Hello All,
I noticed
water leaking out of the
heat exchanger which i put down to a faulty radiator cap which i replaced.This did not stop the leak and on closer
inspection I have discovered a hairline crack at the base of the flange were the mild
steel meets the cast iron {BOWMAN HEAT EXCHANGER} . The correct thing to do would be to remove the
heat exchanger and get the base of the flange welded however removing the heat exchanger looks like a difficult job and one i have not done before and the fact that despite a global recession finding a Welder in
Sydney {especially a good one}is harder then finding a
marine refrigeration mechanic ! just about impossible,plus I need to move out of this marina as it is costing too much.
My question is has anyone had any experience with a product called JB WELD a cold welding product that can withstand heat up to 500c or has anyone got any ideas of how i could fix this hairline crack without removing the Heat exchanger.Failing all that how hard is it to remove and replace.
As always would appreciate any advise.
