Here's a general outline. Specifics will vary depending on the year and model of your Puma:
1. Safety First:
* Disconnect the battery: This prevents accidental shorts and protects electronic components.
* Wear appropriate safety gear: Gloves, eye protection, and potentially a respirator (exhaust systems can be rusty and contain harmful particles).
* Work in a well-ventilated area: Exhaust fumes are toxic.
* Support the vehicle securely: Use jack stands, never rely solely on a jack.
2. Gather Tools and Materials:
* Jack and jack stands: To lift the vehicle.
* Socket set (metric): Various sizes will be needed.
* Wrench set (metric): For stubborn nuts and bolts.
* Ratchet and extensions: To reach difficult areas.
* Penetrating oil (like PB Blaster): To loosen rusted bolts.
* New gaskets: These are usually needed for reassembly.
* Possibly a heat gun or propane torch: To help loosen stubborn bolts (use caution!).
* Gloves and safety glasses: Essential safety equipment.
3. Exhaust Removal Process (General Steps):
* Locate all exhaust components: This will typically include the catalytic converter, exhaust pipes, muffler, and any hangers or brackets.
* Start at the rear: Begin by disconnecting the muffler. This usually involves removing bolts holding it to the tailpipe and hangers.
* Work your way forward: Carefully disconnect each section of the exhaust system, one by one, working towards the engine. This will involve removing nuts, bolts, and potentially clamps. Use penetrating oil liberally on all bolts beforehand.
* Support the exhaust system: As you remove sections, support the weight of the remaining exhaust to avoid damage.
* Disconnect oxygen sensors: If applicable, carefully disconnect any oxygen sensors attached to the exhaust.
* Remove hangers and brackets: Carefully remove the exhaust hangers and brackets that secure the system to the vehicle's undercarriage.
* Lower the exhaust system: Once all connections are disconnected, carefully lower the exhaust system to the ground.
4. Reassembly (in reverse order):
* Install new gaskets: This is crucial for a proper seal and to prevent leaks.
* Reconnect hangers and brackets: Ensure everything is aligned correctly.
* Reconnect exhaust sections: Tighten all bolts and nuts to the manufacturer's specified torque.
* Reconnect oxygen sensors: Make sure they're securely connected.
* Lower the vehicle: Once the exhaust is reconnected, lower the vehicle carefully.
* Reconnect the battery: Once completed, reconnect your battery.
Important Considerations:
* Consult a repair manual: A factory repair manual specific to your Ford Puma's year and model is invaluable. It will show you exactly where all the bolts are located, what size they are, and the correct torque specifications.
* Rust: Older vehicles are more likely to have rusted bolts, making removal more difficult. Penetrating oil is your friend here.
* Exhaust system components: The exact layout and parts may vary slightly depending on your Puma's specific model and optional extras.
This is a simplified overview. The actual process can be more complex and time-consuming, especially if you encounter rusted or seized parts. Again, if you're not comfortable with this level of car repair, seeking professional help is strongly recommended. Improper exhaust removal can lead to damage to your vehicle and potential injury.
