Oil and filter replacement for the Peugeot Partner

Let's see how to change the oil and filter on the Peugeot Partner's engine. Open the bonnet and remove the oil filler cap. It is recommended to use a cleaning product before changing the oil for a better result. For this, leave the car running for 5 minutes, pour in the cleaning product, and let the engine idle for another 10 minutes. Lift the front of the car and support it on two axle stands, remove the plastic undertray if present to access the oil drain plug. Place a collection bowl under the plug and loosen it with a 21mm socket, allowing all the oil from the sump to drain out. Once finished, replace the new plug and tighten it initially by hand and finally with the socket. To access the filter, disconnect the air intake hose to unscrew the filter flange with a ratchet and a 27mm socket. Position the collection bowl underneath to catch any oil inside the filter. Remove the rubber gasket from the flange and replace it with a new one after lightly greasing it. Remove the old filter and replace it with a new one, applying a thin layer of oil on the contact surfaces and ensuring correct installation. Refit the flange and tighten using a torque wrench to 25Nm. Reconnect the air hose, reattach the undertray, and remove the axle stands. Add approximately 90% of the new oil, run the engine for a few minutes, and check the correct level with the dipstick, topping up if necessary.
