Solved~

Yesterday hooked up to Formula D, this time Han and Ken(mechanic)suggest me do a complete radiator check by pull out the whole radiator and flushed, realignment the radiator fin as well as leaking check, thermostat check and fan check. It take about 3 to 4 hours to finish. I have been told, my fan clutch, thermostat is still in good condition and there is no leaking at all. The possible to cause this happen mainly from:

- Radiator fin, some of it was bend and this retard the air flow into and cause water temperature increase during idling. Since realignment fin was did, the problem should be solved now.

- Thicker aftermarket radiator featuring with stock radiator fan. My car is came with aftermarket radiator and it is thicker than the stock one. Hence, a stock fan size is insufficient to suck in high volume of fresh air through the radiator unless you using a bigger size radiator fan. Anyway, this only have small effect to water temperature since my radiator only slightly thicker than the stock one.

- Fan shroud. My car is came without fan shroud, thus it can't make the air 100% pass through the radiator. But problem is where available a Skyline fan shroud?? However, I skip this 1st and let see how my car running after did the radiator realignment.

One more CBA-R35 transmission gear box problem occur....

Besides tranny gear box, they inspect the rotor as well~

Blue Hippo was being lift up to drain out the water from radiator.

Radiator has been pull out to flush.

Flushed by Ken.

Small part of the radiator fin is bend, thus realignment is required.

While Ken flushing radiator; Han was checking on the fan clutch.

After everything was completed, I drove and while on the way back I noticed my temperature is much lower, when cruising(120 km/h) it only 75C(daytime)and below 70 at night(MFD can't detect it), stop at traffic is 85-90C and idle max is 96C. Since now the problem is solved and I'll concentrate to my next major service. Once again, I'm glad to appreciate to all GTR senior and friends who enlighten me during the time when I feel desperation. Thank you~
