How do i change my spark plugs in a 94 volvo 960
The important points to remember are:
1. Use the right tools. Plain socket wrenches can break spark plugs, or cause you to drop them.
2. Be careful handling the spark plug wires, they are fragile and can be damaged by pulling too hard or bending too far. Always twist gently and pull wires firmly by the boot ends, not by the cable, and make sure they are routed and held away from drive belts and hot manifolds. It's a good idea to clean the ends with a little solvent or fuel system cleaner on a rag before reconnecting them.
3. Make sure the new spark plugs match the old in design. If they do not seem the same, take an old plug to the store, and recheck the part listing with a professional.
4. Thread the new plugs in carefully by hand, being careful not to damage or dirty the tips when inserting them, then tighten them gently. Not much force is required to seal spark plugs. Just firmly tight is good.
5. Be sure to reconnect each plug wire to the same plug location it came from. The engine will not run right otherwise.
It's pretty simple. Have a good time with it.

spark plugs are generally easy once you locate them. if you never done this my suggestion is to get the repair manual for your vehicle to assist you with the job.
