Temp gauge
Help been cleaning and just doing odd some stuff to my new panel. Question here temp gauge only works when it’s warm outside but the digital read out always works. What to change first? No check engine light.

The analog gauge is of little use. It is basically an idiot light; if you notice it is high it is too late.
However, you may be running too cool. The running temp should always be above 180F, if it is lower the t-stat has failed.

You might be just fine, but it’s a known fact the ECM looks for a certain time frame for the thermostat to open and keep the Dexcool regulated to 180 degrees.
If you get a CEL or MIL light have the code read , if it’s P0128, it’s the Duralast not meeting the ECM’s perameters. It’s just your HHR telling you to put in the right part not the cheaper parts!

If the AC works no codes and the digital read out works. What to change next? The bottom hose isn’t as hot as the top. The bottom one I can hold my hand all the way around it after 20 min drive and digital read out says 189.
