yeah the 2012 nismos come with 88kpa pressure cap which is way less than 2009 and even the upgraded nismo am talking about thats why i changed , so who ever has the old caps is lucky , hmmm not sure about which cap to change ? we changed both and its running fine but why would nissan change the set up ? their has to be a reason for going to a less pressure cap and even change places putting the one that has a pressure relief to the water resevoir place and the one to the hose just has a nissan sign with no pressure relief inside the cap and no pressure reading on top . come on guys jump in and share :driving:

u can see clearly in the link below that in 2012 370z models they changed the cooling system abit to make similar to the gtr which uses 0 pressure cap next to the engine and uses pressurized cap on the reservoir cap , in older models it was the other way around since older models had a plastic cap on the reservoir so in my case i will just reuse the 0 pressure cap next to the engine and leave the upgraded cap on the reservoir since stock suck ,
keeps u thinking why they did that ? hmmmm:stirthepot: 2012 370z nismo engine (0 pressure cap on the engine side) 2012 Nissan 370Z NISMO Coupe Engine Photos | GTcarlot.com 2011 370z nismo (pressurized cap next to the engine side) 2011 Nissan Nismo 370Z: Grassroots Motorsports New Car Reviews gtr engine bay (0 pressure cap on the engine side) 2012 Nissan GTR – New, improved and pricey. | JDM Wallpapers | HQ Japanese Import Wallpapers |

To make the unit a "drop-in fit" we could only make the unit a larger 1 row. Otherwise there would be a good amount of cutting to install a larger unit, and would most likely cut down our potential market base. We've just given a unit to motoIQ.com to do a real-life before/after track test with temperature logging. The results should be published within a month. We were also on Bullet's "White dragon", and dynoed at 990HP. If you have a massive intercooler sucking in hot/warm air - then the warm air, which is now even hotter after going through the intercooler, has to go through the condenser and finally through the radiator (even hotter air) - you will need a radiator with a much larger capacity (at least large 2/3 rows) - there is no space for this in the vehicle without removing the condenser or major structural changes. To top it all off, the exit for air flow after the fans is very limited as well. The temperatures of the middle east are an extreme case of vehicle cooling problems. I personally would not buy a 370Z in the middle east because there is not enough space/flow to fix the factory cooling issues. With that being said, our unit has had great success in many track and normal ambient temp settings.. even with cars with F.I. |

I'm curious, if I can pick your brain for a minute here derailing this thread. I've been thinking down the line about getting rid of my 19-row Setrab oil cooler and going to a Laminova oil:water exchanger instead (this on a car that just does 30-minute HPDEs, in TX heat, and no FI). There's not a lot of data about going this route yet, although I think Travis's first attempt ended up with the Laminova being good enough to cool the oil, but the stock radiator not being able to handle the extra heat in the water system, IIRC. AM Performance successfully ran a similar setup during their brief existence in the Conti series, but not sure what they were using for a radiator. Any guess as to whether yours would handle the heat from this? |
its cool that csf is being on track , but i guess their isnt anything wrong giving an opinion , middleeast or not hot or cold , tests should have been done in climates way hotter than here for example , take vettes for example they have limited airflow , when dewitts made their radiator they made an option for radiator only or radiator plus fans , so u guys could have done that in my opinion than letting the customer go and fine their own fans with spal , but again ur radiators are cool and i used them for 3 z's in the middleeast but they need a helper such as spal fans period to make a Z run at its best , so i hope this thread will be a good pusher for u guys to make a complete kit with fans ect ect and make us worldwide run as cool as a camri :bowrofl:
csf guys do u guys know why nissan changed the radiator setup on the 2012, and made it typical as the r35 ? as mentioned in my above replies ? thanks |
On the change for the radiator setup in 2012, that is when they introduced the water oil cooler.
From what I have seen the oil cooler uses radiator coolant which might explain the redesign. |
makes sense :yum:
i opened a thread regarding the fan control setting by temp and made it to come on fully at 195f , factory settings suck , but the qustion is did anyone change the ac pressure setting ? their are fan setting by temp an speed and their is by ac pressure , most ppl didnt mess with it , but i have a feeling it might help .again u have ac problems , just change your fans and weak them to come on early + distilled water and wetter for better cooling . problem solved :tiphat: i cant believe factory fan cfm's are 500 each !! even a maxima and taurus are way:bowrofl::bowrofl: higher |

woow 116 thats winter loool its 130 today :shakes head:
wish u the best , but i think 185 full power is abit too low since as i read if u have stock thermostat it opens fully at 180-185 so fans should be at full power atleast 195 , 10 degrees after the thermostat . dont count on this info though |
I would not put the fans on before 195, let the themostat open at least first then have them kick on.
If you are still having problems the bigger cfm fans will be very good. That is one thing I wish I had did when we upgraded the radiator but it was a bit of a rush so we just took out the OEM and put in the CSF radiator quickly (and yes it is a very quick job actually). |

SPAL USA
they fit but need some tweakin since they are smaller in size but stronger 3 times , u can get them from other vendors , for cheaper such as motion lab :tiphat: |

i dont think anything will go wrong if u set it up st 185 but it advisable to stay 10 degrees higher than the thermostat opening , thats why i mentioned 195 , i even set mine at 201 , waiting for the tuner to come back to set at 195 , but again doin the fan mod by it self didnt help us regarding the ac getting hot in sotp go traffic just made the coolant stay lower thats all , if u want the ac to work u have to put stronger fans or leave the stock fan and pusher fan behind the intercooler to push air on the radiator/condensor , but we said we dont want more voltage with this extra fan thingy so we installed the spal fan i mentioned , it wasnt easy though an needed little work
it works fine all u need is fan harness kit and a 185 or 195 harness kit as well and brackets or straps . |
