Factors contributing to the replacement cost of Jeep engine

These factors majorly contribute to the replacement cost of the Jeep engine.

1. Engine type

Different brand options like Titan, Dalmer, Tri Star, and others are available for Jeep. Therefore, it depends on which manufacturer you choose, as they vary significantly in price. Moreover, you must know your driving needs while choosing an engine, as different brands offer different specifications, performance variations, and driving abilities.

You can simply go for as low as $2,500 if you are not an off-roader. In contrast, being an off-roader, the most affordable engine you will get is in nothing less than $4,000.

2. Labor cost

Replacing the engine is a lot of time and energy-consuming work. Due to this, labor cost contributes a significant share of the total replacement cost. Even a drop-in fit engine requires many days of disassembly and reassembly. 

As most of the workshops charge per hourly rate, therefore, generally, the minimum labor cost by the end of engine replacement lies between $1000 to $2000. 

Moreover, the engine’s condition is a sub-factor that plays a role in labor cost. If the old engine is in bad condition, it will take more time to disassemble, directly affecting the labor cost.

3. Time

Engine replacement is a complex job, and we strongly advise you to plan this activity with your mechanic before taking your Jeep to the workshop. Decide what engine type to use and what other parts are needed in the replacement, as once the engine goes into disassembly, every passing minute will count in labor time. Eventually, your labor cost will increase. 

4. Age of engine

In other words, the engine’s condition is another factor contributing  to the total replacement cost. As the engine grows, older parts like pistons, crankshafts, bearings, etc., take more time to remove due to rust or other issues. Ultimately, labor cost increases.

5. Engine parts

Several after-market options are available when buying engine parts if you are going for a low-cost changeover. But if you prefer to purchase parts from an OEM, you eventually have to pay more due to their fine quality and brand name. Therefore, it totally depends upon your choice and budget.

Steps to follow while replacing the Jeep Wrangler engine

Follow these instructions step by step to replace your Jeep engine:

1. Disconnect the battery

First, you must disconnect the Jeep battery before starting the process. Also, the whole process will become a lot easier if you remove your bonnet.

Now unplug the negative and positive terminals of the battery.

2. Spill out the fluids.

Spread some rags on the floor before doing this step, as no matter how cautious you are, some of the fluids will mess up the ground. After that, drain out engine oil and coolant on the drip trays cautiously so that you can refill them later if they are in good condition.

3. Remove FRP parts and other accessories.

Take out the bumper, headlights, and other removable body parts, as they will obstruct working. 

4. Unplug the intake, exhaust, coolant lines, and radiator.

Unbolt the intake and exhaust pipes. Also, detach the coolant system and take out the radiator. If you don’t attempt these activities before engine removal, then it will be hanging at the time of taking out the engine.

So, it is better to plan these activities before.

5. Remove the old engine.

Once you have disconnected all the wiring and other electrical equipment, it is time to pull out the old engine. Tie the crane straps to the engine and use steel chains to secure the gearbox. Pull out the engine very carefully now. 

After this, clean all the components, specifically oil parts, to make everything neat before the new engine installation.

6. Install the new engine.

Using a crane, drop in the new engine and fit all the accessories that we removed previously. Reconnect all the electrical wiring, exhaust, intake boxes, radiator, and other similar things.

Now retighten all the bolts and attach the bonnet and headlights. After doing this, refill the coolant and engine oil as needed.

Voila! You are ready to fire your new engine.
