Cooling System Filling

First clean system to remove old glycol, see Cooling System Cleaning.
Fill system with 50/50 glycol/water mix.
Continue filling system until full, this provides better heater performance. Be careful not to spill coolant on drive belts or the generator.
Fill coolant reserve/recovery system to at least the FULL HOT mark with 50/50 solution. It may be necessary to add coolant to the reserve/recovery container after three or four warm-up/cool down cycles to maintain coolant level between the FULL HOT and ADD marks; if any trapped air was removed from the system.
