  Q: How to replace the Distributor Cap, Distributor Rotor and Spark Plug Wire on SOHC and V6 engines on Mitsubishi Galant?

  A:

  The replacement of the distributor cap and rotor is common on all 1998-present V6 engines. All models must have spark plug wires checked on the recommended schedule, or when a misfire-type driveability issue occurs. To start with, inspect the spark plug wires visually when the engine is running in a darkened area, staying clear of moving parts. Replace all spark plug wires if arcing is seen. For DOHC four-cylinder and 1999 and later model four-cylinder engines, perform checks with the engine off, inspecting wires one at a time to maintain proper order. To avoid damaging the ignition coil pack, remove the spark plug wire by twisting it off first. Investigate the internal boot for corrosion. Make expert assessments to ensure the boot fits snugly on the spark plug and ignition coil terminal. If necessary, crimp the connection. Clean each wire, check for damage, repeat for all wires. When you need new wires, buy a full set and change each wire one by one so the firing order doesn't get mixed up, and that both ends are seated tightly on the coil pack and spark plugs. For four-cylinder engines equipped with a distributor and for all V6 engines, remove the air intake duct and air filter housing. Disconnect one spark plug wire from the distributor cap and install it in the same location on the new cap. Take off the old distributor cap and rotor and check for wear and damage to install a new one if required. Remove the spark plugs without clipping the wires back onto the clips. Then replace the spark plug wires one at a time, making sure they seat securely. Finally, replace the air intake duct and air filter housing. On V6 engines, remove the tape or rags from the lower intake manifold and then install the upper intake manifold.

  Q: Should Distributor Cap, Distributor Rotor and Spark Plug Wire be checked whenever new spark plugs are installed on Mitsubishi Montero?

  A:

  Whenever new spark plugs are installed, the spark plug wires should be inspected, starting with a visual inspection that can be performed at the dealer or in a dark garage with good ventilation while the engine is running. Examine each plug wire for arcing or little sparks at the site of damage. If damage is found, new wires will be needed. After the engine cools, the distributor cap and rotor should be checked. Make sure to check each spark plug wire independently to ensure they remain in the correct order. Use a numbered label or tape if necessary. To disconnect the wire from the spark plug, simply twist the rubber boot and pull it free. Do not pull on the wire itself. Ensure there is no corrosion in the boot and fit tightly when fixing it back. Wipe the wire with a rag and examine it for burn marks or cracks. Do not comfortably bend the wire. Remove the wire at the distributor and observe for corrosion and fit before replace. After checking all wires, if replacement is necessary, then purchase a set specific to your engine model. Replace one wire at a time to maintain firing order. To check for cracks or worn contacts, you must remove the distributor cap. Take off the rotor and check it too, replacing any damaged parts. It's best to put a new cap and rotor on with new spark plug wires. If you're re-using the old cap, however, you should clean the terminals. Make sure to move the wires to the new cap one at a time to avoid getting them mixed up.
