Coolant Flushing

[ozonehostile]

As it happens I decided to flush it through using the running engine method instead of dropping the old stuff and refilling it. But instead of removing the thermostat I just ran the lump upto temperature because I didn't have a replacement gasket for the thermostat housing, which last time I had to do up using instant gasket. It worked quite well, although not as well as taking the thermostat out obviously as it restricted the flow, but after a couple of bucket fulls it was running fairly clear. The only thing I am not sure about this method is that the water from the hosepipe is cold and the engine will be hot after a few minutes running which some people might say would do the headgasket in.

It wouldnt really affect it using cold water unless the engine was red hot, just flushing the coolant out is fine
