Subject:      Cleaning cooling system with engine out.
Content-Type: text/plain; charset=us-ascii; format=flowed

Hi all,

Does anyone have a recommendation for how to clean out the
cooling system on an '84 Westy while the engine is out being
rebuilt?  This engine failed by breaking a head stud and there
was coolent leakage into the oil as well as oil leakage into
the coolent.

I am rebuilding the engine and I will remove the radiator and
take it to the shop for cleaning/testing but I not sure how to
get the oil/water/emulsion out of the hoses and pipes under
the vehicle.

When I took 'auto mechanics' in high school we had a device called
a "Zoo Flush Gun" which was a nozzle device to which was attached
a water source as well as a compressed air source.  The output was
a high velocity, high volume water froth.  This would probably be
great for this application, assuming that I disconnect the radiator
and heater cores and flush them seperately.  But I don't know where
to find such a device.

Thanks,
