New pipe for heater

Rebuilding the engine I decided to correct one of the design flaws... .

The copper pipe for the heater is mounted under 2 head nuts. To remove it (for exchange thermostat for example) means unscrewing these nuts.. Unscrewing only these two does not seems to be a good idea. And I was still not sure about the leakage of the thermostat cover, but did not want to have to undo the head nuts again...

So I made a new copper pipe, fitted at the bracket for the alternator. I'm happy with the result.

Old and new:

Made a small (temporary) improvement with an additional bracket on the thermostat housing. Will sider it properly in near future, when the coolant must be drained for fitting a temp sensor.
