Greetings All,

I'll be doing a flush and change on my car's cooling system soon.
I've located both drain valves (block and rad). But I need to
locate the coolant bleeder valve to release any trapped air
in the cooling system. Can anyone tell me where it is located
on a 1988 300E (103 engine)?

I attempted a search on the subject, but could not find
the info I needed.

Thank you in advance,

bluebenz
