However, if you're determined to proceed, here's a general overview of the process. This is a simplified version and may not cover every detail specific to your Tempo's engine (either the 1.9L or 2.3L). Always consult a repair manual specific to your year and engine size for detailed instructions and torque specifications. A Haynes or Chilton manual is a good investment.
1. Preparation:
* Safety First: Disconnect the negative battery terminal. Use jack stands to securely support the vehicle. Wear safety glasses and gloves.
* Gather Tools and Supplies: You'll need a complete set of metric sockets and wrenches, a torque wrench (essential!), a head gasket set (including new head bolts), a gasket scraper, engine degreaser, coolant, oil, a new oil filter, possibly a valve cover gasket, and potentially other seals depending on what you find during disassembly.
* Drain Fluids: Drain the engine oil, coolant, and power steering fluid (if applicable).
2. Removal:
* Disconnect Components: Disconnect various components connected to the engine, including the intake manifold, throttle body, fuel lines, ignition wiring, etc. Take pictures as you go to help with reassembly.
* Remove Accessories: Remove any accessories that are bolted to the cylinder head, such as the alternator, power steering pump, and air conditioning compressor (if applicable).
* Remove the Cylinder Head: This involves removing the valve cover, rocker arms, pushrods (if applicable), and then carefully removing the cylinder head itself. You'll need to loosen the head bolts in a specific sequence (consult your repair manual). Lifting the cylinder head may require assistance.
* Inspect the Head: Carefully inspect the cylinder head for cracks or warping. If it's warped, it will need to be machined or replaced.
3. Head Gasket Replacement:
* Clean Surfaces: Thoroughly clean the cylinder head and engine block mating surfaces with a gasket scraper and degreaser. Any debris will prevent a good seal.
* Install New Head Gasket: Carefully install the new head gasket, ensuring it's properly seated.
* Install Cylinder Head: Install the cylinder head, tightening the head bolts in the specified sequence and torque specifications using your torque wrench. This is critical to prevent warping.
4. Reassembly:
* Reinstall Components: Reinstall all removed components in reverse order of removal. Refer to your pictures and repair manual.
* Refill Fluids: Refill the engine oil, coolant, and power steering fluid to the correct levels.
* Check for Leaks: After refilling, start the engine and check for leaks around the head gasket, valve cover, and other areas. Let the engine run for a while to reach operating temperature.
Important Considerations:
* Torque Specifications: Following the correct torque specifications for head bolts is crucial to prevent head gasket failure. Using a torque wrench is absolutely necessary.
* Cylinder Head Machining: If the cylinder head is warped, it needs to be machined to ensure a flat surface for the new gasket.
* Engine Timing: If you're working on an interference engine (where the valves can collide with the pistons), you'll need to be very careful to not damage the engine during disassembly and reassembly. This may require special tools and knowledge.
Again, this is a highly simplified overview. Do not attempt this repair unless you have significant experience with engine repair. The consequences of improper repair can be very expensive. Consult a repair manual and consider seeking professional help.
