Hi,

I'm new here and most of you will probably think that this is a silly question but...can someone tell me what the cooling system capacity is on an '83 635 euro? I can't find it any where.

Thanks

12 liters (12.7 quarts) of phosphate free ethylene glycol and don't forget to bleed the system with the bleeder screw on the thermostat housing.

Thanks for the info. I did bleed it but didn't see any bubbles come out. Of course, when I tried to loosen the bleeder valve screw the top snapped off of it. Luckily they're still available at the dealer.
