Freightliner XCS chassis air, what is this mounted near my radiator?

Hello-

Please see circle in picture below. What is that?

Thanks!

Sorry, was thinking that was the front. It's getting too late for me.

Windshield washer pump ?

Honestly, I took that picture just as I had spend a long day washing, waxing, and getting the rig ready for winter storage. I just noticed it, took a picture, made sure the fluid level was between min and max, and drove it to the storage facility. I've meant to ask before as I've owned this rig for a while now, but kept forgetting.

Definitely not a windshield washer pump or fluid. That's up front.

The only "fluid" I can figure is that it is transmission fluid? The brakes are air brakes so I'm assuming there's no fluid associated with them. It's not coolant because there is a separate reservoir for that.

Power steering fluid reservoir

The transmission will usually have a dipstick similar to the engine oil. That is likely hydraulic fluid.

Ah, forgot about that fluid. Yes, could be. It does have a red-ish fluid color. The reservoir in the manual looks different, but I've seen other discrepancies between my chassis and the chassis manual illustrations

Power steering, be cautious it probably takes ATF. My 2014 35B did.
