hey guys, I just had my CSF Radiator and Z1 Oil cooler kit installed on my car and drove it home and parked it. When I got out and walked over to the passenger side after letting it sit for a few minutes, I noticed some water leaking from underneath my car. I think that it is the AC leaking. Is it normal for that to happen after the AC gets recharged?

Are you sure it's not normal condensation from the ac?

This. :iagree:

It is normal for the A/C to drain condensation.

This discussion is prompt at the right time, summer is starting to boil and consider a radiator would be up on my list.
question for the Turbo and SS guys, is there enough space to install big oil cooler, csf radiator and intercooler?

Yes and no.
TT Intercooler->Oil Cooler (up to a certain size)->Radiator will work, but for the single SC guys (GTM) the space between the intercooler & radiator is to small so the oil cooler is mounted off to one side.

Yes there will be space... theoretically. With my build, my oil coolers have to go in front of the intercoolers. If I had an aftermarket front bumper with a larger opening, then things could be shuffled a bit to make it more effective. FYI, my car has the twin IC setup the MHI has and the crash bumper is in place. I opted for the larger and more powerful SPAL fans to help compensate the airflow deficiency. I'll see how it works when I get the car back home.

I stared a thread a few weeks back regarding my Mishimoto Radiator install. Thread link and post below.

Overall I feel the NEW Mishimoto Radiator for our Z is top quality and performs outstanding. The deciding factor for me was that it has 2 rows and being 40mm thick allows for more coolant.

____________________________________

I installed the NEW Mishimoto Radiator over the weekend. The install was straight-forward and an easy install for you Do-It-Yourselfers. I was very impressed with the quality and that everything fit perfectly without having to modify anything on my Z.

The stock radiator core is only 13mm thick with 1 row. The Mishimoto radiator core is a massive 40mm thick with 2 rows. I don’t have any gauges to compare the temperature differences, however, I use my infrared temperature gun to gather a few reading. I saw an average of 20-30 degree decrease in temperature when comparing different areas of the radiator and engine before and after install. Also my oil temps are much lower as well. This was an unforeseen benefit and much needed living in Florida.

I posted a YouTube video and some pics below. You may find them useful if you are looking to replace your stock radiator.

Feel free to contact me if you have any questions.

I think Mishimotos' won't fit with an intercooler + oilcooler

The turbo intercoolers bolt to the location where the front crash bar usually is. There's tons of room between the intercooler and radiator. The sc guys don't have much room.

Hey guys,

We have tested our aluminum radiator with our direct fit oil cooler and fitment is perfect with no modification necessary. Our aluminum radiator is significantly thicker than the stock unit which may bring about questions regarding intercooler fitment. I spoke with our engineers and the Mishimoto radiator is expanded both frontward and backward in the car. This radiator adds 20mm to the front face of the radiator towards the front bumper. This means from the front of our radiator/AC condenser assembly to the end of the lower radiator support is around 50mm. This leaves around 4 inches of space between the A/C condenser and the back side of the bumper support beam.

If you are utilizing a front mount intercooler that is mounted in front of the crash beam then fitment should not be a problem at all. We have not tested fitment with an intercooler behind the crash beam so we are unable to confirm fitment. This really depends on the thickness of the cooler. If you would like to send me the specs of your intercooler I would be happy to compare this to our drawings and see if we can come to a conclusion. Being able to fit all Mishimoto cooling components and an intercooler really depends on the intercooler size and its mounting points. I would be happy to help with any specific questions, feel free to shoot me a PM. :tup:

Thanks!

It will fit I know someone with one on a Turbo Z

I am switching out my CSF Radiator for the Mishimoto one in the next few weeks and will post results.

A rad might be on my winter project list... I'm looking to beef things up for some track days next summer. Looking forward to your results.

I have a question. Can you tell me the specs on the power steering cooler? Looks like a direct bolt on replacement but a lot longer.

Remember guys, not all radiators are created equal.

Here is a comparison photograph taken this past week comparing CSF's industry leading "B-Tube" technology versus the "M" company's tubes.

It is apparent from the comaprison photo that our tubes:
1) Have a much better flow rate.
2) Our tubes have more surface area contact with the coolant allowing for better heat transfer efficiency (~15% more contact)
3) Because of the B-tube structure, we can use thinner aluminum but still have a stronger tube which has two advantages:
A) Ensures that non of our tubes are squished when the tubes are inserted into the headerplate during the manufacturing process. Sqished tubes significantly reduce the effectiveness of a radiator.
B) Allows for even better heat transfer efficiency because of the thinner aluminum.

"B-tube" technology is the world's best radiator tube only available in the performance aftermarket by CSF, a true radiator manufacture with over 65 years of experience and OE clients across the world.

My Recent Mishimoto Experience
 

To Mishimoto from CSF? Never heard that one before. I just replaced my Mishimoto thermostat(left) with 4k miles on it for my stock unit(right) with 6k on it after hearing too many horror stories about their craftsmanship, leaky radiators and failed thermostats. As you can see the seal is already busted on the Mishimoto thermostat. I had a friend who had a Mishimoto thermostat fail on his Subaru which resulted in a ruined bottom end. From what I understand they make a decent oil cooler!

I do have the CSF radiator though, so I guess I can be labeled as biased.

Picture's look good but what matter is real world results. I have had the CSF radiator for some time and i can tell you right now it does not like to get pushed in heat . I have also seen both right next to each other ,and the Mishimoto is larger has 2 row for extra not one like the CSF. Now this does not make it better I will post the results like I have stated once I make the switch.

Make me a radiator that can handle at least 17-PSI of boost for one pull up to 150 mph hit 220+ coolant temp and not take forever to come down. I have gotten the CSF hot very easy and not even on my highest boost setting.

I would like to know as well, please keep us informed :)

The ps cooler looks to me from a gtr

thanks.



Question to CSF or Mishimoto. How does your 7AT cooling done through the radiator compare to the stock radiator and which is better?

G37 also has the longer oem ps cooler.

G37 power steering cooler

From what I understand, CSF is the only manufacture to produce a unit for the automatic transmission (CSF #7011). We use the same water-to-oil 7-plate transmission oil cooler as the original unit. This is the largest size we could fit into the unit.

nice, I didn't know the g37 had a bigger PS! good to know

Doesn't the GTM radiator support the 7at also?

Yes. But I would put that at a different price and performance bracket. You'll be spending $1400-$1700 for theirs because it requires a new fan shroud. It's overkill for most Z's.

Our target market for this radiator was the manual transmission Z, with optimum performance in mind for these specific cars. Our radiator can be adapted to work with the automatic transmission, with the addition of our external transmission cooler.

I will wait for automatic version .

... Heat exchanger is a little useless IMO, regular oil cooler would be much more efficient...
... CSF offers a 7AT version with a trans cooler too...
... CSF's condenser is removable too...

Yes, I'm biased now to CSF:
http://www.the370z.com/nissan-370z-g...r-service.html

proper shrouding for alot of the guys posting here would help huge. No one has even mentioned anything about that

Made my choice easy...Thanks for the great review and story of customer service Depointfive!!:ugh2:

Most are focused on a drop in solution, taking advantage of existing OEM parts.
Also, still waiting on results from another forum member if the GTM SPAL fan upgrade is plug-n-play with the CSF radiator. Instead of having to buy the fans, re-wire your fan controls, build new mounting solutions, etc.

I don't understand. If you're NA and worried about water temp. Why not get a Thermostat?

Because the ones for our car suck, one throws a CEL code, another is some cheap china made POS, and so far no one has made a decent upgrade.
Also, a radiator is a better solution, as while on the track it will help keep you much cooler versus the OEM radiator.

Because the only lower temp aftermarket thermostat is Mishimoto, and they make cheap Chinese garbage that fail all of the time. If your thermostat fails closed, you're boned.

I wasn't aware they were that bad. I guess I found it hard to believe it was difficult to mess up such a simple part. I know some racing teams run them, however, I'm sure they rebuild those motors all the time anyway and longevity of a $65 part is probably the least of their problems.

thanks for the insight.

I would imagine many of the racing teams have custom radiators with completely different thermostats than ours to optimize their track performance and reliability.

Anything Mishimoto has a high likelihood of giving you an issue. I used one of their radiators, and it fit terribly and the welds were horrendous. At least it held water. They'll come on here and say that their stuff is great and post a slick video, but you're rolling the dice. Besides outsourcing their production to [REDACTED], their quality control is godawful. Some people will get an acceptable part. Others (like one member here) have their thermostat fail in 6k miles.

Both manufacturers products are made in China, but who you chose as the production partner means a lot I suppose.

I ended up installing the Mishimoto a month or so ago and track tested it, so far so good. The welds were clean, perhaps not the prettiest but then aluminum is difficult to weld. Water temperatures on track were lower and it held up under pressure which is all I cared about.

If I wanted the best I would go with PWR/Nismo (Australia) or GTM (outsourced to US producer), but these options are at least double the price and a lot harder to install, so maybe down the road if budget allows. Doran uses the PWR/Nismo unit.

Our radiators are not manufactured in China, and we do not have an external production partner. We own and operate our own facotories. All of the R&D is done in-house, and we also have many OE clients around the world...

Just wanted to clear-up any misunderstandings people have about CSF. :tiphat:

Oh yeah, to contribute, i have a CSF rad, and the Nismo 34 row oil cooler with custom shrouding.
