[DML] Re: Coolant self-bleeder antics

["ronin5030" <yahoo@xxxxxxxxxxxxxx>]

I got my kit from Toby at delorean-parts.com and installed it this 
afternoon. Toby also sent me a personal email advising that air may 
not only be trapped at the water pump (what the self-bleeder bypass 
solves) but also at the rad. He suggested loosening the small hose at 
the top right side of the rad to release any air there too. When I 
did there was a little coolant, bubbles and then air! It wasn't much 
but enough to cause an air lock.

When I warmed the engine I could feel the coolant flowing through the 
bypass and the fans kicked in normally a little while later. 

Could it be possible that you still had some air in the rad that 
worked it's way through the bypass after cooling off?

P.S. A big Thanks to Toby for the advice.
