dont panic mate as long as the head gasket is in good condition,all the hoses need replacing eventually.my vr6 burst a hose after a week of having it then another 3 went in the following month, the mechanic said i might need a new head gasket cause of the over heating , i put some chemi weld compond in havent had any problems since, make sure theres air lock , turn your car on take the lid off run the car to temprature , will get the air lock out
