2000 Chevrolet Malibu Timing Chain Parts Questions & Experts Answers

• Q: What precautions should be taken when servicing the timing chain on an interference engine on 2000 Chevrolet Malibu?

  A: Manuals from gm omit information about interference engine status while performing Timing Chain service. Therefore drivers must exercise caution during these operations. No motion should be applied to Crankshaft or Camshaft during cylinder block installation when the Cylinder Head is present unless proper Timing Belt/chain installation and Camshaft timing verification exists. The engine should never run backward while a suspected broken or "jumped" timing belt/chain requires starter engagement must be avoided. When performing manual engine rotation and feeling a "catch" do not apply additional force over the limit of the "catch." when working with overhead cam engines where the Cylinder Head needs removal you must avoid laying the combustion chamber side-down on any flat surface. Upon re-installing the Cylinder Head, ensure that the Crankshaft and Camshaft gears align with their respective timing marks or confirm that all shafts are set to tdc for cylinder #1 before placing the Cylinder Head onto the cylinder block. To verify valve damage from Timing Chain/belt failure or timing mishaps while the engine runs, each cylinder needs pressurized air after closing the valves.
