Ask a Question-
is there a specific reason this t-stat is not recommended for a 2014 and newer?
The 1999-2013 Cummins thermostats have a slightly different physical shape and design that fits the earlier model thermostat housing. In 2014, Ram made a change to the cooling system and the thermostat housing, so the older style thermostat will not fit correctly in the newer trucks.
