92 temperature cycles

If it stays in the normal range while it's cycling, what is the problem?
If you are sure the Tstat has the correct temp limit, you may not have any
problem at all. Sounds like it is opening and closing just like it should
when the engine begins to heat up to the stat limit. My 91 typically runs
on the cool end of the gauge...only rises to mid-point if I climb a long
hill like yours at highway speed.
