Cummins N14 thermostat replacement


Recommended Posts

  I will be changing the two thermostats in our n14 in a few weeks. The parts are on the way and will install them in a few weeks.


  On the Cummins n14 there is a water transfer tube that has to be taken off at the same time. There is a o'ring at each end of that tube that should be replaced. But I am curious as to what to use when the new o'rings are installed. Pure silicone lube or what.


  I have searched the web but so far have not found the answer.


  Thanks in advance,.    Vern
