I have a coolant leak. It's on the exhaust side towards the back of the block. Are there any hoses or anything back there other than the head gasket that could leak coolant. All other fluids are fine.
Has anyone tried that head gasket leak sealer that you can get at autzone?

 

Helps to know what engine you have... If its a 1.8T then its the coolant flange on the back of the head. No coolant additive is going to fix this.

 

^^^ Yep, better change the whole flange.
