How To Replace The Engine Oil And Filter On A 2011–2023 Chrysler 300: A DIY Guide

By Nick Marchenko, PhD

Hello everyone! Today, we're embarking on a splendid journey through the intricacies of maintaining one of Chrysler's finest, the 300, specifically focusing on the 2011–2023 models. If you're keen on keeping your chariot in tip-top shape without entrusting it to the mystical hands of professional mechanics, you're in the right place. Let's delve into the art of replacing the engine oil and filter, shall we?

The Preliminary Steps

First things first, the protagonist of our tale is the 3.6L Pentastar motor, a marvel of engineering nestled within the heart of our Chrysler 300. Our objective is simple yet vital: replacing the engine oil and filter. Contrary to popular belief, you need not remove any engine covers to access the oil filter housing, a neat little feature designed for our convenience.

However, for the sake of clarity and to aid our visual journey, let's temporarily part ways with the airbox cover. This involves unscrewing an 8mm bolt, loosening a clamp, and disconnecting an electrical connector. Ah, the sweet sound of progress!

The Heart of the Operation

Within the oil filter's abode, a 24mm socket will be your key to unlocking the treasure chest. Twisting this plastic cap should not require Herculean strength; it's designed to be friendly to the touch. Upon its removal, the old filter and its rubber gasket bid adieu, making way for their successors. A crucial tip: always ensure the old gasket's loyalty doesn't cling to the engine. With the new filter and gasket in place, reassemble the housing with a genteel snug. Over-tightening is a cardinal sin here, as we're dealing with plastic, not steel.

The Underworld Adventure

Beneath the carriage lies our next quest: draining the old oil. In some cases, a splash shield might guard the oil pan, but on this occasion, we're unshielded and ready. The drain plug, a 17mm demigod of sorts, requires a counterclockwise twist of faith. Remember, our chariot thirsts for approximately 5.9 quarts of oil, so ensure your collection pan is a worthy vessel. As the old oil bids farewell, consider replacing the drain plug's crush washer, a hero unsung but vital for a leak-free future.

The Final Act

With the stage beneath cleared and the oil pan's guardian retightened, our attention shifts upwards. The oil filler cap awaits its offering of 5.9 quarts of fresh oil. A funnel, a simple yet elegant tool, ensures a smooth pour. Ah, but do not rush this step, for patience is a virtue. Once the new oil graces the engine's insides, a moment of silence is observed. Start the engine, let it breathe, and then check the oil level. Adjust as necessary, for precision is key.
