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?
thanks
adam

Could be the radiator. Could be fan malfunction. What type of fan system do you have? Hydraulic? Electric? Was the fan spinning fast when the temp was high?

looks like hydraulic. was never spinning very fast. actually after that run it looked as though my coolant overflow was mirky. head gasket? sure hope nor. kina looked like oil and water mixing. would a local mechancic be able to analyze a sample of coolant?

If its murky, the radiator could be clogged. I would think any mechanic that has coolant testing equipment could easily do a test for oil in the coolant. Just because its murky does not mean there is oil in it.

I would start with a complete coolant flush. I believe if the temp was pretty high, the fan should be running full blast.

AH yes the rear engine heating issue. We know it well. My advise, first find a pressure washer, and blast the heck out of the radiator. Next do a coolant flush and fill, next get a thermostat... they are a pain to seal. Get all new gaskets. I had the same issues with my international- all better now. Just took a while finding the problem.
