Kubota Thermo Syphon Cooling question

[njrqs]

I just flush them with the garden hose.

I also revserse flush them (eg. from the bottom). I have heard this cam dislodge scale etc. which can further clog the passages, but I have never had a problem doing this.

If it is real bad you'll have to take it in and get it rodded out.

Cheers
