Hey everybody, I own a 96' Mercedes S600 which was imported from Germany to the US. I'm trying to replace this coolant part, but I don't know if my Benz is with rear AC or without. I have a vent in the center counsel and for the feet in the rear, but I don't have no rear controls. And in my case, dealer is unable to tell. Can someone help me please before I buy te wrong part??

I'm 99% sure that A/C is standard on all W140s for front and rear. I believe some german S600s didn't have separate climate control systems for the rear. From what I understand it was standard on all US models only.

By the way the floor vents are not for A/C.

Well, that's the thing. I have AC control in the front and a vent in the back. When I turn the AC on, it blows cold air in the back, but I have no temperature control in the rear. Just an open or close option. So is this considered with rear AC or without. In my opinion, I would think that without rear AC would have no vent in the back at all.

You don't have rear A/C. The rear air vents just blow cold air. Rear A/C cars have temperature select switches in the rear air vent.

It´s rare in a S600 model, but your 600 model is 100% without a four zone temp.
No rear A/C.

BTW. Replacing the coolant doesn´t have nothing with the A/C.
The coolant is a liquid (50% etileno glicol plus 50% water) that goes at your engine cooling system.
If you are asking about the replacing your gaz system at your A/C you can find the exact
amount at the label in the radiator top.

If you dont have the control panel at rear (three wheels that control fan speed and left/right temperature), that means you dont have the rear AC. It is not standard even for S600 (FYI the rear heated seats are not standard for S600 as well)

The part I am replacing on my engine for my cooling system calls for with rear AC or without rear AC because the parts are slightly different.

@jcmbz My 600 does have the rear heated seats option :D

Thanks guys!! now I know my car is without rear AC.

rear air / Euro 140s

In Europe the rear air conditioner was never standard, not even on an S600, and is a very rare option. It was quite expensive.
If there are three little wheels at the rear grille, its a 4 zone, if not, it just blows unconditioned fresh air.

On my 92 500 the rear vent blows A/C but not heat there are only two options, on and off and directional louvers. If you had the optional rear heat and A/C there is a separate unit in the lower armrest glove box. Heat comes out of the vents under the seat, the unit had adjustible control wheels (temp and fan speed) and was fed by both heater lines and A/C refrigerant
