A few days away on a short break has given me some time to think things over, particularly with regards to the radiator (leak).
I decided this morning to investigate a bit deeper and see if I could find that tiny leak. My plan was to use two of these rubber bungs:
I think I had them from many moons ago as part of a wine making kit or something - demijohn bungs?
So I stuffed those in top and bottom and filled the rad up with water - then waited...
After about 5-10 minutes I spotted this damp patch appearing on the core. To get a better look I removed all of the cooling fins in that area - most of them were shot to bits anyway to be honest. Lets call it weight saving
And there seemed to be what I convinced myself a tiny hole about in line on one side of the 'flat' just about in line the point of my finger nail is. By the way, at this point I had moved the rad onto its side - in case anyone says "but water doesn't run uphill"
So off I went to find some weapons:
A few minutes later and we have this:
I appreciate that the some of cooling fins are knackered, but hey, if it holds water, I cant see that being a massive problem...
So now I am off outside again to refit the rubber bungs and see if it has sealed.
