2006 Cadillac DTS Parts Questions & Experts Answers

• Q: How to replace a spark plug on 2006 Cadillac DTS?

  A: Before replacing spark plugs start by removing the suitable Ignition Coil followed by extracting spark plugs out of the engine when the engine is cool enough to avoid hurting Cylinder Head threads. Clean the Spark Plug recess area thoroughly to prevent foreign substances from getting into the Cylinder Head because such contamination would impair new plug seating; a thread chaser should be used for clean-up. Check spark plugs according to their condition. The vehicle requires only factory-approved spark plugs for installation since other plug temperatures will seriously harm engine internals. New and reconditioned spark plugs require round feeler gage testing because their pre-installed gaps might change in transit. Before placing the Spark Plug(s) into the engine examine their gap which should match specifications exactly. Proceed with the installation when each Spark Plug thread fits the Cylinder Head properly while being completely seated. A thread chaser may be needed to prepare the threads. Install the Ignition Coil while tightening its plug(s) to a torque value of 15 n.m (11 lb ft).
