  Q: How to replace spark plugs in an engine on Chevrolet Uplander?

  A: Start the Spark Plug replacement process only when the motor has cooled down to protect both the engine threads and stop them from seizing. Chasing dirt away from the Spark Plug recess will prevent it from contaminating the Cylinder Head and causing unsatisfactory new plug installation. The vehicle requires its precise spark plugs because engine damage occurs when replacing them with plugs having different heat levels. Start the procedure by detaching the air cleaner outlet duct followed by removing the intake manifold cover when they exist. The left Spark Plug Wires should be disconnected then engine rotation may be needed for proper access when removing right Spark Plug Wires and the actual spark plugs themselves. A round wire feeler gauge should be used to check the gap in new and reconditioned spark plugs during their installation because pre-installed gaps might have changed since manufacturing. The installer should first gap the new spark plugs according to ignition system specifications before installing them with torque set to 15 n.m (11 lb ft). After positioning the engine at its initial setting reinstall the Spark Plug Wires on the right-hand side and proceed with reconnecting the plug wires from the left side. Reinstall the intake manifold cover with the air cleaner outlet duct after both components were previously unbolted.
