'99 3.1L ENIGNE- spark plugs

V6 front wheel drive...

can the plugs on the firewall side be removed from above or do you have to go below?

I not sure about the 99 3.1L V6 but on my 90 3.1L V6, I have to remove the bolt of the dog-bone from the engine side and loosen the bolt on the frame side. I use a pry bar or any metal bar on the engine lift eye-hook and turn the engine forward. Once I move the engine forward, I put back the bolt from the engine side but I put the bolt on the middle hole (bottom side) of the dog-bone. The engine should have tilted enough for me to remove the spark plugs from the top.

take the engine mount the top off put it in drive then shut off the motor will move forward that what we do at my car shop.
