hey guys, i can't believe i've had my car for almost a year now and i only JUST noticed that i have a little green plug up front that's unplugged!!

Everything in the car works ok, except for my boost gauge...but i'm confused as to wtf that little green thing is supposed to do?! is it simply the connector to make the boost gauge work? i didn't just want to plug it back in without knowing what it's supposed to do first...

well that's what i thought too but the temp gauge is working..

in my car, thats a sensor to switch the thermo fan to the higher speed

but you have a clutch fan, so im not really sure

someone with an r33 should be able to help you

I'm pretty sure that plug connects the thermo fan on the front of the radiator, which only comes on when coolant/engine hits a certain temp - nothing to do with the boost gauge I'm afraid.

Perhaps check to see if the MAP sensor for the boost gauge is also disconnected (little black box tucked away down the back of the engine bay in the driver-side corner)...should have an electrical connector and a vacuum hose connected.

It plugs into the other green plug, on the radiator!!!! That leads down to the thermo switch in the bottom tank that tells the A/C thermo fan (the one out front of the radiator) to switch on when the coolant starts to get a buit too hot.

Thats the connector for the thermo switch that turns the sub cooling fan on. Its an extra fan incase the engine is idling and the clutch fan isnt doing enough revolutions to create sufficient airflow to cool the engine coolant. I think it also comes on when you switch your AC on, but my AC has never worked so i cant back that up. But it would make sense as there is no way of electronically switching on a heat activated clutch fan!

Thermo fan man. That's where mine goes, and I have to unplug it to take the radiator out. If you've had the timing belt changed or something like that recently, then someone left it unplugged.

Does the A/C condenser core have a seperate fan to the one we're talking about???

man what's going on... in that pic you sent there's clearly another plug that it goes into... did you not see it??

lol, true true, we all saw it, but no one stated the obvious.

just plug it in, it's even colour coded. then whatever it does, it'll do it. done

i think you're right on the money, i had the timing belt and water pump replaced a few months ago and they probably forgot to plug it back in..

and yes i was going to plug it back in but i just wasn't sure what it would've really done

thanks for the feed back guys!

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
