OK - here's the scoop
2000 Cherokee, 63k miles - upgraded to the 3-row brass/copper radiator from radiators.com (CSF brand) - flushed the cooling system, new robertshaw hi-flow thermostat (195), new hoses, new fan clutch, added a seperate tranny cooler. The new fan clutch is fine, and the aux fan works fine - the system has been sufficiently burped, and has a mix of 50/50 distilled water & antifreeze, plus a bottle of Redline's Water Wetter. (Yes, I'm anal! )
Well, running down the highway, it's running just under 210 (about the width of the gauge needle) - in town, particularly sitting, but if running at 30mph or lower, it runs over 210 (again, about the width of the gauge needle) - once it gets there, it takes a quite a bit to come back down under 210. The aux fan will come on (even with the A/C off) when idling, so it's doing it's job ...
I've went back with an infrared heat gun and checked a few areas. The thermostat outlet is about 225, as is the inlet side of the radiator - (when the needle is reading just over 210) - isn't that a bit on the hot side? I've seen it get upwards of 230 ...
Any advice, or is this normal? (BTW - I have searched - haven't found anyone who has checked with the infrared gun, which is what I'm hoping to have answered here ... )
