can i just delete this thing? is it important? hell what is it? what does it do? pre heat the rad fluid with the block heater? i thought it was added on the 82 to help with the waste oil kit. the 2 SDs we have dont have one, and i dont rember seeing one on the 2 300Ds my buddys have... any help would be great guys. thanks in advance.

09-26-2013, 09:41 AM #1well, i thought my 78 was leak free, after sitting in front of the house over night on the brick, i noticed a small stream where it ran down the road to the curb. and its about a gallon shy. so upon inspection this thing is leaking... my 82 has one, but it looks different and not as much running into it i think, i may need to go look at it again. anyways the 78 seems to leak more then the random one on the 82...:igh::: chasing leaks on these old benzs is getting tire some. diesel, oil, tranny fluid, anti freeze. ::hangs head:: any ways pics of this leaking box tied into my rad system.

09-26-2013, 10:00 AM #4They where designed by Chrysler and uses in early w123 and all w116 they are made of plastic and they crack. There is a company that make an aluminum replacement one but they are expensive $800-$1000 . I found one in the junk yard and had in a w116 300sd way back in the day.

09-26-2013, 10:49 AM #7Humm so after i found out what it was, thanks willbehere4u, some searching and it seems that the vac system on it is screwed anyway it only blows on defrost, and the aux pump works so i can delete the valve and let it run straight heat all the time since the ac isnt hooked up anyways. ill proly remove both of them, as long as i have heat to the cabin im good. i dont think i will even venture into playing with trying to repair the vac system on that thing. and im sure as heck not paying more then i have in the car for a new one. thanks again for the speedy reply willbehere4u.

09-26-2013, 04:43 PM #8You could use a cheap heater valve and a choke cable to turn it on and off manually. or a plane garden valve for winter use only

09-26-2013, 07:54 PM #10There is an aftermarket maker of a replacement valve for your application, I would have to look into who it is. It evidently works better than the stock one

09-27-2013, 07:36 PM #13i dont know why the valve is necessary, if the electric pump pumps water to the cabin, then why do you need a valve? with out the valve isnt it just like an old chevy heater core, always having fluid flowing, only not near as much because the pump isnt running... all i know is i have the same amount of buttons working and the heat still blows in the cabin with out the thing and im not leaking rad fluid anymore.

The fact that you even mention mig wire as a fastener discounts your statements
haha we're still rooting for you. They call it the "evil servo" for a reason
