Tools You'll Need:
* Wrench: The correct size to fit the sending unit (likely a 7/16" or 1/2" wrench, but double-check). A socket wrench is often easier to use.
* Socket and ratchet: Preferably a deep socket to access the sending unit easily.
* Drain pan: To catch any spilled oil.
* Rags or shop towels: To clean up spills.
* New oil pressure sending unit: Make sure you get the correct one for your engine.
* Gloves: To keep your hands clean.
* Optional: Penetrating oil (like PB Blaster) to help loosen the sending unit if it's stuck.
Procedure:
1. Safety First: Make sure the engine is completely cool before you start. Hot oil can cause serious burns. Park on a level surface and engage the parking brake.
2. Locate the Sending Unit: The oil pressure sending unit is usually located on the engine block near the oil filter. Consult your repair manual for the exact location on your specific engine.
3. Drain Some Oil (Recommended): It's a good idea to drain a small amount of oil from the engine's oil pan before removing the sending unit. This minimizes the chance of a significant oil spill. Locate the oil drain plug and have your drain pan ready.
4. Remove the Sending Unit: Using the correct wrench, carefully loosen and remove the sending unit. It may be somewhat tight, so be prepared to apply some force. If it's exceptionally stubborn, apply penetrating oil and let it sit for a few minutes before trying again.
5. Clean the Area: Clean the threads on the engine block where the sending unit was located. This will ensure a good seal for the new unit.
6. Install the New Sending Unit: Carefully screw the new oil pressure sending unit into the engine block. Hand-tighten it first, then tighten it using the wrench to the manufacturer's specified torque. Do not overtighten. Overtightening can damage the threads or the sending unit itself.
7. Reconnect Everything: If you drained some oil, replace the drain plug and check for leaks.
8. Check for Leaks: Start the engine and check for any oil leaks around the new sending unit. Let the engine run for a few minutes to warm up. Observe the oil pressure gauge; it should show a reading.
9. Check Oil Level: After running the engine, check and top up your oil level as needed.
Important Notes:
* Torque Specification: This is crucial. Overtightening can strip the threads, while under-tightening can lead to leaks. Always refer to your repair manual for the correct torque specification.
* Oil Type: Use the correct type and weight of motor oil specified for your vehicle.
* Repair Manual: A repair manual specific to your 1996 Dodge Stratus is highly recommended. It will provide detailed diagrams and instructions tailored to your car.
If you're uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. Working with engine oil can be messy and potentially dangerous if not done correctly.
