Replacing Mini Fuses The mini fuses are intended to protect the electrical system. If any of them have blown out, be sure to pinpoint the cause. 1. Disconnect the negative battery cable. 2. Open the mini fuse box cover. See Figure 5-22. Figure 5-22 3. Pull out the mini fuse. 4. Insert a new mini fuse into the box. 5. Close the mini fuse box cover. 6. Re-connect the negative battery cable. Changing the Front & Rear Axle Case Oil See your authorized service dealer to have the axle case oil changed. Changing the Brake Fluid See your authorized service dealer to have the brake fluid changed. Replacing Radiator Hose See your authorized service dealer to have the radiator hose changed. Replacing Fuel Hose See your authorized service dealer to have the fuel hose changed. Replacing Brake Master Cylinder See your authorized service dealer to have the brake master cylinder changed. Replacing Front Brake Seal See your authorized service dealer to have the front brake seal changed. Replacing Rear Brake Cylinder Seal See your authorized service dealer to have the rear brake seal changed. Replacing Intake Air Line See your authorized service dealer to have the air intake line changed. Replacing Brake Hose See your authorized service dealer to have the brake hoses changed. Flushing the Coolant System & Changing Coolant CAUTION Do not remove radiator cap while coolant is hot . When cool slowly rotate to the first stop and allow sufficient time for excess pressure to escape removing the cap completely. 1. Stop the engine and let it cool down. 2. To drain the coolant, open the radiator drain plug and remove radiator cap. The radiator cap must be removed to completely drain the coolant. 18 Section 5 - Product Care 3. After all coolant is drained, close the drain plug. Note: Do not start engine without coolant. 4. Fill with clean water and cooling system cleaner. 5. Follow directions of the cleaner container. 6. After flushing, fill with clean water and antifreeze until the coolant level is just below the radiator cap. Note: When the anti-freeze is mixed with water, the antifreeze mixing ratio must be 50-50. See the Anti-Freeze section on this page. 7. Install the radiator cap securely. If the cap is loose or improperly fitted, water may leak out and the engine could overheat. 8. Fill with fresh water/antifreeze up to the "FULL" mark on the recovery tank. See Figure 5-12. 9. Start and operate the engine for few minutes. 10. Stop the engine and let cool. 11. Check coolant level of recovery tank and coolant if necessary. 12. Burp (remove air from) the coolant system as instructed in the Burping (Removing Air From) the Coolant System section on this page. Anti-Freeze WARNING When using antifreeze, put on some protection such as rubber gloves.(Antifreeze contains poison.) If you should drink antifreeze, throw up at once and seek medical attention. If antifreeze comes in contact with the skin or clothing, wash it off immediately. Do not mix different types of Antifreeze. The mixture can produce a chemical reaction between substances. Antifreeze is extremely flammable and explosive under certain conditions. Keep fire away from antifreeze. Keep children away from antifreeze. When draining fluids from the engine, place some container underneath the engine body. Do not pour waste onto the grounds, down a drain or into any water source. Also, observe the relevant environmental protection regulations when disposing of antifreeze. If it freezes, coolant can damage the cylinders and radiator. If the ambient temperature falls below 0°C (32°F) or before a long-term storage, let out coolant completely, or mix fresh water with longlife coolant and fill the radiator and recovery tank with the mixture. 1. Long-life coolant comes in several types. Use an ethylene glycol (EG) type for this engine. 2. Before employing long-life coolant-mixed cooling water, fill the radiator with fresh water and empty it again. 3. Repeat this procedure two or three times to clean up the inside. 4. Mix the long-life coolant. 5. The procedure for the mixing of water and antifreeze differs according to the make of the antifreeze and the ambient temperature. Refer to SEA J1034 standard, more specifically also to SAE J814c. 6. Add the long-life coolant. 7. If there is a mixture leak, add the long-life coolant of the same manufacturer and type in the same mixture percentage. Note: Never mix long-life coolant of different manufacturer. (Different brands may have different additive components, and the engine may fail to perform as specified.) 8. When the long-life coolant is mixed, do not employ any radiator cleaning agent. The long-life coolant contains anticorrosive agent. If mixed with the cleaning agent, sludge may build up, adversely affecting the engine parts. 9. The utility vehicle's genuine long-life coolant has a service life of 2 years. Be sure to change the coolant every 2 years. 10. Burp (remove air from) the coolant system as instructed in the Burping (Removing Air From) the Coolant System section on this page. Burping (Removing Air From ) the Coolant System To "burp" the coolant system, proceed as follows: Note: When re-filling the coolant system, this procedure should be performed every time to avoid an overheating risk. 1. Chock the rear wheel, engage the parking brake place the shift lever in neutral or park and jack up the front of the utility vehicle approximately 6". 2. Remove the bleeder screw (a) on the radiator, fill the radiator and when fluid begins to come out of the bleeder screw hole, replace the bleeder screw (a). The bleeder screw (a) can be accessed via the front right wheel well. See Figure 5-23. (a) Figure 5-23 3. Start the utility vehicle and let it idle. 4. Remove the second bleeder screw (a) where the radiator hose (b) connects to the engine and let the engine run until a steady stream of fluid comes out of the bleeder screw (a) hole indicating there are no more air pockets in the coolant system. Replace the bleeder screw (a). See Figure 5-24. (a) (b) Figure 5-24 5. Top off the radiator and replace the radiator cap. Then lower the front of the utility vehicle off the jack.
