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

Vacuum leak check on the cooling system.

Left it nearly 1Hr as I have never worked on this NSX.





While waiting, quick oil change with fresh oil in the new oil filter.
Extracted extra used oil from the top.





Started re-connecting the battery. By now, it's fully conditioned by the battery conditioner.
As always, never tighten it to the end. Just stop once you started feeling enough resistance at the nut.
You should see some gap at the end of the terminal. Otherwise, you have overtightened it or the terminal itself was already damaged in the past.




Vacuum fill the blue Honda Type 2 coolant.



Disable the INJ and short burst of cranking followed by longer cranking to build up the oil pressure and splash it sround the engine.






After the initial bleeding, quick 30sec fire up to push the remaining air pocket and another bleeding.
Happy with it so proper fire up and bring the engine to the operating temperature until the rad fan kicks in.
As the weather got much colder recently, it took about 30min for the rad fan to start spinning.


Left the engine to cool down overnight and adjusted the coolant level.


Hope to run the car today and tomorrow in order to apply some heat and vibration into the drive shaft spline although the weather forecast is not great at all for tomorrow so may need to re-think about the plan.


More to folllow later.
