During routine vehicle maintenance, a technician performs an engine oil and filter change. In what sequential order should the technician execute the following steps to properly complete the service?
- 1Warm the engine to operating temperature and position a drain pan beneath the oil pan.
- 2Remove the oil pan drain plug to allow the old motor oil to drain completely into the pan.
- 3Remove the old oil filter and install a new filter after lubricating its rubber gasket.
- 4Reinstall and torque the drain plug, then pour the specified volume and viscosity of fresh oil into the filler neck.
- 5Run the engine briefly to circulate oil, inspect for leaks, and verify the final level using the dipstick.
Answer
Warm engine and position drain pan, remove drain plug to empty oil, replace oil filter with lubricated gasket, reinstall drain plug and add fresh oil, run engine and verify level on dipstick.
The correct sequence follows standard shop safety and maintenance protocol: first warming the engine to ensure complete fluid evacuation, draining the used oil, servicing the filter, securing the oil pan drain plug before refilling, and finally running the engine to verify circulation and accurate dipstick level.
