Afternoon all.

Was driving home yesterday, only a short journey, when I got a whiff of a blown head gasket. Poor sods I thought then I noticed a bit of smoke billowing up from under my bonnet. To say my arse nearly fell out is an understatement! Checked my instrument cluster, all ok, temp normal, no warning lights, still running and driving fine so I poodled home which was under a mile. Lifted the bonnet close to tears when I spot the top hose from the rad to the block has a tiny hole in it and is squirting water onto my engine which is running down and burning on the bottom (manifold?). Anyway much to my relief I've ordered some new Samco's to replace the offending hose and was wondering.....

Will I need to bleed the system just to replace the top rad hose? Thanks in advance and Appologies for the long winded post. Stu.
