DO-IT-YOURSELF MAINTENANCE 6 11 1. Remove the engine rocker cover. NOTE: It is recommended that the spark plugs (For 2.7L Engines) should be changed by an authorized Hyundai dealer. 2. Using a clean cloth, remove any dirt that has accumulated around the base of the spark plug so it cannot fall into the cylinder when the spark plug is removed. 3. To remove the spark plug cable, pull straight up on the insulated connector, not the cable. Pulling on the cable may damage the carbon core conductor. ! WARNING: It is recommended that the engine be cool or cold when changing the spark plugs. If the engine is hot, you could burn yourself on the insulated connector, the spark plug or the engine itself. 4. When preparing to remove the old spark plug, guide the socket down over the spark plug, being careful not to damage the ceramic insulator. 5. To remove the old spark plug, turn the wrench handle in a counterclockwise direction. 6. To install the new spark plug, guide the socket down over the spark plug, being careful not to damage the ceramic insulator. HGK5063 NOTE: Spark plugs should be tightened firmly. Over-tightening can damage the threads in the aluminum cylinder head. Also, leaving them too loose can cause the spark plug to get very hot and possibly result in damage to the engine. 7. Replace the cable by pushing the insulated connector directly down onto the electrode. Check to be sure it has snapped into place and can't fall off. HGK5062
