Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

New GND cable installed.



As mentioned many times, please do not over tighten the terminal cramp.
You should see several mm gap when the cramp is secured to the battery post.
People tends to just tighten it until it hits the end stop.
The cramp is harder material than the battery post so it's just chewing into the
post resulting in loose feeling. Please stop tightening once you start feeling some
resistance.







All coolant hoses are now replaced.
Old ones were the original ones that as soon as I started removing them,
they just cracked.

Scary.....

It all depends on the driving/environment conditions but after about 10 years,
you better start planning about replacing all coolant hoses.
It’s time consuming task (about 8hrs) and the total number of hose depends on
the spec of your NSX but it will be more than 20 for any NSX.




After carrying out the vacuum leak check for about 40min,
happy with the result so the blue Honda Type 2 coolant
went into the system.




While waiting for the result of vacuum leak check on the cooling system,
quickly pressure bled the CL Hyd Sys.

Unlike the brake master cyl, the CL one is just a single piston system so
if you prime it first with your finger, it’s not that difficult to get rid of the
air from the system.




After pressurising the fuel system several times for leak check,
multiple short burst of cranking were carried out.
Everything looked/sounded fine so quick 30sec fire up to push out
any remaining bubbles in the cooling system.
Checked the bleeder plugs and now it’s time for the proper fire up.



Went though each gears including the reverse and after a while,
the engine was nearly at the operating temperature but the engine was
nowhere near to the idle rpm.
