i cant remember off the top of my head but think it its a DOHC 8v engine it should be the 3 digit maybe found at rear of cylinder block on transmission flange to rear of exhaust manifold. but if its the V6 the code maybe found on front face of cylinder block and cylinder head. but if you still cant find it go to www.etis.ford.com that might help i have got it all at work but not there for another week
