Hi all, I was a forum member some time ago, but couldn't ( not savvy enough to ) retrieve my password etc, so rejoined as p3man451 - I have a 1948 Export P3 4 light " 75 " . I reside in the frozen wastelands known to it's occupants as County Durham. Done 10 miles ( when it was very evident that all was not well in the cooling dept.) in the last 7 years - guess I've too many other interests. Headlining needs replacing and she ( Daisy ) probably needs a recored rad. I'm determined to have this car out of the garage this " Summer " and have already removed both inspection plates on the inlet side to verify what others have said about sludge. Upon removal, I had a scrape at what I thought was the bottom of the water jacket, but it looked too high , according to the sectioned drawing in RSR Workshop Manual. The screwdriver, much to my initial horror, went through this apparently solid floor ! Quite how this crust had formed is anybody's guess, but once removed and the sludge below it, I reckon I improved coolant capacity by 3 pints. Interesting to find some of the original casting sand in there too.
Next job is to attempt to loosen the crud build up in rad --any help on this would be fully appreciated. Some say caustic soda, others citric acid to leave in rad overnight.
I suppose I'm putting off the inevitable costly recore in hoping all will be well when I try it without a 'stat in the system. I'll be using seived rainwater for rad. Has anyone heard of "waterless coolant " and if so, has it worked and are there any drawbacks ?
Will post a pic of car when I work out how to do that. Best Regards, Alan
