Over heating

[Robert Leigh]

I recently had my Ulsteroid Special homemade radiator repaired; a lot of the soldered seams on the fabricated header tank had started to leak. My repairer obviously cleaned it all out properly because it is running at a considerably lower temperature than it was, so I have two good results. Because running temperature had increased previously I had considered using a pressure hose into the cylinder head connection to see if anything was washed out from the block by this means, so although I did not have to do this I offer it as a suggestion. Thermosyphon circulation has not got enough oomph to shift the muck.
