Removal 1. Park machine on a level surface, lower cutting unit, stop engine, engage parking brake, and remove key from the ignition switch. 2. Open engine hood on the machine. CAUTION Do not open radiator cap or drain coolant if the radiator or engine is hot. Pressurized, hot coolant can escape and cause burns. Ethylene−glycol antifreeze is poisonous. Dispose of coolant properly, or store it in a properly labeled container away from children and pets. 3. Drain radiator into a suitable container using the radiator drain. The radiator drain is located near the left hand wing deck manifold (Fig. 9). 4. Disconnect hoses (upper and lower) from the radiator. 5. Remove air cleaner hose (item 47). 6. Disconnect reservoir hose (item 11) from the radiator vent tube. 7. Detach radiator shroud from the radiator by removing four flange head screws and flat washers. Position shroud away from radiator. 8. Remove flange head screws, flat washers, and lock nuts that secure the radiator to the support frame. Pull radiator from the machine. 9. Plug all radiator and hose openings to prevent contamination. Installation 1. Remove plugs from radiator and hoses placed during the removal procedure. 2. Position radiator to the support frame. Secure radiator to the support frame with lock nuts, flat washers, and flange head screws. 3. Attach radiator shroud to the radiator with flange screws and flat washers. Make sure that clearance between shroud and fan is at least .180” (4.6 mm) at all points. 4. Connect reservoir hose (item 11) to the radiator vent tube. 5. Connect hoses (upper and lower) to the radiator. 6. Reinstall air cleaner hose (item 47). 7. Make sure radiator drain is closed. Fill radiator with coolant (see Operator’s Manual). 8. Close and secure engine hood on the machine. 2 Figure 9 1. Radiator drain 2. LH wing deck manifold 1 Kubota Diesel Engine Groundsmaster 4100−D Page 3 − 13 Kubota Diesel Engine (Rev. A)
