The parts fit perfectly. You will need to use a little grey silicone RTV to keep the gasket in place while re-assembling.

*update* while working on something else, I found that the bottom plug that goes to the Drivers side fan was loose. Left fan was not working. Please ensure you use extra force to push the plug in. Once secure, it will be hard to pull out.

Not taking the risk I have ordered from Nissan CBR. They are shipping the part from Nissan VIC. Items ordered for a total cost of $110.95 : 21200-JK20A -Thermostat 1305031U00 - Gasket Will keep you posted on the fitment.

Hey folks, I'm trying to get a replacement for my thermostat. It's does not seem to open consistently. Sometimes temp raises above normal before opening, radiator resovoir fills. I know our part number is 21200-JK20A. There are a couple of Mishimoto ones that are not exact fit. This one's enclosure is too thin. (SKU: MMTS-350Z-07), This one runs too cold and in winter engine constantly tries to warm up. (MMTS-370Z-10L) Good read : https://g35driver.com/forums/g35-sedan-v36-2007-08/468030-v36-vq35hr-thermostat-install-warning.html I'll ring the stealership tomorrow to see if they might have the part. Does anyone have any leads on procuring a thermostat? Thanks! Elcid

I've got this and works well. Had it it since May'23. Very bright. Philips 85V 35W Xenon WhiteVision Gen 2 D2S Car Headlight Bulb https://amzn.asia/d/gbHSMbU

Ah nice one! Interesting your clip broke, maybe quality of the plastic might be inconsistent...

Fan turns on perfect! So all good

Hey Awsam, The replacement worked perfect. Exact hardware match and works well now. No constantly ON fans. Checked when the engine was cold, with (both fans on) and without A/C (fans off) - works well. Will be confirming that the fans turn on when the engine gets hot too. Should be fine, will report back if not. Use this vid for detail of removal process : Images of the part attached. The unmarked one is the new one. I bought this : https://www.ebay.com.au/itm/144660931416?mkcid=16&mkevt=1&mkrid=705-154756-20017-0&ssspo=ywpbmkztsqc&sssrc=2349624&ssuid=JqKD_6noRQW&var=&widget_ver=artemis&media=COPY Happy DIY-ing!

Great idea on the PTFE lubricant too. Agree, avoid WD -40 since it will get worse over time..

Lol, will keep you posted mate. If I recall right the squeaks can be solved the using a long straw nozzled spray grease , spraying straight into the fan motor.

Some info to share after a bit of research: The updated Nissan OEM part number for my 2007, V36 350GT is : 214934GA0A (old part number is 21493EH10A) - Circa $100 to $200 AUD dependant on brand/quality The interchangeable part is (as seen here: https://www.aliexpress.com/item/1005004459559212.html) : 1355A408 (Cooling Fan Control Module For Mitsubishi Lancer 02-06 ) - Circa $30-40 (AUssie stock and free delivery) example : https://www.ebay.com.au/itm/153550014872 Both these parts look identical, however I'll be purchasing the MIsubishi part number. The OEMs supplier is the same for Nissan/Infiniti/Mitsubishi - Calsonic Kansei part# 21493 FYI My fan controller needs changing as the fan is always on. Happy DIY-ing folks!

Interesting that the Plenum bolts solved his issue : https://g35driver.com/forums/engine-drivetrain-forced-induction/340934-hesitation-bucking.html Thought it might be of interest in case some have not solved the issue. FYI - My (newer, second) 2007 G35 does not have this issue.

Also by the way of an update, she's followed me to ACT! Been 2 years now!

Hey mate, have you heard back? This just cemented my decision - Sticking to OEM. Was thinking of making a minor upgrade to these slotted ones...but won't now.
