WARNINGDisconnect and isolate the battery negative (ground) cable before beginning steering wheel removal or installation. Allow the front airbag system capacitor to discharge for two minutes before removing the steering wheel or any front airbag system component. This will disable the front airbag system. Failure to disconnect the battery could result in accidental front airbag module deployment and possible personal injury. Do not place a non-deployed airbag face down on a hard surface as the airbag will propel into the air if accidentally deployed, and could result in serious or fatal injury.

Scheme 32: DESCRIPTION

Glow plugs are used to help start a cold or cool engine. The glow plugs will heat up and glow to heat the combustion chamber of each cylinder. An individual glow plug is used for each cylinder. Each glow plug is threaded into the cylinder head below the cylinder head cover.

Scheme 33: DESCRIPTION

Variable valve timing solenoid assembly. The solenoid receives pulse width modulation signal and the current is controlled within 0 ma to 1000 ma. The spool position is controllable at any position to control supply of oil between the advance and retard ports.

CAUTIONHandle the spark plugs with care. Do not drop or force the spark plugs into the wells, damage to the electrodes and/or porcelain body may occur. Always start each spark plug by hand in order to avoid cross-threading the spark plug in the cylinder head. Always tighten spark plugs to the specified torque. Too much or not enough torque will cause damage to the cylinder head and/or spark plug and may lead to poor engine performance.
  1. Install each spark plug to the cylinder head. Tighten spark plugs to 27 N.m (20 ft. lbs.).
  2. Install ignition coil onto spark plug.
  3. Install ignition coil mounting bolt. Tighten to 9 N.m (79.5 in. lbs.).
  4. Connect ignition coil electrical connectors.
  5. Connect the negative battery cable.
WARNINGDisconnect and isolate the battery negative (ground) cable before beginning steering wheel removal or installation. Allow the front airbag system capacitor to discharge for two minutes before removing the steering wheel or any front airbag system component. This will disable the front airbag system. Failure to disconnect the battery could result in accidental front airbag module deployment and possible personal injury.
