Bongo Fury

Hi folks. I've come to the conclusion that my thermostat is knackered, so will obviously need replacing. While i'm doing this, i'm wondering if it's possible to clean out the header tank, cos I can't see through it. I have to shine a small torch behind it to check the level. Any ideas?

Regards

Dishwasher .. ?? handy for M/Bike parts ....

Have heard about washing powder and rice with vigorous shaking or bleach for an hour or 2

caustic with the house type pebble dash (canterbury spa i believe) mixed in to scratch the crud out works for me.
use small chippings though as the gaps in the baffles are quite small .

check the outside/underside for stress cracks while its out.

Or you could !!!! Fit a low coolant alarm and never need to visually check the level ever again...
