PROBLEM

Show/hide table

The existing NRS cooler can fail on certain 336F, 340F, 352F Excavators, 725, 730 and 735 Articulated Trucks, 772G Off-Highway Trucks, 826K Landfill Compactors, 966, 972 and 980 Wheel Loaders, D6T Track-Type Tractors, and PM620 Cold Planers. If the existing NRS cooler fails internally it can lead to coolant getting into the air system and potentially cause additional engine damage.
