Vacuum filled the Honda Type-2 blue coolant.
Nothing special here and probably you've got bored by
looking at the same photos many times in my blog.
Bear with me as it's for each owner and the photos are stored in
their individual album.




The new CL master cyl.
I was quite surprised to see the small seepage on the existing one
at such low mileage but the amount of dark green/black residue from
the inner rubber seal and the piston cyl wall was enormous so
somewhat understandable.




Probably RHD car is easier than the LHD one when installing the new
CL master cyl as long as you don’t have so many extra wires, parts, etc.
So many obstacles under the bonnet on this NSX......


As a side note, if you struggle to align the two stud bolts into the
CL pedal bracket inside the cabin, then just loosen the 10mm bolt
at the top of the bracket slightly. Don't loosen too much and just
enough so that you can align the bolt hole on the bracket while
pulling the master cyl body from the cabin side.




Also, once you have bled the CL Hyd sys, please double check the
amount of free play for both the pedal and the CL master cyl pushrod.
I took this video for another owner the other day and it's using my NSX
with Type-R CL pedal + damperless joint so not necessarily the same
amount of free play but you will get the idea.






The dark green/black debris were washed out and
the reservoir cleaned to this level.




Battery, etc back in place and ready for the fire up.


Before the fire up, carried out short burst of cranking many times
while disabling the IG and INJ.
1st stage quick bleeding of the cooling system carried out.




Quick 30 - 60sec fire up in order to push remaining air pockets out
to the heater core at the front as well as to the header tank at
the engine bay.

Time to carry out the thorough bleeding of the cooling system.




And ready to fire up and warm up the engine to the operating temperature.

Very smooth idle and nice sound although that right side head light
height adjuster was making random noise in the background.
I couldn't hear it while the air pump was operating and
the engine was in fast idle mode that the aftermarket exh was too loud.

As the battery was disconnected, the ECU lost all of the stored
coefficient value and as reported at the very beginning of the service,
there was still small misfire/hesitation like symptom (although no CEL)
on fast idle/warm up stage but then it disappeared once the engine has
warmed up.
The owner has six new 3pin spare IG coils and although I don’t have the
new PFR6L-11 spec spark plugs, I have good used 6G ones that can be
used for quick check as well.
Hope it’s not EGR related and just needs re-learning of ECU.
Will connect the OBD2 scanner with my mobile phone to see the
fuel trimmer % and check the base idle rpm later as I washed the
TH body thoroughly and the idle adjust screw was never touched in the past.




I really need to bleed the CL Hyd sys and the Brake system now as I can’t
even go through the gears on the lift before going out for the
test driving session.

My boss is flying out to Japan very soon and with many other projects
getting busy, bit overloaded but hope to return this NSX to the owner soon.

I’m getting old.......
My back hurts after replacing the CL master cyl......
I already injured my back in the past and couldn't move so need to
be very careful not repeating it....
