hi, yes the spring is pointing out, BUT i mean the small "weep" hole that is next to the actual opening plunger, i believe designed to let a small trickle constantly run through so as not to completly shut off water to the cylinder head. i know on the smaller chryslers it is in the rim of the stat, but on the bigger ones it is a small depression next to the plunger.

On those early Force engines, the thermostat can only fit with the spring out--Which I thought was stupid because that way the expansion element is on the side with no water flow.


The weep hole, actually a Vee notch in the frame, can go in any direction but I usually orient it up. It does provide a small amount of water flow to heat the expanding element. When in the up position, the water will definitely run down over the element.
