That said, here's a general outline of the steps involved. Specific details will vary depending on the exact year and model of your Fiesta 1.3 engine. Always consult a repair manual specific to your vehicle's year and engine code for precise instructions and torque specifications.
General Steps (Consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery terminal. Ensure the engine is cool.
2. Access: You'll need to access the camshaft from above, likely requiring removal of various components:
* Timing Belt/Chain Cover: Remove the cover to expose the timing belt or chain.
* Timing Belt/Chain: Carefully remove the timing belt or chain. Mark the position of everything meticulously before removal. Incorrect reassembly will cause serious engine damage. This often involves using specialized tools to keep the crankshaft and camshaft in the correct position.
* Other Components: Depending on the engine layout, you may need to remove other components like rocker arms, valve cover, etc., to gain access to the camshaft.
3. Camshaft Position Sensor (if applicable): Disconnect the camshaft position sensor.
4. Remove the Camshaft: The camshaft is held in place by bearings within the cylinder head. You'll need to carefully remove any retaining bolts or nuts holding the camshaft in place. Consult your repair manual for the exact location and number of these fasteners.
5. Cleanliness: Before removing the camshaft completely, clean the area around it to prevent any debris from falling into the engine.
Important Considerations:
* Timing Marks: Precisely marking and noting the timing belt/chain alignment is absolutely crucial. Incorrect reassembly can lead to bent valves, engine damage, and non-starting.
* Special Tools: You will likely need specialized tools, such as camshaft locking tools, to keep the components in the correct position during disassembly and reassembly.
* Repair Manual: Obtaining a repair manual specific to your Fiesta's year and engine is essential. It provides detailed instructions, torque specifications, and diagrams.
* Camshaft Seals: When reinstalling the camshaft, pay close attention to the camshaft seals. Replacing them during this procedure is often recommended to prevent oil leaks.
Again, this is a complex procedure. Attempting this without the proper knowledge, tools, and repair manual could result in serious engine damage. If you're unsure about any step, seek professional help from a qualified mechanic.
