Here's why it's so involved and what you should consider:
* Accessibility: The timing chain is often deeply embedded within the engine, requiring the removal of numerous components to access it. This includes potentially removing the front cover, various pulleys, and possibly even the oil pump.
* Precise Alignment: The timing chain must be installed precisely to ensure proper valve timing. Incorrect timing can lead to bent valves, piston damage, or complete engine failure. This often requires special tools for camshaft and crankshaft alignment.
* Specialized Tools: You'll need a timing chain tool kit specifically designed for the 1993 Ford Tempo's engine. This often includes a chain tensioner tool, crankshaft locking tool, and camshaft alignment tools.
* Potential for Damage: Removing and reinstalling various engine components increases the risk of damage to seals, gaskets, sensors, and other parts.
* Labor Intensive: This is a very time-consuming job, potentially taking a skilled mechanic several hours or even a full day to complete.
Instead of attempting this yourself, strongly consider the following:
* Professional Mechanic: The safest and most reliable approach is to have a qualified mechanic perform the timing chain replacement. They have the expertise, tools, and experience to do the job correctly. Get multiple quotes from reputable shops.
* Cost: Expect to pay a significant amount for professional labor and parts. This is not a cheap repair.
* Assess the Need: Before committing to a timing chain replacement, make absolutely sure that the chain needs replacing. A noisy chain might just need tensioner adjustment or replacement. A mechanic can properly diagnose the problem before recommending such an extensive repair.
In summary: While you *could* attempt this yourself, it's highly discouraged unless you have extensive experience working on engines and possess the specific tools required. The risk of causing further damage far outweighs any potential savings. A professional is the best option.
