There's an awful lot of talent and experience in these parts so I come for wisdom. The first and only previous Deutz engine I ever built (in 2008) didn't have a hydraulics cooler.
The (yellow) engine oil cooler sits in the air duct and it's exhaust is deflected away from the engine by the deflector, the exhaust of the (white) hydraulics cooler outboard from it is also deflected away from the engine by the bottom flap of the same deflector.
Beyond what could be called serious alignment issues for a factory kit, there seems to be some nonsense in all this. The exhaust of the oil-cooler is actually heating the hood and top of the hydraulic cooler! I have half a mind to redesign it so as to keep the oil-cooler exhaust close by the engine completely separated from the hydraulics cooler by a spaced-isolation baffle allowing the latter to get cooled also.
Unless what the designers had in mind was actually pre-heating the hydraulics in cold weather? I have no idea.
