I'm working on a 1997 Buick Skylark, 2.4L. I didn't notice as I was removing the exhaust manifold the studs are not all the same length. One stud is ~10mm longer than the rest. Anyone know where the longer stud is located on the head?
Thanks
I think I got it located. It's to allow for the bracket that supports the coolant hose and tube between the water outlet and the coolant reservoir .
