You didn't state it, but I assume that you have
PROPERLY bleed all of the air out of the system, the
easy way to do it is to (engine cold) fill the
reservoir to the top and the overflow tank to the max
line.  Take the grill off, drive around till the
engine is good and warm -  shall we say hot - then:
1) open  the bleeder value on the thermostat, should
be coolant coming out not air, close this valve  2)
unscrew the nut on the left side of the top of the
radiator (up front).  Only unscrew this nut (13 mm)
about one or one and half turns.  I'll bet that you
hear a lot of hissing as the pressurized coolant
system forces the air out.  When air stops and coolant
starts dribbling out, screw in the  nut again - good
and snug but not gorilla tight.

As the engine cools down, the reservoir cap will open
and draw coolant in from the overflow tank.

Works for me.  M
