How do you change the spark plugs on a 2000 Mitsubishi Mirage 1.8 liter?

Answer 1

1)With hood raised properly you should always disconnect the battery, but it isn't absolutely nec.

2)Remove the 2 bolts that hold the ignition coil down above the spark plugs on top of the cylinder head. Note (there are 2 coils and 2 plug wires) ((Tools you will need: 10mm socket, 3" extension (1/4" drive), 1/4" ratchet)

3)Once the bolts are removed, disconnect the wiring connectors (not the spark plug wires) from the coils.

4) Twist the 2 spark plug wires and 2 coils slightly about 1/4" turn to keep them from sticking while you try to remove them.

5) Pull gently, at first, upwards to remove (ONE AT A TIME) the 2 spark plug wires and 2 coils from the cylinder head. Note:(they may stick so you may have to pull slightly harder to remove them than your original effort) (Repeat this step for each of the 4 cylinders)

6) Once the spark plug wire or coil with boot is removed you need to remove the plugs. Insert the ratchet, extension, and socket assembly down into the cylinder head until the socket fits snugly unto the spark plug. Turn counter-clockwise unti lthe plug loosens. Once the plug is entirely loose remove it from the cylinder head. ((Tools you will need: 5/8" spark plug socket w/boot, 10" extension (3/8" drive), 3/8" ratchet)

7) Remove old plug from the spark plug socket and replace with the new plug.

8) Reverse and repeat the steps to reinstall each plug. Of course make sure you torque the plugs to spec and gap your plugs!!!
