To change the oil filter on a 2012 Dodge Grand Caravan, access the top‑mounted cartridge housing by removing the engine cover and air intake duct, then use a 24mm socket to unscrew the cap.
With a few basic tools and about 30 minutes, you can handle this maintenance yourself and save on shop labor.
Preparation and Parts Needed
Before you start, gather the following: 6 quarts of SAE 5W‑30 oil (MOPAR recommended), a cartridge oil filter (includes a new O‑ring), a 24mm or 15/16″ socket, a 13mm socket for the drain plug, a torque wrench, jack stands, safety glasses, and a drain pan. The filter housing sits on the passenger side of the engine under the air intake duct.
| Specification | Detail |
|---|---|
| Oil Type | SAE 5W‑30 (all temperatures) |
| Capacity with filter | 5.9 quarts (round to 6 quarts) |
| Filter type | Cartridge, top‑mounted |
| Drain plug torque | 20 ft/lbs |
Step‑by‑Step Filter Removal
Park the van on a level surface, raise the front on jack stands, and chock the rear wheels. Remove the engine cover by pulling it straight up. Loosen the clamps on the air intake duct with a flathead screwdriver and disconnect the duct to expose the filter housing. Place a rag under the housing, then use a ratchet and 24mm socket to loosen the filter cap counterclockwise. Unscrew it by hand once loose. Lift off the cap and pull out the old cartridge filter. Discard the old O‑ring from the cap’s groove.
Install New Filter and Refill Oil
Insert the new filter into the cap, ensuring the clips lock into place. Roll the new O‑ring onto the cap until fully seated and lubricate it with a little clean engine oil. Slide the cap back onto the housing and thread it by hand until snug – do not use a wrench to tighten the cap, as over‑tightening can damage the housing. Now drain the old oil: locate the 13mm drain plug near the exhaust, crack it loose, then remove it by hand. Remove the oil fill cap to speed drainage. Once drained, wipe the plug and pan, rethread the plug by hand, and torque it to 20 ft/lbs with a torque wrench. Lower the van and add 6 quarts of 5W‑30 through the filler cap using a funnel. Wait a few minutes, check the dipstick, and top off if needed. Start the engine and run for one minute, then inspect for leaks at the plug and filter. To reset the oil life indicator: turn the ignition to ON (do not start), press the accelerator pedal three times within ten seconds, turn the ignition OFF, and restart.
FAQs
What happens if I reuse the old O‑ring?
Reusing the old O‑ring is the most common cause of oil leaks after a filter change. The new O‑ring included with the cartridge filter must be installed and lightly oiled to ensure a proper seal.
Can I use 5W‑20 instead of 5W‑30?
No. The 2012 3.6L engine requires SAE 5W‑30 for correct lubrication and performance. Using 5W‑20 can lead to inadequate protection and potential engine damage.
How often should I change the oil and filter?
Dodge recommends changing the oil and filter every 3,000 to 7,500 miles, depending on driving conditions. Replace the filter with every oil change to keep the engine running clean.
