Locating spark plugs on 2003 buick century

I am assuming you have a 3.1 v6 engine the spark plugs are 3 right in the front next to the oil dipstick and above the exhaust manifold you can follow the wires from the coil to find each plug. The other 3 are on the back side of the engine and can be difficult to get to. Easiest way is to remove the upper engine mounts and tilt the engine forward a few inches with a ratchet strap or something to gain clearance. MAKE SURE it is secure because your arms will be back there. And those three plugs are in the same location as others just on the opposite side of the engine.again just follow spark plug wires down to the plug.
