What is the gauge reading( just wondering)

First have you fixed all the leaks? Cause if there's air in the system your not going to get any hot air.

if your blowing rad hoses sounds like your rad cap is stuck, rad cap regulates pressure. You should never get enough pressure to blow a line if the cap is opening

i fixed the leaks and it was working for 2 weeks then i was just sitting at an idle and i blew another hose this is starting to get bad. brian v8 its a stock rad cap would that cause all the hoses bursting
