– Wrench set
– Socket set
– Torque wrench
– Transmission jack (optional)
– Engine alignment tool
– Oil filter wrench
– New engine, fluids, and gaskets
Step 1: Engine Removal
**a. Prepare the Workspace:**
– Park the vehicle on a level surface and secure it with wheel chocks.
– Elevate the vehicle using a floor jack and support it on jack stands for stability.
– Disconnect the battery negative terminal.
**b. Remove Ancillary Components:**

– Detach the electrical wiring harnesses, coolant hoses, and vacuum lines.
– Unbolt the transmission mounts and remove the driveshaft (if applicable).
**c. Lift the Engine:**
– Position the engine hoist over the engine.
– Attach the hoist to the engine lifting points using chains or cables.
– Slowly and carefully lift and support the engine.
**d. Detach Engine Mounts:**
– Using a wrench or socket set, unbolt the engine mounts that connect it to the vehicle frame or subframe.
– Lower the engine slightly to detach it from the mounts.
**e. Remove Engine:**
– Carefully pull the engine out of the engine bay.
– Use caution to avoid damaging any surrounding components.
Step 2: Engine Installation
**a. Prepare the Engine Bay:**
– Inspect the engine bay for any damage or loose debris.
– Clean and seal any leaks or damaged areas.
– Install new engine mounts on the vehicle frame or subframe.
**b. Position the Engine:**
– Carefully align the engine with the transmission and engine mounts.
– Use an engine alignment tool to ensure proper positioning.
– Lower the engine onto the mounts.
**c. Bolt Engine Mounts:**
– Securely tighten the bolts that connect the engine mounts to the vehicle frame.
– Use a torque wrench to ensure proper torque specifications.
**d. Reattach Ancillary Components:**
– Install the driveshaft (if applicable), transmission mounts, and electrical wiring harnesses.
– Connect the air intake, exhaust manifold, fuel lines, coolant hoses, and vacuum lines.
**e. Lift and Secure:**
– Slowly and carefully lift the engine into place using the engine hoist.
– Secure the engine using the bolts that connect it to the engine mounts.
Step 3: Finishing Touches
**a. Install Oil Filter and Fluids:**
– Replace the oil filter and fill the engine with new oil and coolant.
– Check fluid levels and top off as necessary.
**b. Connect Battery:**
– Reconnect the battery negative terminal.
**c. Test Engine:**
– Start the engine and check for any leaks, unusual noises, or vibrations.
– If detected, inspect and adjust as needed.
