FreedomCore Posted July 1, 2016 Share Posted July 1, 2016 So after fitting a civic half rad, my coolant hoses keep splitting. First it was one of the turbo pipes. So I changed both rad hoses and turbo hoses to dinner uprated ones. But now the hose going to the water pump has split. The previous radiator didn't hold any pressure which is why I swapped it out. Does anyone know if this is just the increase in pressure finding weak spots or is it something else?

lukEp Posted July 1, 2016 Share Posted July 1, 2016 (edited) Could be there's a problem. You old rad could of been the first week spot. Now you've swapped it out the next week spot will be hoses. Maybe headgasket, have a combustion leak test done. Edited July 1, 2016 by lukEp Quote Link to post Share on other sites
FreedomCore Posted July 1, 2016 Author Share Posted July 1, 2016 Cheers, I'll look into it. I just don't want to keep changing the hoses if there is an underlying problem Sent from my Nexus 6P using Tapatalk Quote Link to post Share on other sites
lukEp Posted July 1, 2016 Share Posted July 1, 2016 Could just be the age of the cooling system as they are close to 20year old hoses now, but could be an underlying issue which is over pressurising the system and splitting 20year old rubber. Quote Link to post Share on other sites
Bug679 Posted July 28, 2016 Share Posted July 28, 2016 Have my half rad a few months now and about a month ago split a turbo water pipe and blew the hose on back of the engine off then two days ago blew the one off where the thermostat goes. What half rad you got man ? I put mine down to weak Spring clamps that's 20 years old and put on t bolt clamps 😝 What would cause the system to over pressurise ? Sorry for hi jacking lol sorta same shit happening doh 🤔 Freaky 😂 Quote Link to post Share on other sites
richardc9052 Posted July 28, 2016 Share Posted July 28, 2016 Rad cap is supposed to release excess pressure. Quote Link to post Share on other sites
FreedomCore Posted July 28, 2016 Author Share Posted July 28, 2016 The cap in my previous rad had failed and held nothing. Just instantly overflowed. Touch wood, it all seems to be holding nicely now with the new half rad and hoses. Sent from my Nexus 6P using Tapatalk Quote Link to post Share on other sites
dan106 Posted July 28, 2016 Share Posted July 28, 2016 That's weird bug those first too are exactly the same that blew on daves car. Richard, we know that aha, the crappy rad that was in it before vented pressure as soon as you left it running after driving, it was fucked lol Sent from my iPhone using Tapatalk Quote Link to post Share on other sites
StuDoc 72 Posted July 29, 2016 Share Posted July 29, 2016 Those pipes go first because they are the ones that are exposed to the most extreme conditions ( closest to engine heat and oil which weakens them ) Quote Link to post Share on other sites
