2007 Buick Terraza Parts Questions & Experts Answers

• Q: How to replace spark plugs in an engine on 2007 Buick Terraza?

  A: The replacement of spark plugs requires waiting for engine temperature to cool down to avoid threads in the Cylinder Head from seizing while protecting them from damage. Remove all foreign debris from the Spark Plug recess to stop material contamination in the Cylinder Head threads which could cause improper Spark Plug seating. The correct Spark Plug for your vehicle must be used alone since alternative plug temperatures will harm the engine heavily. Start the procedure by removing both the air cleaner outlet duct and the intake manifold cover whenever needed. First disconnect the left Spark Plug Wires and then use engine rotation to gain better workspace before removing the right Spark Plug Wires and associated spark plugs. Verify the gap of all new and reconditioned spark plugs with a round wire feeler gauge since their pre-installed gaps might have changed. According to ignition system specifications adjust the new spark plugs and install them while torqueing them to 15 n.m (11 lb ft). You must reconnect both right side Spark Plug Wires once the engine returns to its original position and finally reconnect the left side Spark Plug Wires. Reinstall the intake manifold cover together with the air cleaner outlet duct if these components needed replacement during the service period.
