My bus overheat, why ?

Hi everybody !

So there is my problem of the day.

My bus overheat pretty easily, short uphill road, long ones, itís not cool.

Iíve clean the radiator with a air compressor, Iíve drained it and put new coolant, my fan seems working, but it still overheating.

My bus is a 1996 Internationnal, 3600 Vista, itís the short nose one.

I believe itís a Navistar

Any thought one what could it be ?

Have you checked the water pump? Is it weeping, and does it have any excess play?
Check your thermostats?

How's your transmission fluid look?
