[. . . ] Servicing Engine coolant should be changed every 2 years or every 1000 hours, whichever comes first. When changing the engine coolant, the system should also be flushed to remove any contaminants left behind during draining. Following are recommended procedures for checking, draining, flushing, and filling the cooling system. Checking Coolant Level The coolant level should be checked at the overflow reservoir, located under the upper blower housing assembly. Unhook the retaining straps and remove the upper blower housing and screen assembly. Use equal parts of ethylene glycol and water only (distilled or deionized water is recommended). 10 Draining Cooling System 1. Unhook the four retaining straps, and remove the upper blower housing and screen assembly. Slowly loosen the radiator cap to the first stop and allow any pressure to bleed off. Carefully tip the bracket away from the reservoir, and lift the reservoir out between the bracket and fan. Pour out the contents of the reservoir and wash out or clean as required. Dispose of all the old coolant properly, according to local regulations. Figure 11. Locate and remove the coolant drain plug in the lower side of both cylinder heads. After the coolant has drained, apply pipe sealant with Teflon® (not Teflon® tape) to the threads and reinstall the plugs. The coolant overflow reservoir has 3 molded protrusions (1 upper, 2 lower, see Figure 14) that fit into corresponding holes in the support brackets. Reinstall the reservoir, engaging the two lower molded protrusions in the mounting holes of the support bracket. Hold it in this position and torque the screws to 7. 3 N·m (65 in. Fill the cooling system with clean water and a cooling system cleaner recommended for aluminum engines. Start and run the engine for five minutes, or until it reaches operating temperature.
