I'm certainly not an expert by any stretch but I did research this prior to
installing the 180 t-stat. I found out from the DML the magnum engine computer
wants to see a temperature range between 175 to 205 with 182 being the best
temperature. Above or below this range will trigger an engine code and the
Service Engine light. Replacing the stock t-stat with the 180 keeps the engine
within it's optimum range while also helping to keep it cooler. A cooler engine
will produce more HP and reduce pinging.
