How to Replace an Engine

Below guide will teach you How to Replace an Engine. Please follow the instructions carefully.

Things You’ll Need:

  • Combination Wrench Set
  • Scribe
  • Socket and Ratchet Set
  • Pry Bar
  • Engine Hoist
  • Engine Assembly

Estimated Costs:

  • DIY Costs: Est. $2,462.91 parts only
  • Shop Costs: Est. $4,076.17 parts and labor

Instructions:

  • Turn on the engine and allow it to become warm.
  • Halt the spark and fuel delivery to the engine.
  • Take all the spark plugs out. Attach the compression gauge to the spark plug threads, starting from the first cylinder.
  • Once the compression gauge is positioned in the cylinder, turns the throttle plate open and told your assistant to crank the engine by means of five compression strokes. Take the reading.
  • Perform the compression test for each of the remaining cylinder and take the reading of each of them. Compare the readings and make sure that all the readings fall within the range of 5-10psi.
  • Consider a cylinder with low pressure and add small amount of oil via spark plug hole into the cylinder. Wait for some time before checking the cylinder compression again.
  • Put all the spark plugs back to their positions and connect all the wiring connectors again. Turn the engine on and make sure that the vehicle is running as it did before the compression test.
  • Turn the engine off and discard the negative battery cable from the terminal.
  • You may have to take the engine hood out of its place to make enough space for engine hoist.
  • Remove the radiator drain plug or disconnect the lower hose to allow the coolant to drain out.
  • Take the air cleaner assembly out. Also, take the radiator and fan shroud out of the vehicle.
  • Remove all the vacuum lines, fuel lines and electrical connections from the engine. Don’t forget to mark them for installation reference.
  • Remove the upper radiator hose and exhaust system from the engine as well.
  • Remove the air compressor, if an air conditioning system is installed on your vehicle.
  • Unbolt the transmission from the engine block.
  • Position the engine hoist over the engine compartment.
  • Now look for at least two possible points on the engine where you can fix the engine hoist to the engine. Normally, a chain is used to secure the engine to the engine hoist.
  • Pull the chain out of the eye of the engine hoist and secure it to the engine block with bolts and washers. Now look for the exhaust bolt holes on the opposite end of engine.
  • Now, attach the chain to the front right of the engine block and support it to the block utilizing the exhaust bolt holes.
  • Move onto the opposite ends and attach the chain to the rear left of the engine block and support it with exhaust manifold bolts using bolt and washers.
  • Next, lift the arm of the engine hoist gradually to rectify the looseness on the chain.
  • As the engine block is secured with chain to the engine hoist, you can take the engine mounts off.
  • Take help from assistant told him to keep the engine steady while you lift the engine hoist gradually so as to move the engine up and out of the engine compartment.
  • Take the engine out and consult any professional engine mechanic to have it repaired for you. Reassemble the engine by reversing the entire procedure.

Tips & Warning

  • While working with the vehicle engine compartment, it is necessary to use Personal Protective Equipment (PPE) to avoid injuries. Protective clothing like safety goggles, latex gloves and closed toe shoes help you prevent severe injuries while performing repair work.
