Yes steve, my system has a sealed reservoir above the inlet of the pump whic=
h has the pressure cap  this is 1/2 filled with coolant. Into this empties t=
he heater and various high points of the engine block (sandwich). This T ees=
 into the return from the heat exchanger which keeps a head of coolant to th=
e pump and allows coolant expansion as the air compresses. The system is dis=
connected, now
To allow me to do firewall stuff. Work may be somewhat slowed as the weather=
 here in chicago is in the single digits and my hanger is about 45 min drive=
 over potentially slow highways. My adaptor is a highly modified device i go=
t from LeM.. what seems eons ago which is tapped for temp senders. Other sen=
ders will be direct contact thermocouples.
