hello,

this is my first time on forum..... i have a 2008 sts v with 71k miles, just had radiator replaced & mechanic said NEVER again; picked up an evaporation code: P0442 ( small evap leak ) turns out not gas cap, but canister above gas tank. Is there any way to fix without

removing rear frame & gas tank & who knows what else ??? Love this vehicle !! Any direction would be GREATLY appreciated. Can it be

accessed via rear seat or trunk ?? HELP...... Thanks
