Can You Put a Truck Engine in a Car?

Not all truck engines can fit in the cars; only diesel engines have this quality. Mostly truck engines are huge compared to the body of a car; that is why the placement is difficult.

Before going into the details, let me explain the tools for this procedure.

Tools required

  • Set of screwdrivers. The screwdrivers must have flat heads. Philips screwdrivers.
  • Rubber gloves
  • Wrenches of various size
  • C-clamps or a wire which should be sturdy
  • A hammer of medium size
  • Rubber mallet
  • Battery(it should belong to you)
  • A-frame to pull engine outside.
  • Lifting Jack
  • Few bolts
  • Protective goggles
  • Fuel gallon
  • Battery
  • Extra screws and bolts
  • Manuals
  • Ignition key
  • Chain or pulling frame

Truck and car should have the same engine power

If you are planning for an engine swap between a pickup and a car, choose the same power equipment.

Consult with the manufacturers; they can guide you properly. Select the same company and check the manuals carefully.

Preceding the process despite power differences can result in irreversible damages. You can estimate the power capacities of devices by comparing the torque and rotations per minute.

Same Brand

In this method, it is essential to take both types of equipment from the same manufacturer. A manufacturer builds every product on the same ideology, and power capacity remains ideal.

You can complete this method in a vehicle with or without the mechanic’s help by just reading the manuals. Understand one gadget, and the second becomes more comfortable for you.

Take out the truck engine

First of all, remove the equipment of the pickup, clean it, and then remove the parts. The whole process for removing this requires the removal of bolts.

You should assemble all of these so that they can be reused. If you are not experienced in this, label all the screws and bolts when they are removed. You can also take pictures of every step so that you can repeat the process.

Wear rubber gloves to protect your hands from any damage of fluid. First of all, drain the radiator’s fluid and start removing all the bolts attached to the device.

Use a bucket for removing and collecting the drain fluid. The bucket should be at least five-gallon in size. You can also put a truck engine in a boat.

Now you should remove the radiator and fan from the automobile. You can read the instructions manual, which comes in a handy form.

This can help you with any technical issues. Take a wrench and loosen the pump. Do not completely disconnect the pump; otherwise, it can suddenly bump out. Lose the pump to the extent that it can quickly move out towards you.

Keep on opening the electrical wires; there is no need to remove the spark plug altogether. Take the wrench and loos the manifold of the exhaust. Take out all the bolts which are connecting the transmission, once they are removed, you can continue the process.

Now uplift the pickup with the help of a jack. Make sure that the jack is good enough to hold the weight of the pickup. Place the jack stands for better safety and carefully move under the vehicle.

Remove the connectors and exhaust pipes and remove the jack. Lose all the transmission and mount connections with a wrench.

Wrap a heavy chain around the device, keep the front part higher, and start pulling the equipment towards you.

Take out the car engine

First of all, wear protective gloves for safety. Disassemble the vehicle by removing the alternator and lowering the radiator hose. Remove the water pump, air compressor, battery, and manifold of exhaust by using wrenches.

Take out the air condenser of the automobile. Loosen the power steering pump and starter with wrenches of different sizes. You can also add a truck horn in your car.

Use a screwdriver and open the bolts of the transmission shift cable and linkage connections. You should remove all the wiring attached to the parts. Open all the nuts and bolts with wrench and drivers; now drain the fluid of the automobile.

Uplift the automobile on the uplifting jack with protective stands. Slide it under the vehicle and support all mounts. Strap it with a heavy solid chain; you can also use seat belts to stabilize it. Pull it slowly towards you and push it backward. It is a must that you remove the heavy rust from the truck frame before doing this.

Add the truck engine in a car

Placing it inside an automobile is a relatively comfortable and easier method. Wear the safety gloves before doing this installation in your vehicle. Use a hoist and slowly lower it into the body.

Consider the connection of the transmission as a priority. Make sure that the shafts of the drive match the input shaft of the transmission area.

Now secure all the bolts to the transmission connections and then install the mounts of the motor. Always use new mounts, old parts can harm in terms of safety.

Place it in its place and start attaching the manifold of exhaust and air conditioning systems. Connect the radiator and hoses before the belts and other accessories.

Connect wires and accessories

Carefully reinstall the vacuum connections and fuel lines in an automobile. Connect the throttle cables and other things and check that all the wires are connected safely because fuel and vacuum connections are critical.

Set the wiring and attachments in a way that they do not touch the warm parts. Excessive heat can damage the wires, and this can result in a sudden breakdown of power.

You can use the computer to confirm if both are of the same power and manufacturer. You can use the old computer gadget because most companies do not supply a new one.

Add the fan

In this step, make sure that all the connections are accurately installed. Moreover, reinstall the manifold of the air intake inside the device.

Put the battery in its place and connect the fan belts carefully. New types of equipment come with all the accessories installed in them. Some manufacturers do not provide extra screws and intake gaskets; in such cases, you can choose them accordingly.

You can also use all the parts and accessories if they are in good condition and suits your vehicle. All of them should be clean and inspected before use. In the end, check all the connections and wires.

If there is any problem, then resolve it before starting the fan. Double-check the bolts and attachments and do not crank the vehicle before the proper inspection. If your diesel truck is blowing black smoke, check all the parts.

Add the fuel and battery

Refill all the drained fluids and another break-in fluid, which are recommended by the manufacturer. You can only use those fuels which are related to the specific model.

Read the manuals carefully or consult with the manufacturer. An irreverent fluid not only damages but also reduces their battery timings. Move the parts for five minutes, and fluid moves in the line of the pump.

Until the fluid filling is complete, do not run it for more than two thousand revolutions per minute. Follow these instructions for at least one first hour.

You can change the oil of the battery after the first five hundred miles. Place the battery inside for proper functioning.

Keep an extra battery with you while performing the procedure at home. Install the new battery and check its battery time. Avoid excessive and rough driving for saving the battery timing and other issues.

Start the car

After placing the battery and fuel inside, you can start your vehicle. Check that all the parts are working correctly.

If you hear any sound, check which part of the vehicle is cranking and fix it properly. In the first hour, run the vehicle for some time without moving it. This can make your vehicle idle higher, which is beneficial for all drivers.


Wiring is a complex system that can confuse many fellows. Cooling systems may not work correctly if the wires and accessories are not attached correctly.

Most people just do not consider the importance of their functionalities, and eventually, the fans stop working.

Cost of procedure

This procedure is a bit heavy on your budget. The average cost of swapping an engine is between $3000 to $4000.

This amount can increase with the quality and condition of the vehicle. You can consult with the nearby mechanic about the expenses.
