What You'll Need:
* New oil: Check your owner's manual for the correct type and quantity (usually 5-6 quarts).
* New oil filter: Again, check your owner's manual for the correct filter.
* Oil filter wrench: The type depends on your oil filter; some are cap-style, others require a strap wrench.
* Wrench for drain plug: Usually a 13mm or 14mm. Consult your manual.
* Drain pan: Large enough to hold at least 6 quarts of oil.
* Funnel: To avoid spills when adding new oil.
* Jack and jack stands (or ramps): Essential for safe access to the drain plug. Never work under a vehicle supported only by a jack.
* Gloves: To protect your hands.
* Rags or paper towels: For cleanup.
* Torque wrench (optional but recommended): To tighten the drain plug to the correct specification.
Steps:
1. Warm up the engine: Run the engine for 5-10 minutes to warm the oil, making it flow more easily. Don't let it get too hot, though.
2. Secure the vehicle: Park on a level surface, engage the parking brake, and use jack stands to securely lift the front of the truck. Never work under a vehicle supported only by a jack. If using ramps, drive the truck onto them slowly and carefully.
3. Locate the oil drain plug: It's located on the bottom of the oil pan, usually towards the front of the engine.
4. Position the drain pan: Place the drain pan under the drain plug.
5. Remove the drain plug: Carefully loosen and remove the drain plug using the appropriate wrench. Let the oil drain completely; this may take 15-20 minutes. Be careful as the oil will be hot.
6. Locate the oil filter: It's usually located near the oil pan.
7. Remove the oil filter: Use the oil filter wrench to remove the old oil filter. Have a rag ready, as some oil will spill out.
8. Lubricate the new filter's gasket: Lightly lubricate the rubber gasket on the new oil filter with a bit of fresh oil.
9. Install the new oil filter: Screw on the new oil filter by hand until it's snug. Then tighten it according to the manufacturer's instructions (usually about ¾ to 1 full turn after the gasket contacts the engine).
10. Reinstall the drain plug: Once the oil has finished draining, reinstall the drain plug and tighten it to the manufacturer's specified torque (consult your owner's manual). Do not overtighten!
11. Lower the vehicle: Carefully lower the vehicle using the jack.
12. Add new oil: Using the funnel, add the correct amount of new oil as specified in your owner's manual.
13. Check the oil level: Use the dipstick to check the oil level. Add more oil if necessary to reach the "full" mark.
14. Run the engine: Run the engine for a few minutes.
15. Check for leaks: Inspect the drain plug and oil filter for leaks.
16. Check the oil level again: After running the engine, turn it off and let it sit for a few minutes. Check the oil level again and add more if needed.
17. Dispose of used oil properly: Take the used oil to a recycling center or auto parts store that accepts used oil.
Important Notes:
* Safety First: Always prioritize safety. Use jack stands, wear gloves, and work in a well-ventilated area.
* Consult your owner's manual: This guide provides general information. Always refer to your owner's manual for specific instructions and recommendations for your 2003 Dodge Dakota.
* Torque Specifications: Using a torque wrench to tighten the drain plug ensures you don't overtighten or undertighten it, preventing leaks or damage.
If you're uncomfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic. This is just a guide; improper procedures can damage your engine.
