If anyone knows the early kubotas they have what is called a Syphon Cooling system. This means as the engine heats up , Hot water rises to the top and the cooler water after the radiator sinks causing a circulation of water. I have fitted a coolant gauge and can see the temp in the top hose. This works but i think it can be improved upon. I have sourced a 12v electric water pump and plumbed it in replacement of the bottom hose. Currently I have run the engine and watched the temperature rise without the pump running. Turn the pump on and the temperature instantly falls . I have got a variable switch to adjust the pump speed if it over cools the engine . I will have to wait until i can run it hard under load to give a full test and report.

It was quite common for vehicles, both cars and tractors , and for that matter large bore domestic central heating , to operate on the siphonic principle. If your engine has a pressurised system ( spring loaded radiator or filling cap) the pressure raises the boiling point to allow the engine to operate more efficiently at a higher temperature than if it had a system open to atmospher. So unless your unpumped system was showing signs of boiling, it is quite possible that it was operating correctly . The presence of the pump’s impeller may well be having an adverse effect.

We replaced the battery and make up some new battery leads for the Estate Keeper. Joseph did the work, it took him a long time but he got it done

Just to let you all know the very sad news that Chris and Pam Suttons beloved Patterdale Terrier Lily passed away yesterday. She went to sleep in her favourite chair and did not wake up. I have just spoken to Chris and as you can imagine he is very upset I'm writing this with tears in my eyes as I'll miss my little mate R.I.P. Lily...

Thanks for your kind comments lads, it’s a tough time for me as I miss her so much.
