    Posted: 26 Jun 2022 at 6:19pm
I’ve read several posts on here with issues of 7060and 7000 series overheating., And tried all the fixes
I have a 7060, low hour tractor. Never had a working temp gauge until about a week ago. It always ran around 200 with a laser thermometer however it started getting worse.   The previous owner had removed both stats.   It also had no foam around the rad.   I put in new 180 stats, complete foam kit, belts tight. Rad professionally rodded , new water pump, timing at 18 degrees.    After putting in the thermostats it overheats within minutes baling hay.   It will run about 200 at idle but shoots sky high when running at rpm. I’m stumped and desperately need the tractor. Any help would be greatly appreciated. Thank you!!!

If you put in 180 degree thermostats and it runs 200 at idle, i would think the thermostats are not right or blocking flow.

You can also have an air pocket in the system after doing work on the thermostats and radiator. Normally you can bleed air a high point in the system to burp the air.

Are you still using the lazer to verify 200 degrees ? ... I would check the temp going INTO the radiator and OUT of the radiator, in addition to around the Thermostat housing.

Thanks for the reply.   My “new water pump” had a cracked hub on the impeller. Needless to say the impeller was barely turning so I had virtually no circulation.
