The old one I put in a pot and saw it open when I heated the water but It is still suspect. Here in the Phoenix area it is the rare day that we really need to be concerned with ambient temps leading to prolonged engine warm up conditions. Lately I had noticed that when running for prolonged times at Freeway speeds (+75 at 3500 RPM) the temps would quickly reach +230 and if I jumped off the Freeway and moved at surface Street speeds of 45 even with Stop and Go streetlights within a mile or two the temps had dropped back to between 210 and 220.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Should I look at using a 160 degree thermostat or just ditching one altogether?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><a href="http://www.microworks.net/"><span style='color:blue;text-decoration:none'><img border=0 width=191 height=80 id="Picture_x0020_1" src="cid:image001.jpg@01D87CBC.AA358640" alt=MWLOGO-Signature></span></a><o:p></o:p></p><p class=MsoNormal><b><span style='font-size:12.0pt'>Dave Riddle<o:p></o:p></span></b></p><p class=MsoNormal>Business IT Consulting<o:p></o:p></p><p class=MsoNormal>Office: 480-610-8234<o:p></o:p></p><p class=MsoNormal>eMail: <a href="mailto:dave@microworks.net"><span style='color:blue'>dave@microworks.net</span></a><o:p></o:p></p><p class=MsoNormal>Website: <a href="http://www.microworks.net/"><span style='color:blue'>http://www.microworks.net</span></a><o:p></o:p></p><p class=MsoNormal><a href="https://partner.microsoft.com/en-US/"><span style='color:windowtext;text-decoration:none'><img border=0 width=150 height=47 id="Picture_x0020_2" src="cid:image002.png@01D87CBC.AA358640" alt=Microsoft-Partner-Network></span></a><a href="https://www.acronis.com/en-us/"><span style='color:blue;text-decoration:none'><img border=0 width=150 height=63 id="Picture_x0020_3" src="cid:image003.png@01D87CBC.AA358640" alt="ace_1_orig"></span></a><a href="https://www.clio.com/"><span style='color:blue;text-decoration:none'><img border=0 width=200 height=61 id="Picture_x0020_4" src="cid:image004.png@01D87CBC.AA358640" alt=CCCLogo></span></a><a href="https://www.citycommunications.com/"><span style='color:windowtext;text-decoration:none'><img border=0 width=137 height=40 id="Picture_x0020_5" src="cid:image005.png@01D87CBC.AA358640" alt="cityhosted-authorized-dealer_orig"></span></a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
