2013-2024 Ram 1500 5.7L Hemi oil and filter change

Idle the engine for two to three minutes if it is cold. Warm oil pours faster and carries more soot and combustion byproducts out with it. On the 5.7 Hemi with MDS, cold oil tends to hang in the top of the block and the lifter valley, so a brief warm-up cycle empties the crankcase more completely. Do not run the truck long enough to make the exhaust scalding.

Chock the rear wheels, drive the front onto ramps or lift with a two-post hoist. The oil pan sits low and to the driver side of the crossmember. The 13mm hex-head drain plug is on the passenger side of the pan, angled slightly downward. On DT-generation trucks with the aero skid plate, remove the four 8mm bolts holding the small plastic access panel to expose the plug.

Position the drain pan directly below the plug. Break the plug loose with a ratchet, then finish by hand while pressing inward against the pan flange. Once the threads release, pull the plug straight away so it does not drop into the pan. Let the oil drain fully - a warm 5.7 pan empties in about five minutes. Inspect the plug magnet for large metal chips before wiping it clean.

Wipe the pan boss and confirm the crush washer is intact and flat. If the washer is dished or cracked, fit a new one. Thread the plug in by hand two turns to confirm it is not cross-threaded, then torque the oil pan drain plug to 25 ft lbs (34 Nm). Verify against your service manual. Do not over-torque - the 5.7 pan is aluminum and stripped drain-plug threads are a common shop failure on this truck.

The spin-on oil filter is mounted vertically on the passenger side of the block, below the exhaust manifold and behind the front tire. Slide the drain pan directly beneath it. Access is easier from the passenger wheel well than from under the truck.

Fit a 24mm socket or 76mm cup wrench squarely on the base of the filter. Break the filter loose with a ratchet, then spin it off by hand while keeping it upright. Once the gasket clears the block, tip the filter into the drain pan and let it drain. Wipe the mounting surface on the block clean and confirm the old gasket did not stick to the boss. A double-gasketed filter is an instant oil leak the first time the engine starts.

Pour clean oil into the new filter until it is roughly half full, then smear a thin film of fresh oil around the filter gasket. Thread the filter onto the block by hand until the gasket touches the mounting surface. Continue by hand exactly three quarters of a turn beyond gasket contact. Do not use a wrench for final tightening - the Mopar filter seals reliably at hand-tight plus three quarters, and the socket flats round off if wrench-torqued past that.

Remove the yellow oil fill cap on the passenger valve cover. Pour in 7.0 US quarts (6.6 liters) of 5W-20 full synthetic through a long-neck funnel. Reinstall the cap and start the engine. Watch the dashboard oil pressure indicator - it should extinguish within three seconds. Let the engine idle for one minute, then shut it down. Wait five minutes for the oil to settle back to the pan, then check the dipstick. The proper level is at the upper hash mark on the dipstick with the truck on level ground; add small amounts if the level reads below the mark.

Turn the ignition to Run without starting. Fully depress the accelerator three times within ten seconds. The dashboard will flash a confirmation and the oil life percentage will reset to 100. Turn the ignition off.

Start the truck again and idle for two minutes. Walk around and inspect the drain plug and filter for any weeping. A dry filter neck and dry pan boss with warm oil circulating is the confirmation that the job sealed correctly.
