250-500cc cooling system clean

hey fellow riders, is there a good cheap (or free if possible) way to clean out a cooling system to make sure theres no sludge build up in the channels in the cylinder and waterpump area, radiator is fairly clean and will have new hoses... I'm just wanting to make sure its all cleaned out properly 100% first, I had kinda thought maybe I could run a hose down through the head where radiator return pipes come out and let it flow out the waterpump possibly assisted with some product of some kind if needed.. but I'm not sure if that's even possible without damage or anything ?

50/50 distilled water & white vinegar run through engine for 5mins then let cool then straight distilled water run for 5mins then let cool then normal coolant. Good to go

ohh that's a interesting way lol, thanks i'll give that a try.. how good is it at breaking the shit down if theres any in there?

that's what i do to my coffee maker, you sure you have the right piece of equipment in mind

Haha yeah there was a thread on here years ago about it.

Vinegar is a mild acid I believe so works well but really unless ya bike has been sitting for a long time it shouldn't be too bad

where ever the info come from i'll give it a try as soon as I get my new rad cap and stuff sorted and get my head back together again lol
