Ronnie Posted October 12, 2009 Share Posted October 12, 2009 Cooling fans may not be a problem. The engine has to get up to about 230 for the fans to run. You can manually turn them on to test them on the diagnostics screen. Do they come on when you turn on the AC?I would start another thread about the radio to make this problem easier to follow.

rjfranken Posted October 13, 2009 Share Posted October 13, 2009 I've seen 210 degrees on some other older 3.8 Buick's when the fan starts at low, no AC. Link to comment Share on other sites More sharing options...
padgett Posted October 13, 2009 Share Posted October 13, 2009 Why mine are reprogramed. 180 thermostat. LO fan on at 185 off at 181, HI on at 189 off at 185. See excursions only at low speeds. Was 10F higher with bra so removed. It works for me. Link to comment Share on other sites More sharing options...
