Engine oil and filter of Fiat Punto renewal

1 Frequent oil and filter changes are the most important preventative maintenance which can be undertaken by the DIY owner. As engine oil ages, it becomes diluted and contaminated, which leads to premature engine wear.
2 Before starting this procedure, gather all the necessary tools and materials. Also make sure that you have plenty of clean rags and newspapers handy to mop-up any spills. Ideally, the engine oil should be warm, as it will drain better, and any impurities suspended in the oil will be removed with it. Take care, however, not to touch the exhaust or any other hot parts of the engine when working under the vehicle. To avoid any possibility of scalding, and to protect yourself from possible skin irritants and other harmful contaminants in used engine oils, it is advisable to wear gloves when carrying out this work. Access to the underside of the vehicle Fiat Punto will be greatly improved if it can be raised on a lift, driven onto ramps, or jacked up and supported on axle stands. Whichever method is chosen, make sure that the vehicle remains level, or if it is at an angle, that the drain plug is at the lowest point.
3 Slacken the drain plug about half a turn using an Allen key (see illustration). Position the draining container under the drain plug, then remove the plug completely.

4 Allow some time for the old oil to drain, noting that it may be necessary to reposition the container as the oil flow slows to a trickle.
5 After all the oil has drained, wipe off the drain plug with a clean rag, then clean the area around the drain plug opening and refit the plug. Tighten the plug to the specified torque.
6 Move the container into position under the oil filter, which is located on the front right-hand side of the engine.
7 Using an oil filter removal tool if necessary, slacken the filter initially, then unscrew it by hand the rest of the way (see illustration). Empty the oil in the old filter into the container.

8 Use a clean rag to remove all oil, dirt and sludge from the filter sealing area on the engine. Check the old filter to make sure that the rubber sealing ring has not stuck to the engine of Fiat Punto. If it has, carefully remove it.

9 Apply a light coating of clean engine oil to the sealing ring on the new filter, then screw it into position on the engine (see illustration). Tighten the filter firmly by hand only - do not use any tools.
10 Remove the old oil and all tools from under the car then lower it to the ground (if applicable).
11 Withdraw the dipstick, and remove the oil filler cap from the cylinder head cover. Fill the engine of Fiat Punto, using the correct grade and type of oil. An oil can spout or funnel may help to reduce spillage. Pour in half the specified quantity of oil first, then wait a few minutes for the oil to run to the sump. Continue adding oil a small quantity at a time until the level is up to the MAX mark on the dipstick. Refit the filler cap.
12 Start the engine of Fiat Punto and run it for a few minutes; check for leaks around the oil filter seal and the sump drain plug. Note that there may be a delay of a few seconds before the oil pressure warning light goes out when the engine is first started, as the oil circulates through the engine oil galleries and the new oil filter before the pressure builds-up.
13 Switch off the engine, and wait a few minutes for the oil to settle in the sump once more. With the new oil circulated and the filter completely full, recheck the level on the dipstick, and add more oil as necessary.
14 Dispose of the used engine oil and filter of Fiat Punto safely. Do not discard the old filter with domestic household waste. The facility for waste oil disposal provided by many local council refuse tips generally has a filter receptacle alongside.
