I don't think the temp guage is working on my 6600 diesel. The needle stays in the middle all the time, running or not. I looked it over and it is a capillary tube guage. I looked on JD Parts website and it only shows a temp sending unit for an electric guage. What am I missing, does Deere call the temp guage something else?? I may just go to Napa and buy a temp guage and mount it in the cab. Chris
 
Chris your looking at the parts catalogue wrong. The electric sending unit is to sound the horn on later model JD 6600 and a warning light on earlier ones. The Water temperature gauge is part number AR48640 list is $140 for JD.

I have had good luck with the ones from Abilene Machine and they are $40.

Just Google AR48640 and you will find several suppliers for them.

PS This is the capillary type of temperature gauge.
