“ I assumed the thermo would pull them if working.”

The thermostat expands when hot - releasing tension on the cable - allows flaps to open. This is a fail safe - if the cable breaks - the flaps default open.

Double check against diagram above

If the thermostat is malfunctioning, it will cause the oil temp to climb rapidly.

Raise the car up, and with it not running, take a heat gun and warm up the thermostat. You should see it expand and the flaps move to the open position. It's real easy to get the arm or the spring installed incorrectly making the flaps not work right.

If your thermostat is bad, and you hooked up the cable with the thermostat expanded, your flaps will be held closed (not good). If that is the case, disconnect the cable from the flaps and see if the flaps can be moved by hand. If they can then you need a new thermostat.

Hi Clay,
I have the spring disconnected and have been pushing the flaps back towards the firewall (what I call up) , when I checked they were pointing towards the rear of the car (what I call down) so that is probably why I overheated . This is something else on my list I need to get fixed.
Thanks
