Here's a general overview, but remember this is *not* a substitute for a proper repair manual:
1. Preparation:
* Safety First: Disconnect the negative battery terminal. Wear safety glasses and gloves. Work in a well-ventilated area.
* Gather Supplies: New oil pan gasket (ensure it's the correct one for your engine), new oil filter, fresh oil (correct weight for your engine), jack stands, jack, drain pan, socket wrench set (metric), torque wrench, pry bar (plastic or wood is best to avoid scratching the pan), clean rags, and possibly a gasket scraper.
* Vehicle Preparation: Warm the engine slightly to thin the oil, making draining easier. Drive the vehicle onto ramps or lift it using a jack and jack stands for safe and convenient access. Never work under a vehicle supported only by a jack.
2. Oil Drain:
* Locate the oil drain plug on the bottom of the oil pan.
* Place the drain pan underneath.
* Carefully loosen and remove the drain plug, letting the oil drain completely. This may take some time.
3. Removing the Oil Pan:
* Disconnect Components: This is where the repair manual becomes crucial. You'll likely need to disconnect various components that may be obstructing access to the oil pan bolts, such as the starter motor, exhaust components or various sensors depending on the engine. Take pictures as you go for reassembly.
* Remove Oil Pan Bolts: Carefully remove all the oil pan bolts. They're usually located around the perimeter of the pan. Keep them organized to avoid mix-ups during reinstallation.
* Separate the Oil Pan: Gently pry the oil pan away from the engine block. Work carefully to avoid damaging the pan or the engine block. The old gasket will likely stick to either the pan or the block.
4. Cleaning and Preparation:
* Clean the Surfaces: Thoroughly clean the mating surfaces of the engine block and oil pan, removing all traces of the old gasket. A gasket scraper can be helpful but use it carefully to avoid scratching. Use a degreaser and clean rags. Make sure both surfaces are completely clean and dry before installing the new gasket.
5. Installing the New Gasket:
* Apply Gasket Sealer (if needed): Some gaskets may require a thin bead of gasket sealer. Check the instructions on the new gasket packaging. Too much sealer can be detrimental.
* Install the Gasket: Carefully position the new gasket on the oil pan. Ensure it sits correctly and evenly.
6. Reinstalling the Oil Pan:
* Position the Oil Pan: Carefully align the oil pan with the engine block, ensuring the gasket is properly seated.
* Install the Bolts: Tighten the oil pan bolts in a star pattern (or as specified in your repair manual). Do not overtighten. Use your torque wrench to achieve the correct torque specification (found in your repair manual).
7. Reassembly:
* Reconnect Components: Reinstall all components that were disconnected earlier, referring to your repair manual and pictures.
* Refill with Oil: Add the correct amount of new oil (check your owner's manual).
* Replace Oil Filter: Install a new oil filter.
* Reconnect Battery Terminal: Reconnect the negative battery terminal.
* Check for Leaks: Start the engine and check for any oil leaks around the oil pan. Let the engine run for a few minutes, then check the oil level.
Important Notes:
* Torque Specifications: Using the correct torque wrench and following the manufacturer's torque specifications is critical to avoid damaging the engine block or oil pan.
* Repair Manual: This is absolutely crucial. The steps and specifics vary greatly depending on your engine.
* Professional Help: If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
This is a simplified overview. Always refer to a repair manual specific to your 1995 Dodge Intrepid for detailed instructions and safety precautions. Improperly performing this repair can lead to significant engine damage.
