2nd Gen Non-Engine/Transmission Thermostat Leak

[DTullis]

I flushed and refilled the radiator. Also removed the thermostat housing. I now have a VERY slight leak around termostat. Not even a drop just a slight antifreeze discoloration around 2/3s of the housing. Not losing any measurable amount of coolant.



We are pulling the trailer to Idaho in 10 days. I believe that I should replace the thermostat and o-ring. Any other opinions would be appreciated.



Does anyone know the Cummins Part Nos. for the thermostat and o-ring?



Thanks,

On the plus-side... ... it is a dunk-shot to change the o-ring.
