Review on ACDelco 251 591 Original Equipment Gasket by Kevin Pirlet

Revainrating 5 out of 5

this is not suitable for 6.2L diesel engine

after I received it it was everything else I received does not fit diesel chevrolet 6, 2L and I know that 6.5L is the same. Screw pattern is like 6.2L but it rotates counter clockwise

Pros
  • Uniform wall sections and smooth cavities for coolant flow for efficient operation
Cons
  • Nothing
