7060 thermostat

 On these hot days ive been running around 195 degrees. Does anyone know if you can get 160 degree thermostats to replace the 180 degree. Auto parts store said I had to take it out for them to look at it. I had the radiator shop go over the radiator and it has a new foam kit around it. Im running water wetter in it too.

A lower temp thermostat will not solve your problem.  The coolant flow volume is the same no matter the opening temp of the thermostat, a lower temp just opens sooner it does not allow more coolant to pass through it.  If your running at 195 the thermostat has been completely open since 180 and you still have an additional 15 degrees of temprature rise.  If you installed a 160 thermostat it would just be fully open at 160 instead of 180 and your tractor would still run at 195.  Could be the airflow through the core is not sufficient to remove the heat (could be slipping belts, ect.), or the fins are partially clogged with debris, or the inside of the tubes are scaled up, which impairs proper heat transfer, or a combination of these things, but it is not the opening temprature of the thermostat.  I have found that a really good pressure washing of the fins solves lots of cooling problems.  Spray straight through to avoid bending the fins with the water pressure.  If all else fails you may have to replace the radiator of have it re-cored. 

What kind of horse power are you running?

I have a 7060 turning 210hp and have no trouble keeping it cool pulling a 26ft disc. I have done nothing to the colling system other than putting a waterpump on it, which it needed when I bought it in 04.

did you measure 195 with an infered thermometer or the tractor guage on the dash. Is that on the block or the head, personally 195 does sound like it's real hot to me.

I have an aftermarket gauge on it and the sender is right below the thermostats. Im taking the thermostats out now to put new ones in, but am having a hard time with the bolts. The paints still around them so it doesnt look like its ever been apart. The temp will stay around 195 when im in 2nd slow in fast range. It gets up to 200 when I shift the PD to high though. When it gets to 200 it will start spitting out the radiator tube.

Does this one have two thermostats? I don't remember which ones did but I had one with one bad stat, caused heating as soon as you pulled it, would be fine with no load, thought both my 7030 and 8030 had two, just not sure.

They looked pretty nasty, going to see if Agco has 2 of them tomorrow. With no load it runs right at 180. Seems like if I run it at about 2000 rpm it runs a little cooler than 2300, which seems backwards to me since your moving less water, but I guess less fuel too.
