Oil Change near Diamond Bar, California

To change the oil, a technician allows the engine to cool down, then removes the drain plug at the bottom of the engine oil pan and drains the oil. As the oil is draining they will remove and replace the oil filter. When the oil has fully drained the drain plug is re-installed and the engine is filled with the proper type and amount of new oil. The engine is started and checked for leaks. Finally, the engine is switched off, the oil level rechecked, and the maintenance light reset. While the oil is being serviced, the technician will note any obvious issues with the condition of the engine seals, amount of oil drained, last service date and mileage, and the drained oil's condition. If any abnormalities are noticed, recommendations for diagnosis or repair are made. Most manufacturers have now included panels that are attached to the vehicle's underside; they offer a measure of protection from debris and a means of controlling air flow to the engine and around the vehicle. These panels often completely cover the engine/transmission from below, blocking all access. Removal of one (or more) of these panels and their correct re-installation adds two new steps to the process of an oil change.
