guys just quickly, iv got an R33 S1 GTST, now the stock thermal fan at the front, wen does it kick in or does it. Iv heard it supposed to kick in wen the A/C is turned on, but it is NOT activated by temperature levels. Mine doesn't activate wen i turn the a/c on at all, does this mean its not working???

let me know ur thoughts

cheers

it will only switch on when your a/c is on and you go ever a certain engine temp. the temp probe is the one screwed into the bottom of your radiator. you could check to see if the probe is plugged in. alternatively if you have or know anyone that has a consult cable and software you can do an active test where you switch it on through that.

yeah i believe it will come on with aircon when required.

on a side note, what happens when you put a fmic in front of that temp probe?

does it see temps as hotter and therefore turn on more readily? any adverse affects?

nah that a different probe. the one your taking about is the outside air temp. there is one screwed into the bottom of the radiator, so that when the coolant/engine temp gets to hot it switches on. the only time i've ever heard the fan come on was in the middle of summer and in really heavy city traffic.

so that thermo fan actually kicks in to control engine temps???

i thought it was purely for the aircon

thanks fellas.

to comment i would've assumed it should kick in at high engine temps like other cars.

but like mentioned above i was told purely for aircon. so even if the aircon is on it wont kick in until a certain temp??

these cars must hav good cooling...!!

I will be converting to a 16" thermo fan as part of my RB30DET conversion. Fan will be spaced approx 30-40mm off the radiator and use the stock shroud. Fan opperation will be speed controlled using a picaxe micro controller and stand-alone temperature probe.

The whole process has been halted at the moment due to the x-mas break though...

you'd be better off using AU falcon thermo's and shroud and simply attach to your radiator and seal the edges.

      A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.

      Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?

      Excuse me for butting in....but which part of ADHD can be considered a superpower? I would have though it far more likely that some ASD comorbidity is more likely to be contributing to an ability to hyperfocus on something. ADHD being aimed somewhat in the other direction. My shed looks like your shed. My whiteboard list of unfinished projects has entries going back 15 years. I know what you're talking about - I just struggle to connect ADHD to the results being discussed.

      Thanks for reaching out!  It's a blessing and a curse at the same time.  I'm undiagnosed but it doesn't take a rocket scientist to see it in me... I have more half started projects laying around my house, shed, garden, etc taking up space and money, destroying aesthetics than if I added up all of my mates projects together. But, ADHD gives me the ability to hyper focus on things that no mere mortal could even  comprehend.  A recent pool build is an example of that....  I dont know anyone else that would be dumb enough and focused enough to take on then complete something of that magnitude. I call ADHD a superpower but it can equally be completely destructive if not controlled and focusedon the right places. Addiction is a major concern to ADHD people and thankfully my addictions have been no worse than projects, XBOX, chocolate and being an arsehole! It's often hereditary and my 13 year old son is currently learning how to drive it at the moment. Keep lurking! If i can finally finish this bloody thing at some point it will be a win for all of us ADHD'ers! 🤪
