Pioneer Automotive Industries 851006 engine cylinder head stud for the 1966-1969 Chevrolet Impala V8 7.0L, the 1970-1976 Impala V8 7.4L and other vehicles fastens the cylinder head to the engine block. It is a threaded stud, so the head sits over it and a nut tightens it down.
A stud that is bent, broken or has damaged threads shows up when the head is off, and oil or coolant seeping at the head gasket joint can be another sign. Before you replace a stud, rule out a leaking head gasket, a damaged thread in the block and a warped head surface, since any of them can leak at the same joint.
This head stud is a direct-fit replacement for the 1966-1969 Chevrolet Impala V8 7.0L, the 1970-1976 Impala V8 7.4L, the 1975 Chevrolet Malibu V8 5.7L and the 1969 Chevrolet Camaro V8 7.0L. The 1975 Chevrolet Malibu V8 5.7L takes one.
