    I noticed today that my coolant temp was doing some wired things. I usually watch my temp on my cat I D. I can be pulling a hill loaded or empty and see the coolant temp raise to about 190*f and as I hit flat ground the temp will go down to about 181*f. This seems all good, but what I find weird is that when going down hill and just basically coasting the temp will drop to 176*f. On occasion it will go as low as 172*f. After you get to the bottom and give it power the temp will rise up fairly quick to about that 179 to 180 range. At idle well I am loading the temp will bounce between 177*f and 183*f. Maybe I am worrying about nothing but it seems to me that I don't remember such a drop in temp on the down hill before today. Is it possible that maybe one stat is sticking open or is this just something that I haven't caught before today? Oh ya ambiant temp was 28*f and little or no wind.

    That's really normal. Your stats could be getting a little lazy thou. I can't seem to get more then 3-4 years out of mine. They start doing exactly what yours is doing. Coasting going down along grade they take to long to shut resulting in temps under 180. If it starts to get worse throw some new stats in.
