I am not convinced that it IS running 230-250. If it was really that hot wouldn't it be puking out the rad or hard starting?
Rad is factory looks to be in good condition, recently serviced but do not know for sure, factory shroud, fan halfway into shroud, clutch fan.
Mechanical gauge is new...have both hooked up at same time. Both read same, machanical just a little slower to register.
Car pretty much shows slow climb to this temp weather sitting in shop or driving in town,or up to 45 -55 mph.
