Default Re: Air cleaner "Auto Therm" unit

Four more pics. I had to bend the retainer quite a ways to get the good one out-pic1.

The good one and the bad one-pic2.

Pic 3 and 4 show the stroke of the diaphragm from closed to open.

That's where I'm at right now. I will try to get the swap done after work tomorrow. I hope this may help anyone that wants to do this repair on their later V-6 engines.
