Description of Change: The new engine oil cooler and filter base assembly and new engine oil cooler and filter base have stronger mounting flange areas to help prevent cracks.

Adaptable To: The new 108-3879 Oil Cooler And Filter Base Assembly is a direct replacement for the former 9N-3587 Oil Cooler And Filter Base Assembly (this is the longer of the two basic oil cooler groups).
