Check for the presence of any air pockets in the cooling system. If there are air pockets, it may misrepresent the coolant level -- and maybe more coolant is needed. Other than that, hands on testing is needed. No way to know why the light is coming on without testing it hands on. www.repairpal.com/repair-shops
