Got a call from my wife when I was out of town, saying that the temp gauge on the 05 rl was up to about 3/4, and car was running rough. Friend had her run heater full blast, and it took it right down to 1/2. My question: Is there a temperature threshold that would set any dash lights off as a warning? It ran at 3/4 for about 30 minutes. As a previous legend owner, I am sensitive to overheat/HG issues. Put power direct to both fans and AC Condenser fan was dead.
