Although I've been towing for years, and have always had a transmission cooler on every tow vehicle, I can't remember whether the fluid should come from the trans thru the cooler then to the rad and o...

Don't think centrifugal vane water pump has a min flow. All the ones I've designed
in can go all day at zero flow (blocked)
Yes, burping is one, but not the biggie
Biggie is to keep the ICE from over heating on startup from cold
Gets a tiny bit to more (dependent on the hole size) flow from the ICE past the
thermostat so that it will open sooner than if no weep hole
Hottest area is typically around the CC and that is normally in the head...which
is insulated to the block by the gasket (of course gasket material factors)
By the time the CC heat brings everything up to temp...no weep hole will have the
thermostat NOT open till whatever thermostat range is designed in. They typically
do not just open/shut, but ramp (hysteresis) open/close
SMOG plays an ever larger component on how they design cooing systems today
