• Q: How to replace the ignition coil for Bank 2 on 2007 Buick LaCrosse?

  A: Begin Ignition Coil replacement for bank 2 by switching off the ignition then removing the engine cover without disconnecting fuel pipes along with hoses. Engine replacement of coils for cylinder 2 requires disconnecting the air cleaner duct from the Throttle Body and the positive crankcase ventilation (PCV) hose from the right bank camshaft cover while avoiding separation of upper from lower Intake Manifold components. Start by uninstalling the Intake Manifold bolts then remove the Intake Manifold brace bolts (1 and 2) and brace before repositioning the upper Intake Manifold with the lower Intake Manifold to create enough space for Ignition Coil removal. Begin by disconnecting the Ignition Coil electrical connectors followed by removing Ignition Coil bolts before finally removing the ignition coils. Install the ignition coils into position by following the service precautions regarding fasteners. Then secure the Ignition Coil bolts with torque to 10 n.m (89 lb in) before reconnecting the Ignition Coil electrical connectors.
