Improved Gasket Available For Engine Oil And Brakesaver Oil Cooler

Usage:


3406 Truck Engines With BrakeSaver

Description of Change: A new gasket is now used between the bonnet and the cooler core on the engine oil and BrakeSaver oil coolers. The new gasket is a beaded gasket. It will give a better seal in this application.

Leakage was possible with the former gasket because of the distance between bolt holes.

Adaptable To: The 1W7361 Gasket is a direct replacement for the former 9N87 Gasket which is canceled. Two gaskets are needed for each engine.
