Premis, thanks for the write up. I notice mine not coming to operating temp anymore. And it comes up slowly.
What is the stock thermostat temps??
180 and 188, replace them both at the same time.
One is long the other is short. Note which was in which location and replace the same. It is foolproof though, the long one will not fit in the short location.
