Simplifying The Coolant System?

[robo]

That would work except that when stat is closed there is no where for the pumped water to go which is why its best to form a loop using what would have been to the heater matrix. The small pipe from the thermostat housing to the filler bottle is only there to keep the system purged while engine is running, on some of those purge pipes there used to be a small restrictor shoved up the end by the bottle to limit the amount of pump over ,its not big enough to act as a bypass . On the subject of extra pipes we have always used stainless steel and bought those samco silicone hoses, that way all the long runs are cheaper to do and look a lot better. If you havent got a beading tool stick to the plumbing sizes of the tube 15,22,38,35,42 mm and solder an olive on the end of the pipe to act as a bead, dont nick the wifes hoover or you will end up with ears like a cage fighter. hope this is of some help
