Coolant Flow Through Heater Core
Does coolant always flow through the heater core?
On my '81 there is a vacuum valve that controls the flow, but I do not see this on my '95. So I am assuming that there is always flow through the heater core and its just the air mix door that controls the hot or cold air flow out the interior vents.
Is this correct?
EDIT: Never mind, just found the answer; last sentence in the Heater System paragraph in the FSM.
