Engine/Transmission (1994 - 1998) Engine Coolant temp?

[CNichols]

Ok here is my problem or my question rather.



My truck never gets "hot" I have never even seen 190* (even in the summer months) on my temp gauge. It takes forever to warm up. The highest I have seen it get is about 3 or 4 needle widths from 190 and as soon as it gets there the T-stat opens up, and it drops nearly out of the normal range. then comes back up and stays dead center bottom of the normal range and 190 on the gauge. And fluctuates (spelling?) Is this normal? Do they (CTD) ever run at a constant temp? Am I hurting it running so cool seeing as how a diesel needs to be rather hot/warm to run its best?





Also I put a piece card board between the Itercooler and the Radiator this morn with an aprox, 6" round hole in the middle and it still acts the same way. It warms up faster but thats about it.





Thanks in advace.

These motors fluctute a lot in water temp. The whole block isn't cooling that fast, its just reading the cooler water coming in from the radiator. The block probably only varies a couple degrees. If you want, you could try and changing the T-stat. But i think that is more work than it is worth it.

If you want to see it get warm hook 8 to 10K lbs of trailer behind it and storm up a long grade. It's that kind of usage that requires a cooling system like our trucks have. If you are running around with very little load on flat ground it will behave just like you are seeing. No problem.
