Hello all. So the fettling progresses slowly on Pootle and we are now looking to improve cooling as she is running a bit hot. I have flushed out the system with Wynn's rad-flush but to be honest it didn't do too much and I think we really need to have the radiator re-cored to do the job properly. There is a good place for this near us in Cranleigh to do this but, before I get it done, has anyone tried fitting a bigger radiator? Looking at the one fitted it's 18" wide and 12" deep but there is a 3" gap below it so it could be 18" * 15" which would be a useful increase I think? I could perhaps fit a bigger radiator from some other vehicle or get this rad rebuilt with a longer core... Any views or experiences? Cheers Tony.
