virden Posted August 30, 2015 Share Posted August 30, 2015 A radiator hose on my X/F burst the other day, and after replacing it I noticed the radiator gently steaming from a section of the core. I dried it out with compressed air and also left it for a couple of days, but once the rad gets hot a slight wisp of steam is visble. The car is othewise behaving normally. The rad is a beautiful aluminium example supplied by Redline some 6 yrs ago, and even when left for over 24hrs there are no discernable leaks of water, so it must be a hairline crack, only apparant when the system is pressurised so what is my best course of action, some rad weld or is taking it to a specialist OTT?

The_ASH Posted August 30, 2015 Share Posted August 30, 2015 Previous experiences with Radweld always point me towards repair or replacement... you know it makes sense. Link to comment Share on other sites More sharing options...
SM25T Posted August 30, 2015 Share Posted August 30, 2015 It would provide a temporary fix if you can't get to a repairer. Best is to remove radiator and take it to a decent repairer. Link to comment Share on other sites More sharing options...

thompster Posted August 31, 2015 Share Posted August 31, 2015 I used 'Bars Leaks' a few years ago with great successs. No doubt looked down upon but it worked well for me. Most motor factors sell it. Link to comment Share on other sites More sharing options...
Bob_r Posted August 31, 2015 Share Posted August 31, 2015 appreciate that radweld doesn't just confine itself to your radiator, it is only a temporary fix! fully flush the cooling syste once the radiator is properly sorted. Link to comment Share on other sites More sharing options...
revilla Posted August 31, 2015 Share Posted August 31, 2015 I have just finished stripping and cleaning an engine that had been treated with something like Barrs ... the effort it took to get the thick layer of coppery gungy deposits out of all the (already narrow) head waterways was enough to convince me that I will never allow the stuff near my engine, even if stranded by the side of the road.
