Official summary
Some 2015-2017 transit vehicles equipped with a 3.2l puma diesel engine may exhibit an overheat condition due to coolant loss without any external coolant leaks. This may be due to an internally leaking exhaust gas recirculation (egr) cooler. To correct this condition, install revised egr cooler ck4z-9u433-b. Refer to workshop manual (wsm), section 303-08. Use causal part 9u433 and applicable labor operations from section 09 of the service labor time standards (slts) manual.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
