Hey guys: New member here and I used the search bar before posting to see if this topic had been covered and didn't find anything, so here goes... I have a 2013 T870 that I use on my poultry farm occasionally and do some forestry mulching on the side. The hours are getting kind of high on the machine (3500) and its beginning to run warmer than I would like and the hydraulics are getting hot quicker. With another South Mississippi summer coming on fast, I was wondering if you guys could give me some suggestions as to what I could do to help keep temps down and extend the life of the machine. Currently, it gets blown out twice a day on the job, pressure washed after every 40 or so hours and I just cleaned the radiator and all with industrial grade foaming A/C coil cleaner. I'm currently running AW68 Hydraulic oil and its still going to almost 200 degrees If you happen to know of a mechanic or shop in South MS that I could use, even better. Thanks in advance.
 
You can check your cooling fan solenoid to make sure the fan is running fast enough. They get crud stuck in the stem of the valve. We have replaced a couple and have to do 1 in our s650 this week

I'll do that. I have 3 days or so left on my current job and am planning to do a full coolant flush and change the thermostat, so I'll give it a look. Thanks.

I doubt if the engine and hydraulic cooling systems share any radiator space like an automatic trans on a car, but Redline makes a product called Water Wetter that improves cooling efficiency. It's an emulsifier that breaks the surface tension of the coolant and lets it absorb heat faster from the block and lose it faster in the radiator.
Don't know if it would help on the hydraulic issue, but it can't hurt.
