Because Details Matter: Vibration is the quiet enemy of an aluminum radiator, and the right rubber cushions are what stand between it and years of wear. A fresh set in the correct locations keeps the radiator isolated and the power steering cylinder properly mounted, the kind of small detail that protects bigger, costlier parts down the line.
