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!
