PROBLEM
Show/hide table
| Certain aftercooler cores could have possibly been manufactured incorrectly and may be missing the internal baffle. The missing baffle separates the inlet and outlet ports, which can result in high inlet air temperatures due to poor coolant flow in the aftercooler. |
ACTION REQUIRED
