Tips for engine installation include removing the hood, disconnecting the battery, taking a picture of the electrical wiring harness, unplugging throttle cables, fuel lines and hoses that lead to the radiator and draining the radiator before removing it. Lubricating the new engine, using an engine hoist to remove the old engine and position the new engine in its compartment, and gathering the necessary tools before starting the project may be helpful. Break in the engine if it is not dyno-tested.
To install an engine, first park the vehicle on a flat surface, unsecure the hood hinge bolts, and remove the hood. Unplug the negative cable of the battery, and remove the battery. Take pictures of all wires, and pry them off. Unplug all cables that connect to the engine, as well as all fuel lines and vacuum hoses before draining coolant, oil and other fluids. Remove all connections to the transmission, hoist the car with a floor jack, and unfasten the exhaust manifold from the tailpipe.
Loosen the motor mounts, and unsecure them from the transmission. Lower the vehicle. Use an engine hoist to lift the engine out of its compartment. Carefully check the replacement engine to confirm if it is in proper condition, and connect any necessary parts.
With the help of the engine hoist, carefully place the engine in its position. Reconnect the transmission, and attach new mounts to the transmission. Replace the radiator, hoses, air and fuel supply lines, and other connections. Pour fluids into their appropriate compartments, bolt the hood in place, replace the battery, and reconnect it. Start the car, and test the installation.
