Draining Coolant

[Curt Sprenger]

When draining the coolant by opening the radiator bottom tank drain
valve, I expected to see the coolant flow become less because the
radiator cap was not removed. The coolant flow continued at the same
flow until all the coolant was drained. Any thoughts on this? Perhaps a
bad radiator cap letting in air?

You may have only drained part of the system Curt? Be sure the front
heater lines & the aftercooler are flushed out too, I hook up a hose to
mine, flush it & then hook up the air compressor & blow it all out with
air before refilling. I would go ahead & replace the rad cap as a matter
of prevention. I pull the covers off the thermostats too & check (or
replace) them.

I'm replacing all of the hoses, coolant, fuel, oil.
