What i have going on is there is exhaust pressure coming from the coolant hose that enters the exhaust manifold causing the coolant not to flow and pressurizing my coolant sys, engine overheated, my question is where should i start first, pull the manifold and have that fluxed, then pull the head and do the same, or is there a common problem that i do not know about when this situating happens, thanks for any suggestions,
