Thermostat Questions Options

[orbit398]

Putting my engine back together and have a few questions on the thermostat. I did the check to make sure it grows to the proper length (1.81" at 150 -160 degree water) and it seems close enough. Air flappers all operate fine, accept I think there is a little interference with the drivers side flap. If I try to close the flap all the way, it appears to hit a small piece on the aluminum large air bracket. See pics. I can't shift that flapper door down the bar a bit allowing it to clear this small piece of aluminum sticking out. I can modify the flapper a bit so it'd close all the way but figured I'd ask folks.

Next Question, are there instructions on how to adjust the cable operation of the air flappers. I assume I need to pull the thermostat to it's extended length and secure the small cable to the flapper bar location at that cable length. The result being that when the thermostat is extended, the cable should allow the flapper bar spring to fully open the air flappers.

thanks for any advice

I always got the car to operating temp (or close to it), then loosened the clamp that holds the wire, let the flaps go to full open, and then tightened the clamp on the wire. The "cold" position falls wherever it wants at that point, but you're sure that the "warm" position is correct, or as correct as you can get it.
