    The problem is that temp fluctuations like that aren't normal and I'm afraid of overheating the fan clutch kicks on about 208

    Temp sounds normal to me. Flat roads mine will run 181-183. Climbing if it’s a decent sized climb it’ll go right to 210 and kick on the fan automatically. Normally I just turn the fan on manually around 190 or so. Even if I don’t catch it until 200 it’ll take a few seconds to reverse the temp.
