But the temp climbs to 210 pretty quick the fan pulls it down to 200 shuts off and climbs right back up to 210 again in no time. Oil temp will get up to 235 if pulling up a longer grade. I've been blaming it on the hot weather. Is it common for a ISX operating temperature to climb quickly?
Isx 485 in a 579 Pete not modified about 720 000mi, I've put about 65 000mi on it. I realize the modern engines put a lot more demand on cooling system just seem like it might be abnormal.

Maybe its time for the A/C and CAC units to be moved aside .. them and the radiator elements all cleaned out / acid (radiator coil cleaner) washed??
