There are three steps to the fan, i believe they are about 210, 217, 221 degrees.

 

this one never kicks on until 225. you dont even hear it slightly. i know in mine i can hear it slightly but this one it doesnt do anything. sorry about the thread jack im just also having the same problem

 

ect sensor could be going bad...ran into this on a plow truck. replaced and fan keeps it plenty cool now.

 

that was my next step. are there two on this truck? i know there is one right next to the thermostat but isnt there one by the oil cooler?

 

I would think that if the ECT was going bad, I would notice something while monitoring it with my AE. I have never seen any fluntuations while I was monitoring. My truck has the newest flash as of March 2010.
I sure wish my truck ran at the lower temps that others report and I am willing to do what ever it takes.Hopefully someone has some ideals.

 

cheezit told me to check the front cover and water pump but the sensor isnt that much for me so im going to try that first and if that doesnt work then i guess ill fork out the big money

 

How much is a ECT sensor

 

i think at the most 25 bucks. btw where in tx are you located?

 

Currently living SW of Houston. We are in the process of selling out and moving back to our home town of Bangs Tx. West of Dallas and south of Abilene.

 

Guys, I don't want to come across as a smart ***, but I do want to put this thought out there. Are you guys that are getting hot cleaning your radiators from the outside. I know I have seen several people talk about flushing them, but one of the first things you learn on the farm is that when the water temp starts up, blow out the radiator. I use a 3' long chunk of 1/4 pipe with 5 1/8 holes drilled in the side of it and the end welded shut. If you have never blown out your radiator you will be shocked how much dirt you will get out of it and how much cooler your equipment will run. This is also not a fast process even with a big air compressor this can take an hour or so to do right. Again, if you are already doing this, sorry but I thought someone might be able to use the info.

 

^^^ Thank's. That was brought up on another thread also. Another example how it's good to check the easy/obvious stuff first and we missed it this time.
