On a 1994 3.5 engine, the plugs are at the bottom of deep wells. The spark plug cables enter the top of the engine with a rubber plug that conceals the hole. Pulling this plug out reveals a rubber stalk several inches long that snaps on to the top of the plug at the bottom of the hole. Use a spark plug socket with a rubber insert that catches the plug to remove the plugs. You can use a piece of hose to thread the new ones so you don't misalign the threads. Don't tighten the plugs too tight. Firm is good but don't crank them in with all your strength. Also--if you are replacing the cables you need to buy a set that fits the year, make, and engine of your car.
there is six spark plugs
number #1 spark plug is located (if u are looking under hood) right side first one closest to you. NOTE* TO REPLACE SPARK PLUGS ON A CHRYSLER 3.5 LITER V-6 YOU MUST ALSO REPLACE UPPER PLENTIUM GASKET!!!!
It is important to know how the engine of a car works. In a car, the spark plug cables connect to the vehicles spark plugs.
I think its a 94 , 4 cylinder.
Disconnect the battery of the car, remove the cables and boot covers, and remove the old spark plugs. Put in the new spark plugs, replace the cables and boot covers, and connect the battery.
