working correctly, the engine may not receive enough air, resulting in a loss of power.

1.3. Low Towing Capacity:

Although modern Jeeps are known for their ability to traverse various terrains, the 2.4L engine’s towing capacity can be a significant issue compared to other off-road vehicles.

This is because the torque and horsepower figures of the engine need to be more impressive to handle the task of towing adequately. The result is that the Jeep 2.4L engine will have difficulty towing anything beyond its weight.

How to Fix:

• STEP 1:The first thing to check is the battery’s connections. Ensure they’re clean and tight, as loose or corroded connections can prevent the battery from charging correctly. If you find any corrosion, you can clean it with a wire brush or a battery-cleaning solution.

• STEP 2:Another thing to check is the battery’s age. Most batteries have a 3 to 5 years lifespan, so if your battery is getting old, it may be time to replace it. You can check the battery’s age by looking at the date code on the battery. If the battery is under warranty and still within the warranty period, you can replace it at no cost.

• STEP 3:You can check the alternator if the battery is not the problem. The alternator is responsible for charging the battery while the engine is running, so the battery won’t be charged if it’s not working correctly. In addition, a multimeter can be used to check the alternator’s voltage output. If the alternator is not working, it may need to be replaced.

• STEP 4:Finally, you can check the electrical system for any parasitic drain. A parasitic drain occurs when the battery is constantly drawn, even when the vehicle is turned off. To check for this, disconnect the negative battery terminal and use a multimeter to measure the current flow. If there is a constant flow of current, you can use a process of elimination to identify the component causing the drain.

4. Heavy Fuel Usage by Engine:

Another issue that is quite annoying for the users of the jeep 2.4 is that the vehicle is considered a gas guzzler. Since the vehicle has a 2.4 engine, it can guzzle fuel faster than any other vehicle. Also, when fuel prices increase globally, this problem is a nuisance for several users worldwide.

In addition to heavy fuel usage, the vehicle emits excessive hazardous gases through the tailpipe, as reported by a large group of users all over the globe. In addition, it means the vehicle’s engine gobbles up excessive oil when driven.

On average, it is said that after every 1000 miles, the vehicle guzzles up around one-quarter of engine oil, converts it into carbon dioxide, and releases it into the air through the exhaust pipes, which is hazardous to the environment and human health.

How to Fix:

The fuel injectors are responsible for delivering fuel to the engine. Over time, they can become clogged or dirty, causing the engine to use more fuel. Cleaning or replacing the fuel injectors can help resolve this problem.

So, if you cannot detect engine issues, you can contact the dealership or seek help from an automobile expert dealing the engine 2.4.

5. Transmission Problem:

Many owners have reported issues with their transmission, including difficulty shifting gears, slipping gears, and a jerky or rough ride. These problems can be caused by various factors, from worn-out transmission fluid to faulty sensors or solenoids.

How to Fix:

In some cases, a complete transmission replacement may be necessary to fix the issue. As such, it’s essential to address any transmission problems promptly to prevent further damage to your vehicle.

Regular maintenance, including changing the transmission fluid and filter, can help extend the lifespan of your transmission and prevent future issues.

If you’re experiencing transmission problems with your Jeep 2.4L engine, it’s best to consult with a qualified mechanic who can diagnose and repair the issue efficiently and effectively.

6. Vibrations and Shaking:

One of the most common indicators of an issue with this engine is vibrations and shaking. Vibrations and shaking are usually caused by an overheated engine or driving the vehicle for an extended time.

It’s important to note that various issues can cause vibrations and shake. It could be due to the following:

• Old spark plugs
  
• Worn or broken engine mounts
  
• Internal engine damage

If the vibrations and shaking continue after the engine has been running for a while, this could indicate an issue with the engine’s oil or the cooling system.

If the engine suddenly loses power or the oil pressure drops, this could mean an internal engine issue.

How to Fix:

Replacing spark plugs, repairing or replacing engine mounts, and replacing worn piston rings can solve the issue. Inspecting it by a qualified mechanic as soon as possible is essential.

In addition, regular maintenance of the engine and its parts can help to prevent future problems.
