However, if you're determined to do it yourself, here's a *general* outline. Specific procedures will vary depending on your engine type. Consult a repair manual specific to your 1995 Pontiac Grand Am GT's engine for detailed instructions, torque specifications, and diagrams. A Haynes or Chilton manual are good options.
General Steps (Highly Simplified):
1. Preparation:
* Safety First: Disconnect the negative battery terminal.
* Gather Tools and Parts: You'll need a complete set of metric sockets, wrenches, screwdrivers, a torque wrench (essential!), a head gasket set (including new head bolts or studs), possibly a new timing chain/belt (depending on the engine), coolant, oil, and other related fluids. Consult your repair manual for a precise list.
* Workspace: Work in a clean, well-lit area with good ventilation.
* Repair Manual: Have your repair manual readily available.
2. Removal:
* Disconnect Components: Disconnect all components connected to the engine: hoses, wiring harnesses, sensors, etc. Label everything meticulously to ensure correct reassembly.
* Remove Accessories: Remove components like the alternator, power steering pump, intake manifold, etc. Again, refer to your manual for the correct order.
* Remove Cylinder Head: Remove the valve covers, camshaft(s), timing chain/belt (if applicable), and finally the cylinder head bolts. Carefully remove the cylinder head. Be prepared for it to be heavy.
3. Inspection and Cleaning:
* Inspect Cylinder Head: Inspect the cylinder head for cracks or warping. It may need to be resurfaced if warped.
* Inspect Engine Block: Inspect the engine block for damage.
* Clean Surfaces: Thoroughly clean the mating surfaces of the cylinder head and engine block using a suitable cleaning agent.
4. Installation:
* Install Head Gasket: Carefully install the new head gasket, ensuring it's properly seated.
* Install Cylinder Head: Install the cylinder head, ensuring it's properly aligned.
* Torque Head Bolts: Tighten the head bolts in the sequence and to the torque specifications specified in your repair manual. This is crucial to prevent warping.
* Reinstall Components: Reinstall all components removed in step 2, following the reverse order and referring to your manual.
5. Final Steps:
* Refill Fluids: Refill coolant, oil, and other fluids.
* Check for Leaks: Check for coolant and oil leaks.
* Start Engine: Start the engine and let it run for a while, monitoring for leaks and unusual noises.
Important Considerations:
* Torque Specifications: Using the correct torque specifications for the head bolts is absolutely critical to prevent head gasket failure. Improper tightening can lead to a warped head or cracked block.
* Engine Timing: If your engine has a timing belt or chain, you'll need to set the timing correctly after reinstalling the cylinder head. This is a complex process and requires precision.
* Professional Help: If you're not comfortable with any of these steps, seek professional help. A poorly done head gasket job can lead to catastrophic engine damage.
This is a simplified overview. Again, consult a repair manual specific to your vehicle's engine before attempting this repair. Improper repair can result in serious damage to your engine. The time and effort required significantly outweigh the cost of having a qualified mechanic perform this repair for most individuals.
