Here's why:
* Engine Design: The 2.2L engine in the 1998 Cavalier has a relatively simple design, making head gasket replacement accessible without full engine removal.
* Access: There is usually sufficient space in the engine bay to remove the cylinder head, allowing for head gasket replacement.
* Professional Mechanics: Experienced mechanics can typically replace the head gasket without removing the engine.
However, some factors can make it more difficult:
* Severe Engine Damage: If the engine is significantly damaged, or there are other repairs required beyond the head gasket, removing the engine might be necessary.
* Limited Experience: If you're not comfortable working on engines, it's best to take it to a qualified mechanic.
* Specific Circumstances: Certain rare circumstances related to the specific vehicle might necessitate engine removal, but this is unlikely in most cases.
Recommendation:
* Consult a Mechanic: Contact a trusted mechanic for a proper assessment of your specific vehicle. They can determine if engine removal is necessary for the head gasket replacement.
Remember, attempting complex engine repairs without proper experience and tools can be risky.
