i have 2006/7 5.7L 350 mag MPI Fresh water cooled engines.
Based upon the parts diagram, appears the coolant is flowing through the manifolds, 2 hoses each side, upper and lower manifold. They should be protected from the salt water. Is there a reason I would need to replace the manifolds, and not just the risers and exhaust elbows when time comes in 2-3 years (last replaced in 2016)?
