1996 Dodge w/ Cummings
Greetings! Brand new here and I thought I would try out a question for some help. I have been experiencing, for a while now, water temp fluctuations. I have a 1996 Dodge with the 6 cylinder Cummings. I bought the truck new and it doesn't have any real modifications from factory. While driving, I am getting readings from 150 deg to 180 deg in about 2 minuets. I can go for 50 miles and it will be steady. Then, for no reason it moves up or down. I have had installed a new water pump, thermostat, fan clutch, sending unit, and two complete system flushes. What in the world is going on? Any advice is greatly appreciated.

Its a Cummins not Cummings

Yup Cummins and the guage moving is just your thermostat opening and closing. :c:
|
Would you belive auto correct misspelled Cummins. That's my story and I'm sticking to it.

Must not have the updated cummins t-stat. The gauge cycles much less with it. It drives me nuts watching it.
Here is the cummins part number you need. 3934373 |
It bugs the heck out of me whe people say Cummings..
but I do have to agree my auto-correct tries to chage cummins to cummings :s: either way, a quality cummins t-stat should help |
Same stuff happens to me, I think its just the auto parts store thermostats. I need to get a Cummins one in there.

So 3 hours of driving later, the gauge stays put. |
The way I see it A giood cooling system is a beautiful thing, I can watch the guage fluctuate all day. :yeah:

Completely normal. As others have said, it's just the thermostat opening and closing.
In 1998 (IIRC) they changed that because people were concerned. If you ride in a newer one, you'll notice it doesn't fluctuate like that -- not because the temperature doesn't really fluctuate, but because it kind of dumbs it down -- takes an average if you will. Basically, if it DOES NOT fluctuate, you might have an issue, otherwise you're fine. |
