how do you get to the back plugs to change them on a92 caddiac?

get you a plug socket and ratchet, then turn the L right outta the cadillacmaking it a caddiac

On some transverse engines,you could take the upper motor mount strut mounts loose at engine and pull forward on motor.

you might have to get to them from under the car.

if its a DeVille its really hard. i have a 1993 DeVille and it was really hard to reach. you need some1 with small hands.
