Who needs this International 9800 cooling system manual
Heavy-truck technicians and fleet maintenance shops use this factory section to replace radiators, surge tanks and fan drives correctly and to torque fasteners to spec. It is written for trained professionals.
Before condemning a radiator or fan drive, the manual expects a proper pressure test and a check of the low-coolant sensor and site glass. Follow the coolant fill sequence exactly for your engine — Cummins ISM and ISX have different steps — and torque every mounting bolt to the values in the chart so the cooling package sits square and leak-free. Reusing damaged heat-shrink clamps or hoses is the fastest route to a repeat comeback.
