I believe my higher temps with bellows thermostat was due to higher pressure rad cap. Instructions said not over 4 psi for cap with bellows or it compresses bellows. I tested the temp sender and it is good. Decided on Installing a 160 newer version thermostat and see what it does. My temp runs just over 185 in 70 degree weather today in FL. Will see how it does and possibly add a plug with small hole later and test again. <div>Jim Henningsen <br><br><div id="AppleMailSignature" dir="ltr">Sent from my iPhone</div><div dir="ltr"><br>On Apr 19, 2019, at 2:48 PM, DAVID MASSEY <<a href="mailto:dave1massey@cs.com">dave1massey@cs.com</a>> wrote:<br><br></div><blockquote type="cite"><div dir="ltr"><font color="black" size="3" face="Arial, Helvetica, sans-serif">
