This WorkStar cooling system service manual, publication S12036, is the 2010 International factory guide to the radiator and cooling package on WorkStar and TranStar trucks. It details removal and installation of every cooling component, from the grille and splash panels to the radiator, fan drive and charge air cooler, with the exact torque values a workshop needs. Each job follows the factory sequence of unlatching the hood, removing splash panels, and freeing the charge air cooler hoses and stay rods before the radiator fan or radiator itself can come out.

Applicable truck models
The procedures apply to WorkStar and TranStar vocational chassis. Note that the WorkStar radiator drain valve sits on the lower left side while the TranStar valve is on the lower right, so follow the figure that matches your truck. Torque figures are model-specific too: splash panel bolts pull to 9 to 12 N•m (80 to 106 lbf-in), power steering reservoir bolts to 56 to 68 N•m, and the TranStar radiator assembly mount bolts to 88 to 107 N•m (65 to 79 lbf-ft). Confirm build details against the manufacturer at the International Trucks website.
Who needs this WorkStar cooling system manual
Fleet technicians, radiator shops and owner-operators servicing the WorkStar cooling system will use S12036 for correct component sequencing and torque, and for the notes that flag when a cracked or contact-damaged fan must be replaced rather than reused.
