• Q: How to replace the ignition coil for cylinder 2 on 2006 Buick LaCrosse?

  A: Begin the Ignition Coil replacement for cylinder 2 by turning off the ignition power then removing the engine cover component. Remove the air cleaner duct from the Throttle Body while you also disconnect the positive crankcase ventilation (PCV) hose from the right bank camshaft cover. Carefully remove Intake Manifold bolts without unfastening the upper Intake Manifold from its position with the lower Intake Manifold. After you remove bolts 1 and 2 from the Intake Manifold brace you can disassemble the brace and shift the upper Intake Manifold toward the lower manifold for sufficient coil removal space while leaving fuel pipes and hoses untouched. First disconnect the electrical connectors for ignition coils before removing bolts along with ignition coils. To install the ignition coils place them into position then bolt them in and set the Ignition Coil bolts at 10 n.m (89 lb in) torque and finish up by reconnecting the Ignition Coil electrical connectors.
