I changed mine so it's more like the ecotec cooling system. The heater has a 4hose heater tap so it's also a bypass even when the heater is off. the ecotec's heat up quicker and also it makes the cooling system more efficient. (how you ask) well, once the cooling system is up to temp and the thermostat is open you need all the coolant going through the radiator so that it can be cooled. With the bypass a certain amount of coolant (which is still hot) is cycling back directly through the water pump straight back into the engine block without been cooled.
Been running it like that for about 2 years now with no noticeable problems. Engine heats up quicker on cold mornings (and we get a fair few of those here in NZ) so the demister works better.
