Good to hear it’s running well (even better by the sounds of it) again, Alan! :D

the new pistons are of Australian manufacturer JP,
I rebuilt a Talbot Sunbeam a few years ago and the only source I could find for OS pistons were JP, decent quality and price. :wink:

Hello Folks,
Not updated for quite some time, we took the Bullnose up to Keswick early November on the trailer to marshal on the VSCC Lakeland trial and the car behaved itself, well we decided with the car always running hot to install a small 12 v pump to circulate water, (normally natural syphon arrangement), I had read about this sometime ago in the Bullnose Magazine, so pump, and return bottom engine water flange purchased, John (brother) and I set about the modification, John took the flange home, drilled 15mm hole to accept short piece of copper pipe as can be seen in the pictures, we needed to extend the pipe into the engine so as not to cause a short circuit, with a few slight mods we removed the radiator and commenced the installation, after a couple of hours the radiator was refitted and at the water drain point on the radiator we fitted a tee piece to connect to the pump as shown.
We have not tested as yet on the road, but when the pump is switched on, the water in the head tank of the radiator can be seen circulating.
I will update after test runs.
Regards
Alan

Just out of interest...
I presume the pump runs in the same direction as the siphon flow (out of the bottom of the radiator and into the engine?) to boost the flow a little, or is there some magic involved? Will you run this with a manual switch or add a temperature switch?

Hi Phil,
Yes your correct, pump draw from the bottom of the radiator via drain tap modified, and then feeds through the modified lower flange 15mm pipe into the engine, there will be a slight reduction in the flow through the flange, but still allowing for the water to siphon as normal when the pump is not running, I have wired the pump through an illuminated on/off switch for the time being.

Alan
