Why does the throttle body on my '90 Ford LTD Crown Vic need coolant connections
There are 2 cooling water connections &
hoses (1x in, 1x out) on the intake
manifold/throttle body of my 1990 Ford
LTD Crown Victoria (5.0 l V-8). I don't
understand the purpose of this feature!
Especially in winter time, when the engine
is rather cold in the bginning, it takes quite
a while until the coolant gets hot and can
accelerate the warm-up of the engine by
heating up the intake air. But once it has
reached its operating temperature, pre-
warming is not required/desired any more.
Means: when heat is needed, it's not yet
available - and when heat is available, it's
not needed any more. So what happens
when coolant hoses will be disconnected?
Thanks a lot for clarification!
