        Sorry folks but I just have  to chime in on this highly incorrect
statement.  I bleed these waterboxer  systems here on a daily basis and no
jacking or incline is necessary.  USE  the force of the waterpump !  It's so
easy it's makes my head spin to read  all these convoluted ways to get the
air out.  First and foremost  the 2.1 systems are self bleeding, that's the
reason for that coolant tube  going around the perimeter of the engine bay.
It siphons off air, sends it  over to the expansion tank, then when the
system exceeds the 13 lbs that cap is  set for, the air is released to the
overflow tank and it goes out to the  atmosphere where it belongs !  Now how to
bleed the waterboxer systems both  1.9 and 2.1.  Here we go again and I say
again as I'm sure I wrote this  before.  Open the two bleeders on the top of
the radiator and on the top of  the thermostat housing, fill the system
through the expansion tank, start the  engine and let idle, fill the system as
much as you can at idle, fill the  overflow tank to the MAX mark, set the
engine to run at 2000 ~ 3000 rpm,  continue filling the system until full, check
the bleeder at the radiator to see  when only fluid is coming out, close
this bleeder, fill the expansion tank and  replace the cap, lower the rpm to
idle, check that no fluid is coming out of the  expansion cap nipple, if so
the cap is defective and should be replaced now, if  good connect the hose to
the overflow tank, let run for 15 to 30 minutes at idle  to check that the
rad fan is cycling off and on, shut down, close the bleeder on  the
thermostat housing, let cool overnight, any air left in the system will now  have
been transferred to the overflow tank and you can refill it to it MAX  level,
job completed.

>>>>The only way to really bleed the WBX is to either  raise the front end
with a floor jack (pretty high in the air - be careful)  or to park on
a steep hill and bleed it while on the incline.  The  front end needs
to be higher than one would think in order to get all the  air removed.
And then bleed it over several days because some trapped air  will
eventually move forward.  Of course, the engine needs to be warm  and
idling at the  time.<<<<<<<
