PROBLEM
Show/hide table
| The existing exhaust cooler (NRS) may show signs of an external coolant leak from the end cap gasket joint on certain 324E, and 329E Excavators. This leak will be seen as a very slow (of order of drips) leak coming from the middle bolt, seen at the off engine side of the cooler. If the existing exhaust cooler leaks it may reduce the overall system coolant level and may lead to a engine derate condition from overheating if the coolant level is not regularly maintained. This leak does not affect the internal gas or coolant path or any down-stream or up-stream components to the exhaust cooler. The external leak from the gasket affects 3497395 and 3750550 Exhaust Coolers only. |
