Stupid me forgot to check the orientation of the airflow. Luckily it was just help on by a team zip tie

Fan and radiator installed and operating correctly.

No I need to figure out these left over hoses and see how the clutch works.

Quick update. Took it for an hour drive in highway and dead stop traffic. Temps stayed very low. Cant hear noticeable volume change in the cabin. Easy job this one. If you have a hydraulic fan on your JDM Celsior and are about to replace any of the assembly, consider this swap.

So I removed the water pump today and while doing so removed what would be the fan clutch assembly for you guys with non jdm cars.

The clutch assembly on this is quite complicated and made removal for a timing belt job a little different to the ls400

I'll take photos in the morning g for those interested in the difference.

So this is the fan mount as you would have on your ls400 versions. It was pretty complex. So I just removed the clutch plate and pump.
