Toyota 3.4 Thermostat Jiggle Valve at Charles Porras blog

Toyota 3.4 Thermostat Jiggle Valve. But what is still hard to understand is why the position of the jiggle valve makes such a big difference. As you can see, the jiggle valve is positioned straight down (6 o'clock position) which doesn't allow for trapped air to bypass the thermostat. The coolant will run warmer with the jiggle valve at the 12 o'clock position which is about 204°f to 210°f vs 190°f to 198°f with the jiggle. I see peeps saying that the thermostat orientation of the jiggle valve being at 12 o'clock instead of 6 causes this. Or, maybe the jiggle valve orientation itself has no effect on the operation of the system. This creates a air pocket in the cooling. Removed the thermostat housing, found the jiggle valve at 12 o'clock (last replaced by a toyota dealer during a t belt change btw), turned. This subject really gets me thinking.maybe that little jiggle valve is like the jiggle valves on grandmas old pressure cooker.with it down and. Maybe the temp sensing wax pellet in the stat. Is it possible the coolant piping leading.
