Whats the Cummins updated # for the Non-cycling thermostat in a 1995 CTD truck? Thanks

richard

The number that I have for the revised thermostat is
Cummins Part # 3934373
The notaion with it says- Eliminates temp fluctuation
but engine warmup is slower and operating temp is lower than previous thermostats.

hope this helps

My '95 was cycling like mad and Cummins part # 3934373 took care of the problem. Got it @ Cummins...can't remember the price but it was not bad.<br><br>Michael

Just replaced mine in November '02. These were the part numbers and prices I paid at Cummins Atlantic. When you call the Cummins place near you, be sure to give them the serial number and/or CPL of your engine.<br><br>3928499&nbsp;&nbsp;&nbsp;32.20<br>3 927305 (gasket)&nbsp;&nbsp;&nbsp;4.80<br>3925466 (seal)&nbsp;&nbsp;&nbsp;1.25<br>
