Some of the coolant i= s going to vaporize.  This pressurises the system.  Some of tha= t vapor will never go back into solution so there should be pressure in t= he system even when cold. 

 

Dave; this may = be the weak link in your logic chain.  Why would some of the vapor n= ot re-condense?  I hope there is some other reason for the pressure.=   I=92d hate for you to have to tear open the engine.<= /P>
