Too Cold For The Fan...

oh ok. i thought it was getting up to temp rapidly and too often and causing fan to come on
sorry

 

My gauges are analog as well, I have a 2000 379 with a 97 3406e. I have a scan guage, which gives me readings from the ecm. Bought it about 7 years ago and it was $159

 

I suppose the earlier E models could be slightly different but I know my 6nz doesn't demand fan to come on for engine temp until 217. I don't recall what temp sets off the alarm. And I'm pretty sure that 217 degree number goes for almost all the electronic cats. 6nz, mbn, and acerts.

Like I said the earlier e models could be different but wouldn't think they are that far off

 

I use a scangauge D to watch what the ecm sees for water temp.

 

I guess my question should have been are you sure you've gotten it warm enough to make fan engage or get a warning light?

I do believe the early E models were different but the number at which fan is demanded on can not be changed with a different file or anything else. Man guys have asked to have it lowered but it can't be altered
