hotter than usual rear engine cat3116
just got a repowered 90 tc2000 all american reaer engine with a cat3116 engine. the first drive in it was about 35 miles, ran smooth til i had to jockey into a small parking spot. then it seemed to at the upper end of the temp range. both trans and engine temp. should i do a coolant flush and how would i do one, dawn detergent and a ton of water. maybe my radiator has some blockage, how would i know ir thermometer.
any onw have a good resource for the all american? any one near taos nm?
