Generator maintenace problem
Problem: Unable to completely drain coolant. We have a 7.5 Onan which has been recently serviced - we tried to drain the coolant to change but cannot get it to drain. We put radiator cleaner in to flush the system but now the generator will not start. Troubleshooting indicates a code of 3 flashes, pause, three quick blinks. This correlates to high coolant temperatures... What can we do to drain the system. It ran fine after service but then starts to run for a few minutes and quits.1.8KViews0likes4Comments
