Disclaimer: This is a general guide. Specific steps may vary slightly depending on your exact engine (2.0L Zetec is the most likely in a '99 Contour 4-cylinder). Always consult a repair manual specific to your vehicle year and engine for precise instructions and torque specifications. Improper repair can lead to engine damage.
Tools you'll likely need:
* Repair Manual: Absolutely essential. This will provide detailed diagrams and instructions.
* Socket set and wrenches: Various sizes, depending on the fasteners holding the tube and surrounding components.
* Screwdrivers (Phillips and flathead): Possibly required depending on how the components are attached.
* New oil dipstick tube: Ensure you purchase the correct part for your specific engine.
* New gasket/seal: The tube likely has a gasket or seal where it meets the engine. Replacing this is crucial to prevent leaks.
* Shop rags or paper towels: To clean up oil spills.
* Gloves: To keep your hands clean.
* Possibly a pry bar or plastic trim removal tool: For gently prying off any plastic covers.
* Torque wrench: To tighten bolts to the manufacturer's specified torque.
General Steps (Consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery cable. This will prevent accidental shorts.
2. Drain the Engine Oil: Before starting any work near the engine, drain the engine oil to minimize the amount of oil spilled during the repair.
3. Access the Dipstick Tube: This usually involves removing parts that obstruct access to the tube, which might include the air filter housing, parts of the intake manifold, or other components depending on the exact placement of the dipstick tube. Your repair manual will guide you on which parts to remove.
4. Remove the Old Dipstick Tube: Carefully remove any fasteners securing the dipstick tube. The tube itself might be pressed in or have retaining clips. Take pictures as you go to help with reassembly. Be prepared for oil to spill during this stage.
5. Clean the Area: Thoroughly clean the area where the tube sits on the engine block or valve cover to ensure a good seal for the new tube.
6. Install the New Dipstick Tube and Gasket: Install the new gasket or seal in its designated location. Then, carefully insert the new dipstick tube, ensuring it's seated correctly. Tighten fasteners according to the torque specifications in your repair manual.
7. Reassemble: Carefully reassemble all the components you removed in step 3, reversing the process. Double-check to make sure everything is securely tightened.
8. Check for Leaks: Once everything is back together, carefully inspect the area around the new tube for any leaks.
9. Refill Engine Oil: Add the correct amount of engine oil (check your owner's manual).
10. Check Oil Level: Check the oil level with the new dipstick.
Important Considerations:
* Plastic Components: Be gentle when removing plastic components, as they can easily crack.
* Torque Specifications: Tightening bolts too much can strip threads or damage components. Use a torque wrench to ensure proper tightening.
* Professional Help: If you're uncomfortable with any part of this process, it's always best to consult a qualified mechanic. This repair can be challenging for someone without prior mechanical experience.
Remember: This is a general overview. Always use a repair manual specific to your 1999 Ford Contour 4-cylinder for detailed and accurate instructions. Failing to do so could result in damage to your vehicle.
