radiator leaking!

Post by muttley1 on Mon 08 Oct 2018, 3:48 pm

Hi,

came back from an hours ride the other day and tacky blue tinged fluid on boots and front of engine. If it smells like coolant, it is coolant.
I've a small leak on the lower end of the radiator. Its no problem to get it off, drained and ready to repair. Has anyone used radweld or the like? The leak is pretty small but maybe a new radiator is the way to go, bike is 1999, 41k. 

Cheers

I used K-seal many moons ago, it's not worth it. It sludges up the expansion pipe and makes a horrible mess.
When I replaced the rad, I had to put a coat hanger through the overflow pipe to hook the crap out, never again.

Thanks,

no to k seal then. I might well go for the bars leak stopper pellets. I can put enough in for the volume of coolant then rather than having to dump in a whole bottle of a liquid.

Its that or a new Chinese radiator for £70 or so, might as well do the hoses then etc etc. Hopefully problem solved for £4 or so.

The problem is that those "leak cures" clog up the water passages in the cylinder head and can result in damaging local overheating even if you then fit a new rad.

Hi,
I've ordered some bars pellets, that way I can only add what I need for the volume of coolant. Will drain the lot through too and see how it goes...
