2005 Chevrolet Malibu Parts Questions & Experts Answers

• Q: How to replace spark plugs safely and effectively on 2005 Chevrolet Malibu?

  A: Engine replacement of spark plugs should start only when the engine has fully cooled down to minimize thread damage in the Cylinder Head. The Spark Plug recess must be cleaned to stay free from dust and foreign objects that might pollute the Cylinder Head threads thereby blocking the new spark plugs from adequate seating. Spark Plug replacement requires the exact plug model because alternative plugs of different heat levels can cause lasting engine destruction. The process for left bank spark plugs begins by taking off the air cleaner intake duct and following with Spark Plug wire disconnection until you remove the spark plugs themselves. Check all new and reconditioned plugs with a round wire feeler gauge before installation to verify specifications since pre-set gaps might have altered. The spark plugs should be installed with 20 n.m (15 lb ft) tightening torque for new cylinder heads and 15 n.m (11 lb ft) for existing cylinder heads while ensuring smooth thread insertion and complete seat contact; make use of a thread chaser if required. Proper torque measures coupled with spotless threading will help avert overheating as well as exhaust blow-by and thread damages. Reconnect the Spark Plug Wires after following the above instructions.
