Engine: Service Precautions
CAUTION^ Wear appropriate work clothing, including a cap, protective goggles and protective shoes when performing any work.
^ Remove contamination including dirt and corrosion before removal, installation or disassembly.
^ Keep the disassembled parts in order and protect them from dust and dirt.
^ Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly and replacement.
^ Vehicle components are extremely hot after driving. Be wary of receiving burns from heated parts.
^ Be sure to tighten fasteners including bolts and nuts to the specified torque.
^ Place shop jacks or rigid racks at the specified points.
^ Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from the battery.
^ All parts should be thoroughly cleaned, paying special attention to engine oil passages, pistons and bearings.
^ Rotating parts and sliding parts such as piston, bearing and gear should be coated with oil prior to assembly.
^ Be careful not to let oil, grease or coolant contact the timing belt, clutch disc and flywheel.
^ All removed parts, if to be reused, should be reinstalled in the original positions and directions.
^ Bolts, nuts and washers should be replaced with new parts as required.
^ Even if necessary inspections have been made in advance, proceed with assembly work while making rechecks.
^ Remove or install the engine in an area where chain hoists, lifting devices, etc. are available for ready use.
^ Be sure not to damage coated surfaces of body panels with tools, or not to stain seats and windows with coolant or oil. Place a cover over fender, as required, for protection.
^ Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch coolant and oil, wire ropes, chain hoist, transmission jacks, etc.
^ Lift up or lower the vehicle when necessary. Make sure to support the correct positions.
