If you mean this button, then it is for the headlight washer: This is the full ECCS (engine management ECU) circuit diagram which shows the original electric radiator fan motor and relays (the fan is two speed). This fan is controlled by the ECCS measuring vehicle speed, engine temperature and A/C on/off state. http://www.ttxtz.com/images/ECCS_colored_m.gif You can see in your photo that the red wire spliced into the green wire on the fan plug is taking the ECCS signal switching on the fan to some other circuit (the relay in your first picture).

Liquid gasket sealer is specified (KP610-00250 or equivalent) for the aluminium inlet and outlet pipe connections. Threadlock on the socket caps not required - see below from FSM (also shows correct torque settings for the bolts). Part#'s and pictures for the items affected (from a US dealer): https://conceptzperformance.com/nissan-infiniti-nissan-oem-300zx-coolant-bypass-tube-90-96-z32-14053-f651a_p_1914.php https://conceptzperformance.com/nissan-infiniti-nissan-oem-300zx-water-pipe-coolant-outlet-bolt-90-96-300zx-z32-16163-f6510_p_4990.php https://conceptzperformance.com/nissan-infiniti-nissan-oem-coolant-bypass-hose-nissan-300zx-z32-14055-f6511_p_1000.php

To get started, LH is nearside/passenger side. You can see L and R markings stamped on the chassis crossmember near the radiator end tanks. The fog light relay (for UK spec rear fogs) is present: Did the car have aftermarket HID's fitted?

Would be fun to have this in a EVZ32!

It's in Japanese. Was this product sold outside the Japanese domestic market?

Here is the Japanese version: https://www.blitz.co.jp/support/manual/electonic/fatt.pdf

Made by Craftsman (see my earlier post #24 on alternatives) marked #8. The bolt head diameter is 13mm. The tool is case hardened and cuts into the bolt head and grips it as you turn it counterclockwise. Just use a ratchet handle and push the tool firmly onto the head of the bolt and turn.

The offending bolt and the tool that removed it.

This type of tool should do the job: https://www.300zx.co.uk/forums/showthread.php?32269 The craftsman set referred to is no longer available: https://www.craftsman.com/products/craftsman-10-pc-damaged-bolt-nut-remover-set-low-profile-bolt-out However, there are equivalents: https://www.screwfix.com/p/erbauer-bolt-nut-remover-set-6-pieces/6083d https://www.toolstation.com/shop/p63045

Snap!

How much material are you having removed - you are aware of the limit?

A number of you have asked for a photo showing the result of using Frost's Ali Clean - Aluminium Castings Cleaner. The product is great at cleaning aluminium castings such as plenums and I've used it on a number of occasions with excellent results. https://www.frost.co.uk/frost-ali-clean-alloy-aluminium-castings-cleaner.html [ATTACH=CONFIG]112929[/ATTACH]

Lubricating oil on the metal pivots will fix that.
