I have a zd331,5years old .just started having heating problems,every30-40minutes I blow out rad. And all surrounding areas,also wash down with hose in rad core,both sides. Help!!
Old golfer, Apply auto think to this. Check if thermostat is opening (it has one?), Gruck has plugged tubing? Collapsed hoses? Blocked fins? Bumping this active may get you some help.
