Steam powered SV - Radiator crack
 

Out on the bike t'other day car in front threw a stone at me. Saw it comming, cringed, loud bang. Stopped and checked for damage and couldn't see anything.

Got home and there way a bit of steam from the front, it was raining so could have been due to that.

Dry today & on way home stopped at some lights and was engulfed in a steamy cloud. There is a very small leak in the rad just near the bottom next to a dent where this rock must have hit.

Has anybody used rad weld to fix a leaky bike rad? Holts site mentions not to use on Rover 825 due to the small capillaries used, thought it was only active in contact with air :?

Yeah I've used it twice on the same radiator with brilliant results (second time I'd put a wheel through it). However a lot of people have moaned at me that it'll wreck the engine etc etc (same capillaries reasoning). Worth double checking with someone clever ...but I would.

Is the hole in the header tank or one ( or more ) of the tubes?

Re: Steam powered SV - Radiator crack
 

As far as I can make out its just one of the tubes.

Better to try soldering out the hole

My dads companies was a place in Preston doing repairs to rads and heat exchangers, but it is a damm long time since I replaced a core etc. where it was only a single tube, we would remove the tanks and solder out the ends of the tube. But I guess this is not practical on an SV rad.

Get some good strong sulphuric acid to clean round the hole (wear gloves/goggles) before applying a blob of plumbers solder.

All fixed :) Blow torch and a bit of solder. All back together just in time for it to start percipitating down. :smt092
