I'm more worried about the 100C + spikes these engines seem to have in hot weather and slow traffic. I've read too many blown head gaskets and overheating stories to allow my engine to get into that that temperature range. If the temperature was getting stuck at or below 60C, then I would worry about engine wear.

Thanks, Justin. Your explanation is convincing to me. There must be a reason that people make 79 thermostat.

I just post another thread on ABS malfunction indicator. Go check and share if you have any thoughts.
