Hey guys i was at the driving sports event having a go a drifting last night and all went well but i now have 2 problems.

its an R33 RB25det

I fitted a 52mm alloy radiator and wasnt having an issue with cooling then i noticed it to get a little higher on the temp gauge then the previous runs so i did some grip laps and went in when i got back the front thermo has picked up somthing and jamed it and its stuffed.

same time my fuel guage rose and started to read full.... and pretty sure it dosent make its own fuel so i think somthing is broking or stuck

question

1. i bought a new thermo fan as i dont have a clutch fan (had a crack) 16" davies craig can i use the temp switch that the front thermo ran off or should i put a different one in? and run both off that?

2. what do i look for with the fuel gauge so it reads properly agian?

Thanks guys :)

correct me if im wrong, but the front thermo is almost a meltdown mode fan, kicks in at approx 103 degrees, ive never heard mine going in the 5 years ive had my 32.

many think its an a/c condensor which it isnt either.

maybe go back to clutch fan, no thermo can flow as much as that thing. :)

Thermostat = swap to nismo or other recomended brand, but also run a larger diamater water pump pully to reduce air crevation.

i was thinking of going back to a clutch fan but they are hard to get in good nick and nissan want a million dollars for one, and i dont know if it will fit with the new radiator :(

Will the Nismo thermostat make a difference? i didnt replace it (just did timing belt and water pump)

If i use the 16" thermo fan what temp do you guys think the switch should be? what is the normal operating temp?

Ryan, I have a similar thing with the fuel gauge in my 32. Absolutely NFI what is causing it, but I know it eventually goes back to reading correctly (then "making fuel" again). I say just put up with it.

leave the thermostat as is

long story, but sometimes fitting a higher temp thermostat can help an overheating engine :( seriously

pretty sure u can fit a VL viscous coupling and fan without any issues(burson), yes Nissan viscous coupling was outrageously expensive when i inquired.

Fuel gauge issue is new to me, sounds like a sender unit problem i guess, pull it out of the tank and try moving it by hand, see what it does then.

If it is just the fan that has cracked get a replacement and bolt it on the the fan coupling. Not that expensive. The clutch fan gives you the best cooling of the lot and is much more efficient than the thermo fans. To get good thermo fans that move as much air as the clutch fan will cost you a lot more.

I got a replacement from RHD japan. Nissan should be able to get the same thing out here.

OEM cooling fan

If the coupling is stuffed you can get that from them too

OEM fan coupling

so dont worry about fitting a nismo thermostat? not worth the money?

i'll see it there is enough room with the new radiator if there isnt do you think that the 16" davies will be enough? and what temp should i cut it in at?

Yeah the fuel guage just went up after a lap i spun out on, what dose the sender look like i havnt seen one before but i have changed the fuel pump so i know what to do as far as that, i hope it dosent stay like that forever!

    • Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R. 
    • Thanks. We getting some parts along too so he will be solving the speed issue like next week so i will let you know what he came up with.   
    • 21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.
    • Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.
    • Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
