The radiator on my MKIV has given up for the second time. I had it repaired once, and it lasted about a year. It is at the repair shop now being repaired again. It seems it always springs a leak at the bottom of the core where it meets the tank on the left side. I have it mounted with a piano hinge at the top and the Breeze mount at the bottom. This seems to be the generally accepted way of mounting. Not sure of why this is reoccurring, weather this is a mounting issue or a radiator quality issue. Curious as to other radiator failures and remedies to fix this problem. I am going to mount the piano hinge with a strip of 1/4 x2" rubber at the top this time in attempts to reduce vibration. Any thoughts are appreciated.
