This LoneStar cooling system service manual, publication S12049, is the Navistar radiator and cooling package guide for International LoneStar trucks built with EPA 1998 federal emissions. It walks through removal and installation of the surge tank, A/C condenser, fan shroud, radiator fan, fan belt, fan drive assembly, radiator hoses and the full radiator assembly, with factory torque values. Procedures start at the hood and cooling package front and work back to the left and right stay rods, mount brackets and ground wire.

Torque targets include charge air cooler mount bolts at 70 to 80 N•m (52 to 59 lbf-ft), transmission oil cooler bolts at 108 to 135 N•m, and radiator mount bolts and nuts at 90 to 115 N•m (66 to 85 lbf-ft).
