Draining Coolant

[Terry Neal]

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.
