My recent acquisition being a Humber of 1928 vintage developed a slight leak from a radiator hose. In the process of replacing the hoses at the moment, however upon removal of ol dhoses it is evident that a large amount of sludge and crud must be partially blocking the waterways. Looking at using one of the radiator flushing addictive, am I inviting further problems by doing this? They say the good ones are non acidic so perhaps nothing to worry over?
Comments and advise please.
The water coolant system is thermo siphon.

However, when I rebuild a Healey 100 engine, I pulled the core plugs, stood the bare block on one end and with a 1.4" bore piece of plastic pipe 'jet washed' into the bottom of the water jacket.
Handfuls of crud came out, and a little bit of casting sand! Engine then ran a good 10 degrees cooler, so its well worth doing.
I've had good success just using plain water from a hosepipe, flushing the whole system one way then the other repeatedly until the water ran perfectly clear. Didn't use any additives to do so.
While there is the "might dislodge the crud that's keeping it sealed" argument, I'm of the opinion that I'd rather find out the cooling system is ropey then and there rather than in the middle of nowhere on a hot summer day.
Plus you've not got a water pump to worry about, so there's no risk of clogging that with whatever is being sluiced about.
