Do what I do empty the system including a hose flush it out . Then fill it slowly ( INC ANTI FREEZE ) get it 1/2 TO 3/4 full and let the engine run a short while and grip each hose . Should feel almost the same !. If so top it up and give it a run . Watch out for the hot water when you take off the rad cap if all is OK .
PS .I put silicone hoses on a few years ago
