Factors Contributing the Replacement Cost for Jeep Grand Cherokee Engine:

Here we will discuss some factors that help get an estimated replacement cost for the engine of the Jeep Grand Cherokee:

  • Cost of labor
  • Engine’s condition
  • Engine’s type
  • Age of the Engine

1. Cost of Labor:

Labor cost is the first factor influencing the cost of replacing an engine. The price of labor varies depending on the engine's condition and the engine type and can even range from $2500 to $3500 in some cases. If the engine is in poor condition, the labor cost can also be higher than the cost of the new engine.

However, it is possible to save on labor costs by attempting to do some work yourself (DIY). If you’re comfortable performing routine maintenance and tinkering with Jeep, you can remove and replace the engine on your own. Doing this can help you save on labor costs and put the money towards a better engine.

2. Engine’s Condition:

The condition of the engine is an essential factor to consider. The cost can be relatively low if the engine is in good condition. However, replacing such an engine can cost extra money if the engine is in bad shape.

If the engine is overused and not maintained correctly, the driver may notice overheating, smoke from the engine, broken pistons, and irreparable engine parts. The replacement cost is higher in such cases because the mechanic has to put extra effort into removing the engine, and costs double the amount.

3. Engine’s Type:

The type of engine is a significant factor in determining the replacement cost. There are different models and types of engines, with each one charging differently depending on its type and category.

A 3.6L Pentastar V6 engine costs $2500, while a 5.7L HEMI V8 engine can cost between $4000 and $6000. If you include the labor cost of the engine, it will charge about $8000. So, it is better to check the engine type before replacing it.

The make and model of the Jeep Grand Cherokee also affect the replacement cost. Different makes and models have different engine sizes, so you should research the make and model to determine the replacement cost.

4. Age of the Engine: 

The age of the engine is another factor to consider when calculating the replacement cost for a Jeep Grand Cherokee engine. If the engine is relatively new, it will cost less to replace than if it is older. 

Additionally, if the engine has a lot of mileage, the parts and labor associated with replacing the engine will also be more expensive.

Reading Jeep Grand Cherokee Engine Codes for Replacement:

When you need to replace an engine in your Jeep Grand Cherokee, the first step is to access the onboard diagnostics (OBD-II) scanner to check the engine fault codes.

This device plugs into an outlet on the driver’s side of the Jeep and helps you easily identify what needs to be replaced.

Jeep Grand Cherokee Engine Replacement Cost and Details

Before using the OBD-II scanner to diagnose your engine, you must ensure it is pre-programmed. Otherwise, when you plug it in, you will see the word ‘scanner’ on display instead of a request.

Depending on the type of scanner you are using, you might need to navigate through various menus and select the correct options before requesting a diagnostic. Therefore, reading the instructions with your scanner carefully is essential to ensure you are using it correctly.

When Should You Change the Engine of the Jeep Grand Cherokee?

When a Jeep Grand Cherokee’s engine gets broken, several symptoms and indicators will show up, making it clear to the user that they now need to replace the complete engine of their Jeep Grand Cherokee.

1. Abnormal Noise:

When the Grand Cherokee Jeep engine comes on the verge of a breakdown or failure, the jeep produces abnormal knocking sounds from beneath the engine. This would come out because the engine bearings would seize due to less lubrication of the engine oil for different parts.

The engine oil is responsible for lubricating certain engine parts, such as the crankshafts, or the engine bearings, which would finally cause the engine to break down. In such a case, the lower half of the engine needs to be replaced because the engine bearings and the engine oil run in the lower portion of the engine.

2. Dense Smoke from Exhaust:

When your Jeep Grand Cherokee begins to produce dense smoke from its exhaust pipe, it clearly indicates that you should change its engine. The smoke you observe will depend on what is wrong with the engine. 

  • White smoke often indicates a coolant leak, which can cause the engine to overheat. 
  • Blue smoke indicates an oil leak, which affects the lubrication of the engine components and causes them to wear out faster. 
  • Black smoke indicates that your Jeep Grand Cherokee is consuming too much gasoline. 

If you observe any of these colors of thick smoke coming out of your Jeep Grand Cherokee, it is time to take it to a qualified mechanic and has the engine replaced. 

You cannot do engine replacement yourself, so be sure to find a qualified mechanic experienced with Jeep Grand Cherokees. In addition to replacing the engine, the mechanic should also check the condition of other components to ensure they are in good working order.

It is best to replace the engine of your Jeep Grand Cherokee as soon as possible when you observe any of the telltale signs of engine trouble.

Doing so will help you avoid further damage to the engine and other parts and help to ensure that your Jeep Grand Cherokee continues to serve you faithfully for many years to come.

3. Reduced Performance:

The most common sign that your engine needs to be changed is a decrease in performance. If you notice a reduction in power, acceleration, or fuel-efficiency, you should take your vehicle to a mechanic and have it inspected.

The mechanic will examine the engine and check for any signs of wear and tear. If the engine is beginning to fail, it may be time to change it.

Another sign that your engine may need to be changed is if the Jeep is having difficulty starting. If the engine cannot start easily, or even at all, then it may be time to replace it. In some cases, the engine may be able to start, but then it may shut off shortly afterward. This is a sign that an engine is beginning to fail.

Finally, if your Jeep has a rough engine idle or difficulty getting up to speed, this could indicate that the engine requires repair or replacement. Having a mechanic inspect the engine and check for any signs of wear and tear is also a good idea.

4. Excessive Consumption of Gas:

If the vehicle becomes a gas guzzler, and the gas consumption does not get settled after regular tuning, the engine has grown weak. It should be repaired, and if repairs cannot be done, it should ultimately be replaced.

These were some of the indicators. If these symptoms come up, it would become evident to the user that the vehicle’s engine has now grown old and should be replaced.

Steps for Replacing the Engine of a Jeep Grand Cherokee:

STEP 1: Engine Isolation:

The vehicle’s engine should be isolated completely when it comes to replacing the engine. Following are the steps which should be followed while isolating the engine for a replacement.

  • The hood of the vehicle should be removed
  • The bumpers, headlights, and other removable body parts should be removed
  • Air manifolds and air boxes should be removed
  • The battery should be removed, and all the electrical wiring should be removed
  • The radiator and the oil chamber should be drained completely
  • The exhaust should be unplugged and removed

STEP 2: Engine Mounts Removal:

The engine mounts are the components that hold the vehicle’s engine in its place. Therefore, when the vehicle’s engine is to be replaced, the essential step is to remove the engine mounts so that the old engine can be pulled out easily.

The engine of the Jeep is connected to the chassis via two mounts located beneath the radiator and behind the engine, respectively.

Therefore, the Jeep must be jacked up and placed on jack stands to remove the engine.

To ensure no surprises, the transmission fluid should be drained before the base drive shaft is disconnected. Then, the mounts securing the engine to the chassis can be unscrewed. An issue could cause this with the fuel delivery system or a blocked air filter, which can be fixed easily.

STEP 3: Hauling the Old Engine:

Once the engine mounts and other parts are disconnected, removing the old engine from the vehicle becomes relatively easy.

Secure the engine to the crane with an additional strap and two steel chains at the gearbox. Once in place, the crane pulls it up. As the engine is raised, check for any attached parts.

For the new engine, obtain components from the old engine. Prior to connecting the new part, make sure to clean and oil the parts from the older model.

STEP 4: Installing New Engine:

Gently lower the new engine into the Jeep Grand Cherokee using a crane. Reverse the steps of the disassembly process, making sure all bolts are securely tightened. Refill any emptied fluids and place the hood and bumper back on the Jeep.

Congratulations – turn the ignition to start the engine and enjoy the result of your tiring work!
