T4.75 with Cab Overheating

[lowellcantrell]

2014 Powerstar T4.75 with Cab overheats everything AC is on while running at 2000 rpms or higher. Screens, all coolers, and radiator washed everyday (screens cleaned multiple times). Coolant flushed and replaced. All filters and fluids replaced annually.. AC is cold, but engine overheats. I'm thinking there is too much garbage in front of radiator ( AC cooler. Transmission cooler, Fuel line cooler, AC filter and housing). Thought about adding extra fan, but I would have to cut a hole in the hood because there is no room under the hood. Any other T4.75 owners have this problem? Any ideas how to correct the situation and eliminate engine overheating?

Overheating is not an endemic problem with T4.75 tractors. Replace your thermostat maybe?

I found a very slight seep around an oil cooler clamp by the radiator and years of dust stuck to it blocking off 1/4 of the coolant radiator with a hardened mud. I couldn't see the blockage until I separated the radiators and was able to pressure wash the fins. I bet I washed a cup of dirt out.

never ran into this problem with mine. I've had a leak, because the hose clamp wasn't tight, but that's it. I can work all day with AC on, mowing fields with the screen half full of crap. I'd take the thermostat out and check it for proper operation, other than that gotta be the radiator or the water pump.

Or as suggested, a load of debris between the condenser, oil cooler and radiator.
Some folks do not understand how to slide the front unit clear of the radiator.

Are you washing the rad with water? I find it better to blow out with air vs water. Water ends up being a dirt magnet and the rad fins get plugged with cemented dust.

It's a six year old tractor, how long has it been an issue?
If it has just started this year something has changed.
Separate the stack and check each one separately use some coil cleaner or soapy water to clean each.
