Hey,

Needed to replace my engine fan due to larger radiator.

Went down the thermo-fan path and now need a controller!

I am after a thermo fan controller which reads water temp sensor (better to get another water temp sensor), can define a turn-on temperature (85degrees) and turns off when reaches another temperature (80degrees)

and turns on constantly when AC is on.

What is the best option to do this?

I have found;

http://www.spalusa.com/store/main.aspx?p=i...item=FAN-PWM-V3 but they want $160usd for it O_o

Thanks for the help

Drift have a pretty nice looking fan controller & at a very reasonable price...

Haven't used one myself but have heard good things about them. Check it out on their website.

As for the a/c side of things I think you're on the right track. May need a 5-pin relay with two switch points, one for fan controller, one for a/c...

Cant find an instruction manual for it. The site doesnt say much about its functions which is a pain.

i have a hks fan controller, comes with loom etc, it gives in-car temp reading etc, never used, u just need to download the user manual and ur good to go

exactly like this

Hey,

Thanks for that, let me do some reading up on it to see if it can do what I am after.

Ill try and find a user manual.

Thanks for the links Trent.

Cant find user manual for the Drift controller so unsure how it exactly works. Im leaning towards the Spal thermo controller which can control two fans independently and loads them up gradually from 50% to 100% if temperature increases. Stops two thermos turning on at 100% and draining my car of electricity haha.

Looking into fitting an AU thermo shroud as many have done in the past. If it doesnt fit, ill go down the path of your flex-a-lite low profiles.

Oh how i wish you still did mechanical work ;)

on another note (if you see this reply);

had to replace the gtr injectors 440cc with 550cc due to leaks!. Is there a way I can limp the car down to your place for a tune?

Cheers

sounds like an easy job for a small microcontroller and a relay/thyristor... could even run it on PWM using a thyristor to keep a more constant temp.

haha well you seem to know whats going on. Make one up and earn some quick cash :(

Maybe i should. wonder if anyone else would want one.

The first one would be a very rough prototype, if i was to make one. Not too pretty to look at...

I'll have a look at water temp sensors, do ya know where the stock one is located?

this is where it is for the r32, not sure on any other model skyline

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.

      Just saw this, redacted names. It's on a R33 GTS-t Facebook group. Looks like still teething issues.
