Hi Folks,

My M998 has been running perfectly for the last couple of weeks now. Today I started the vehicle up and drove it to the shop and during a run to pick up some lunch, I noticed the temp was pegged at 205 degrees. This truck runs at a consistent 180 degrees.

When I got home I popped open the hood, opened the resevoir and dropped a thermometer in. The water is flowing (t-stat not stuck) and the water didn't appear to boiling over. The highest reading I could get on the thermometer was 179.

Does this sound like a case of a faulty temp guage or is the water in the resevior not an accurate way to determine the true temp?

thanks,
Ron
