6690 overheating

JDSNOW · Apr 13, 2013

I have a 6690 that always claims it is hot. I have changed the sender and reads the same. It does not seem hot to the touch even when gauge says melt down. I can overheat it at idle. Every thing is clean. Does any one know what the oil temp should be between? All the gauge says is hot or cold. I would like to check oil temp with another tem gauge. Thanks

We have a 6690. Tell me more about your tractor. How many hours on it? Your sure the cooling fan is working, no loose or broken belts? Have you ever used compressed air to blow any accumulated dirt off the individual cylinder heat fins? Is your oil level correct? What about the oil cooler on the right side of the engine, is it clean?? We wait till August to mow our pasture and we pull a rhino mower in 100 degree temps and she runs always cool. Ryan

Something is wrong, they always run so cool, like was said- check the blower operation + blow it out good, any oil lesks to the outside collects dust + dirt and really affects the cooling, check the condition of- and the oil helps to keep things cool too, real important

All the cleaning has been done. It reads hot but seems cool even when I pull the covers and touch everything. It only gas 2000 hrs on it. Yes the fan turn well also. I want to install a trans temp gauge where the factory gauge goes but that gives me temp readings. I was hoping some one would have the service manual so I know how hot is too hot in degrees.
