New Oil Cooler Bonnets Used On 3408 And 3412 Engines
Usage:
3408 Truck, Marine and Industrial Engines;
3412 Marine And Industrial Engines
Description of Change: New oil cooler bonnets are used on the 3408 and 3412 Engines in the applications shown above. The flange on the new oil cooler bonnets is .093" (2.36 mm) thicker than the flange on the former oil cooler bonnets. Because of the increased thickness of the flange, the spacer plate or block orifice and one of the two gaskets used with the former oil cooler bonnet is no longer needed.
Adaptable As: Direct replacement for the former parts as shown in the chart that follows. See the parts book for the water lines group or expansion tank group used on your engine.
