I have a 2017 ATS 2.0 and its shaking on engine startup. I had the dealership replace the PCV hose fill the coolant and replaced the spark plugs. Cleared codes and now after a couple days the rough idle cold start returned. Popped the hood and I notice the coolant tank is fully empty. so I started to look for more cracked hoses and think I found the issue. I see the "Upper radiator hose" (PN: 22908202) is not attached to the radiator. It is freely loose. I check and see why appears the nipple connector is broken off. I am hoping the radiator does not have to be replaced now. I attached photos of the broken nipple and the hose with half still inserted. I dont see another way the new hose can be connected to the radiator. Any help/advice is much appreciated.
