Thermostat Question

[Deep Dish V35]

The thermostat housing has 2 pipe fittings... one large one for the bottom rad hose, and one small one....

The original thermostat on mine didnt have the second pipe..... where as my replacement does. Can anyone tell me where this small pipe goes and where the other end is joined on their car? I currently just have it blanked off...

that pipe on mine goes across the front of the motor, and goes back to a fitting on the passenger side of the motor above the a/c pump.... a brass thing with two pipes... and the other pipe goes back behind the motor to, i think, the heater core

it is obviously the low temp bypass..... mine just feeds into a different location. I was thinking it should be joined into the thermostat so that it heats it up and opens the valve...

i think this pipe is definitely an issue, even though it looks factory the way it is....

Ive just installed my original housing, with the thermostat cut out, and the overheating problem has gone away....
