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

Had to be in a meeting away from my place so used the opportunity to test two CCU board using my NSX.



After getting back to my place, time to vacuum fill the cooling system.

Another opportunity to carry out vacuum leak check and left it like this for more than 40min.

While doing this, re-installed the oil pressure warning switch cable to the oil cooler.


Quite often, this cable was not routed properly and also this grommet could dislocate itself.


This one was the same so had to re-tape it in place with high temperature spec one before pushing it into the small white bracket bolted to the mid cover.


In some cases, part of the cable was trapped under the valve cover causing partial cable damage as well as oil seepage over the long period.



Installed the CCU back in place and started to re-assemble the interior panels.


Kept the centre arm rest off as I need to access the parking brake cable adjuster later during the brake system overhaul.


Before putting back the battery, blew the air into the A/C evaporator to take out as much debris as possible.


Battery installed in preparation for the engine fire up.


I always wear ear plugs before installing the battery because quite often, the security system will make huge noise when first time the battery was connected.


The battery will be removed again as I need to wash the evaporator any way.

The vacuum gauge didn’t move at all so happy with the result and started filling the system.


This is 3.2L engine so it doesn’t take as much coolant as 3.0L one but still, you need just about 16.0L of coolant.


Fired up the engine and kept running it to bring up the temperature to pressurise the system.


Blip the throttle occasionally to move any remaining bubbles in the system back to the header tank.


Let the engine to cool down to adjust the coolant level.


It will be adjusted again after the test driving session but I’ll probably do it after overhauling the brake system.


I can't move the car any way as I need to torque the bolts for the rear anti roll bar under 1G first.


They are still loose as I had to remove the mounting bracket to access one of the fixing bolt at the TB rear mid cover.


It has a bracket for the secondary O2 sensors so I prefer removing the anti roll bar bracket to get access to it on four O2 sensor models.


Ran out of time to carry out the compression check but I’ll do this after cleaning the TH butterfly.


The chemical states that the engine needs to be cold.


Almost done.
