stranga3781 Posted October 14, 2008 Report Share Posted October 14, 2008 I replaced the reserve tank on my 99 deville and in the process I took the battery out. When I replaced the tank my coolant temp is a lot higher than normal. It stays around 190 and higher. Is there anyway I can reset the temperature gauge so that my level is normal again. At one point when I first changed the reserve tank my temperature read 266 degrees. I need some help. Link to comment Share on other sites More sharing options...
