Hack Attack Motor Replacement: How to Replace Your Car’s Motor

As a car owner, one of the most daunting and expensive repairs you can face is a motor replacement. Motors can fail for many reasons, and when they do, getting your car back on the road can be an uphill battle. Not only is the cost of a new motor prohibitive for many people, but the labor involved in replacing it can take days, if not weeks, and result in thousands of dollars in mechanic’s fees.

Fortunately, there are ways to save on the cost of a motor replacement. With a few basic tools and some know-how, you can tackle the job yourself and get your car running smoothly again. This article will guide you through the process of a hack attack motor replacement, from diagnosing the problem to removing and installing the new motor.

What Causes a Motor to Fail?

Before diving into the process of a hack attack motor replacement, it’s important to understand why motors fail in the first place. Here are some common reasons:

Age and Wear and Tear

Over time, the internal components of an engine can wear out or become damaged. Pistons can become bent or broken, the timing belt can snap, gaskets can fail, and so on. These issues may gradually worsen over time until they lead to engine failure.


If an engine becomes too hot, it can cause a variety of problems. For example, the metal parts can warp and lose their shape, or the coolant system can malfunction, leading to a loss of coolant and further overheating. Overheating can also cause damage to the motor’s sensors and electrical components, leading to eventual failure.

Oil Issues

If an engine is low on oil or if the oil is contaminated with dirt or other debris, it can cause damage to the internal components. Lack of oil can cause bearings to seize up, while contaminated oil can cause damage to pistons, cylinders, and other vital parts.

Diagnosing the Problem

The first step in a motor replacement is to figure out what’s wrong with the existing motor. Here are some signs that your motor may be failing:

  • Your engine is making loud, unusual noises
  • Your engine is producing smoke or emitting strange smells
  • Your engine is losing power or running roughly
  • Your engine won’t start or is difficult to start
  • Your engine is consuming oil or coolant at an unusual rate

If you’ve noticed any of these symptoms, it’s likely that there is something wrong with your engine. The next step is to determine what is causing the problem. You can do this by looking for clues under the hood:

  • Check the oil level and condition. If the oil level is low or the oil is visibly contaminated, this could be contributing to the problem.
  • Check for leaks. Look for signs of oil or coolant leaks around the engine. These can be a sign of a failing gasket or other issue.
  • Listen for unusual noises. If you hear clanking, ticking, or knocking sounds coming from the engine, this could indicate internal damage.
  • Check for smoke. If your engine is producing blue smoke, this could mean that oil is burning in the cylinders, while black smoke may indicate a fuel problem.

If you’re not sure what’s causing your engine problems, it’s best to take it to a mechanic for a diagnosis. They can use specialized equipment to pinpoint the issue and recommend a course of action.

Getting Ready for the Motor Replacement

Once you’ve determined that your motor needs replacing, it’s time to get ready for the job. Here are the steps you’ll need to take:

1. Get a Replacement Motor

The first step is to get a new motor that will fit your car. You can either buy a new motor from a dealer or salvage yard, or purchase a used motor online. It’s important to make sure that the motor you choose is compatible with your car’s make, model, and year, as well as any required emissions standards or other regulations.

2. Gather Your Tools

You’ll need a variety of tools to perform a motor replacement, including wrenches, sockets, pliers, screwdrivers, a torque wrench, and a lift or jack stands. You may also need specialized tools depending on the complexity of the job, such as an engine hoist or a breaker bar. Make sure you have all the necessary tools before you start the job.

3. Prepare Your Workspace

You’ll need a clear workspace with plenty of room to maneuver the new motor in and out. If you’re working in a garage, make sure the space is clean and well-lit, and that you have plenty of ventilation for when you’re working with fumes.

4. Disconnect the Battery

Before you start any work on your car, it’s important to disconnect the battery to prevent electrical shock or damage. Locate the battery under the hood and use a wrench to remove the negative cable first, then the positive cable.

Removing the Old Motor

With your workspace prepared and your tools at the ready, it’s time to start removing the old motor. Here are the steps you’ll need to take:

1. Drain the Fluids

Before removing the motor, you’ll need to drain all the fluids from it, including oil, coolant, and any other fluids that may be in the system. This will make it easier to remove the motor and reduce the risk of spillage. Use a drain plug or valve to release the fluids into a container, then dispose of them properly.

2. Disconnect Electrical and Mechanical Connections

With the fluids drained, you’ll need to disconnect any electrical and mechanical connections that are attached to the motor. This could include the engine harness, transmission, exhaust system, and other components that are bolted onto the motor. Use your wrenches, pliers, and screwdrivers to remove any bolts, nuts, or clamps that are holding these connections in place.

3. Remove the Motor Mounts

The motor mounts are the brackets that hold the motor in place. They’re usually attached to the frame or subframe of the car and can be found on either side of the motor. Use your wrenches to remove the bolts that are holding the motor mounts in place, then remove the mounts themselves.

4. Disconnect the Transmission

If your car has a manual transmission, you’ll need to separate it from the motor before removing the motor. Use a socket to remove the bolts that hold the transmission to the motor, then gently pull the transmission away from the motor until it’s free.

5. Remove the Motor

With all the connections and mounts removed, you’re ready to remove the motor from the car. Use your engine hoist or lift to carefully lift the motor away from the car’s frame, then lower it to the ground.

Installing the New Motor

With the old motor out of the way, it’s time to install the new one. Here’s how:

1. Prepare the New Motor

The first step is to prepare the new motor for installation. This may involve installing any necessary sensors or components that were on the old motor, as well as making sure it’s properly lubricated and functional.

2. Lift the New Motor into Place

Once the new motor is ready, you can use your engine hoist or lift to carefully lift it into place. Make sure the motor is properly aligned with the transmission and other components, and that the engine mounts are aligned with the frame or subframe of the car.

3. Reconnect Electrical and Mechanical Connections

With the motor in place, start reconnecting all the electrical and mechanical connections that were disconnected during the removal process. This may include the engine harness, exhaust system, and transmission. Make sure all connections are tight and secure.

4. Install New Motor Mounts

Next, install the new motor mounts onto the frame or subframe of the car. Make sure they are aligned with the engine mounts on the motor and that all bolts are tightened properly.

5. Reconnect the Battery and Test the Motor

With the job almost complete, reconnect the battery by first attaching the positive cable, then the negative cable. Once the battery is connected, turn the key in the ignition to see if the motor starts and runs properly. If everything looks good, let the engine run for a few minutes to ensure that everything is working properly.
