Changing the coolant yearly and running the AC weekly during the winter kept mine working the SLC until the engine died, and it sat for three or four years while I rebuilt it. I bought a new unit at what I thought was the borderline of theft shortly after I got the car - I think it lasted five years before I let it sit too long.

[MBZ] '77 300D ACC2 widget
I am cleaning up the 123, and one of the long-term issues is that the ACC blob under the hood leaks coolant. It is a slow leak, and I had bypassed it for winter, but I figure I would like to fix it before I sell it. Plus, it's a challenge that doesn't require me being outside while the kids are sleeping. :) At first I thought the gasket was bad, but then I realized one of the screws couldn't be tightened - I guess the PO stripped it because it had some old glue holding the screw in place. I scraped that off, but now I'm left with a long screw that doesn't have anything to grip, and the same low-pressure leak. 1) Can I just shoot JB-Weld into the screw hole, then drill and tap it for a slightly-narrower screw? Is there a better way? I would like to leave the screw removable if at all possible. 2) The case of the top half (i.e. above the coolant section) is cracked. I am wondering if I can just put a band around it and cover it with epoxy, or if I should try to source another blob. I imagine the blob would be expensive, unless I happen to get lucky in the junkyard - since this is pre-sale cost is a serious factor. 3) How do you get the electrical parts out of the blob? I can get to the metal sheet, and the geared motor clearly moves the contacts around on some traces, but I can't figure out how they inserted the electrical components (and presumably vacuum etc.). Since it looks like someone has repaired this one, I am afraid of breaking it when those parts might still work. :) Thanks, Tim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
