TM 9-2350-311-34-1 10-1 WINTERIZATION KIT INSTALLATION — CONTINUED a. Installation — Continued 79 80 81 82 83 84 85 Place exhaust grille tarpaulin (178) holddown strip (179) on grille to serve as template. Locate hole at front of grille and tap six 5/16-24 UNF-28 holes. Locate five loop-type fasteners (180) and weld into position (TM 9-237). Remove four screws (181), install exhaust grille tarpaulin (178) with straps (1 82) up and webbing down, and install five screws (183) and five flat washers (184). Secure exhaust grille tarpaulin (178) by attaching five straps (182) to five loop-type fasteners (180). Before starting engine, unfasten five straps (182) to secure exhaust grille tarpaulin (178). Roil tarpaulin into smallest possible tube form. Secure with three webbing assemblies (185). Unfasten 4, 6, 8, or 10 straps as required. Roil air intake grille tarpaulin (173) inward to smallest possible tube and secure with 3 webbing assemblies (186). Winterization kit installation is now complete; refer to TM9-2350-311 -10 for operating instructions. Kit operation is intended to commence upon engine shutdown after engine temperatures reach normal operating levels. Operation of this kit with engine coolant temperatures less than 0°F (17.8°C) may result in failure of coolant heater. b. Bleeding Winterization System Coolant is hazardous waste and must be disposed of in accordance with local procedures or direction of the local Hazardous Waste Management office. 1 Disconnect kit coolant hose at elbow on engine-bank right coolant manifold. 2 Temporarily plug elbow, place disconnected coolant hose end in suitable container, and fill radiator (TM 9- 2350-311-10). NOTE Do not overdrain coolant system. Return drained coolant to radiator as required, then continue air bleed procedure. Air bleed should always be performed after removal or replacement of coolant heater or any coolant line. 3 Start engine and run for short period of time, observing flow of air and coolant out of disconnected hose. Continuous flow of coolant without air bubbles indicates air bleed accomplished. 10-22
