<html><head><style type='text/css'>p { margin: 0; }</style></head><body><div style='font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000'>Hi all,<div><br>Thanks again for all the good suggestions. </div><div>The lower rad hose coil is a must. The previous one had become pretty sketchy even prior to the engine replacement so I had already replaced the coil with some 1/16" stainless welding rod wound in a coil. Next time around I'll source a whole new hose and make sure it includes the coil (some hoses don't...)</div><div>As I noted yesterday I replaced the 180 with a 160 thermostat and checked both of them in a pan... dunno about absolute temps (as noted by Stu, IR thermometers are sensitive to what material they're reading and I haven't gone and checked the IR emissivity of water) but the 180 was definitely opening way later.</div><div>Darrell's note about air pockets led me to make and put an air bleed fitting in the water heater inlet hose. And using that, I discovered that my heater valve actually doesn't flow anything when it's only half open... the heater was still dry.</div><div><br></div><div>So with all this new technology it now steadies out at 180 on the gauge even after exploring the power band a little more extensively (should have put the IR thermometer on it but that slipped my mind). Very promising stuff!</div><div><br></div><div>Cheers and hopefully I'll see some of you next weekend,</div><div>Theo</div><div><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><br></div></div></div></body></html>
