is near empty.<o:p></o:p></span></p>

able to hear the stock voltage regulator ticking away..<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">My temp gauge is reading about 25 degrees high. I noticed it after a shop installed a new clutch, which required the engine to be removed, coolant drained, etc., but nothing that
should have affected how the gauge reads. Running on a cool day, temps were reading around 215-220 degrees. To ensure I wasn’t actually in danger of overheating, I checked various water-cooled locations with an infrared thermometer. Highest reading was
right at the water neck/thermostat housing (191 deg F). The fuel gauge is reading accurately. I understand the under-dash instrument stabilizer can affect both instruments, but in this case, only one gauge is off. I plan to check the ground to the temp
gauge and clean contact points at the engine sending unit and at the gauge. Any other suggestions?
