Mishimoto Fan Shroud Kit(review)

[DrtyRat]

I decided to get this after I realized how crappy my altima fans looked w/my new radiator. I purchased this and my radiator from Works Concepts, and one thing I can say for sure, he has the best prices period, and had great communication w/any questions and/or concerns that I had.
I was unable to find any reviews, for 240's, anywhere, so I decided to give one myself.

I couldn't find any reviews or "good" pics so I took some of my own...

I haven't gotten to actually hooking them up since I'm in the middle of redoing my entire cooling system. I do have a couple of issues w/this product.
1. On the 3rd pic you can see a slight gap between the shroud and the fan. Both fans, on both sides, have that slight gap, so I worry about it losing some of its cooling capabilities.
2. When I had my Altima fans, I used weather stripping to create a good seal between the shroud and the radiator, but I was hoping not to have to use it w/this shroud. I see the smallests of gaps around the shroud, and while it may not be anything to worry about, I wonder if I should use the weather stripping again.

I'll update this thread when I finish up my install.

[Bigsyke]

shouldnt make a difference at all in gap per say;

Most computer CPU heatsink/fan combo actually spaces the fan away from the heatsink so the airflow isnt as directional.

I have a good 1" gap and have 0 issues with cooling, id have more of a concern in blocking off the left and right of the radiator so air cant get past it.

What would be even better if the fan shroud spaced the fans back about 6", but still had 0 gap on the fan/radiator, this way the fans motor doesnt have an effect on cooling surface area.

[DrtyRat]

I've got everything installed and running, and I have to admit, this thing is a beast. No weather striping was needed and it cools just as effectively as my altima fans(which is really saying something). I took the car out today, and w/the new rad./fan/thermostat setup, my engine stayed at a rock solid 195. I love the clean look, and the fact that it actually does what it is supposed to is a big plus! I've got a couple of other reviews coming up:

If you guys have any question about any of these product feel free to post them up. I am the proverbial noob when it comes to this kind of thing, so I really just kinda figure this stuff out as I go. In lehman's terms, I'm like 95% of you guys out there :D


On to bigger and better things in the next 2 wks. Hopefully, I'll get my Sard 550cc's installed, boost controller hooked up and the tune finished on my Haltech!

[mishimoto]

Thanks for posting the review, glad you are enjoying the product line!

[silnismo]

Awesome review!

Keep us updated on the other products.

My review on this...its ok if you DONT HAVE AIR CON.

i bought the kit because 1 of my FAL duals burned out, we wired the one remaining fan to ignition on so its constantly running...

this 1 FAL fan + MY koyo, never overheated in city or highway driving, in fact it stayed at pretty much the normal temp on the guage.

installed the mishimoto fan shroud kit...both wired to ignition on.
They kept the car at the same level as the 1 FAL...

so yesterday i take the car out to go buy a Gracer lip for my jdm kouki bumper, 70 mile journey. Its hot as fuck so i turn on the a/c...after about 5 minutes i look at the temp guage...its double the height it usually sits at. This is going 70mph on the highway.

Shut off the a/c and the needle climbs down to normal temp within 2 minutes.

needless to say im gonna be stuck not using my a/c for a lil while.

i am in the process of looking for an S14 SR stock clutch fan/shroud (or ill buy the shroud brand new)...

its way too fucking hot in florida to not have a/c...

[DrtyRat]

I can vouch for the fact that it's too hot in Florida to not have ac. I need to recharge my ac, and I'll post some feed back regarding that.

[boosteds13]

Driving 70 mph there should be enough airflow through the radiator that the fans don't need to be on at all.

[shinmei-2006]

Driving 70 mph there should be enough airflow through the radiator that the fans don't need to be on at all.

exactly.

but these fans weren't compensating for the a/c being on...

[fromxtor]

Rat do you have the PS line yet, I've been thinking about getting one. But I dont have the little transfer tube that goes from the pump to the OE hose. Do you even need that with the ISIS line, or can I go directly into the pump with those fittings?

[artdrifter]

fabricate a custom aluminum shroud. it looks sick bro

[DrtyRat]

Driving 70 mph there should be enough airflow through the radiator that the fans don't need to be on at all.

For now mine are always on, but I will have them hooked up to my EMS so they only come on at a certain temp.

[WoolyS14DET]

+1 for this setup as i am running their radiator and electric fan (with shroud) and if works great no problems at all. Im using a HKS fan controller to control the fans.

[TurboFC3C]

I will have to chime in on this one.

First off, I'd like to say that Mishimoto makes a fine product. I've owned one of their all aluminum radiators for almost a year and a half with zero issues. That is, until I noticed a pinhole leak in the radiator due to my old electric fans rubbing on one point (my dumbass forgot to use cushions when I was readjusting the fan position one day). For those of you who don't know already, Mishimoto offers a LIFETIME warranty on it's products, even for crash cars. I hit up mishimoto through their website and was pleased to see that one of the reps immediately emailed me back with instructions on how to get mine replaced. So A+ to Mishimoto.

Before I put in the new radiator, I decided to pick up the fan shroud as well. To this day i've had zero issues with cooling as the fans do their job quite well. I use A/C damn near everyday and even at a standstill, my A/C blows cold. For the money, this shroud/fan combo is killer. BTW, I drive my 240 at least 54 miles 5 days a week with no issues.

did you use relays to power the fans? or just hood-ass tapping into existing wiring?

i hope you actually did this right....... unlike 98.5% of the population on here

[TurboFC3C]

btw i used a relay with an in-line fuse

[shinmei-2006]

two 30amp relays, one for each fan.

[theslows13]

awesome :D

im actually quite glad to see proper-ness happening

[Okinawandrifter87]

OP did you ever have problems with running this setup with ac in your car?

[Krimlin]

Thread is from 2009...


Also the OP rarely posts here anymore...

[Okinawandrifter87]

^ i saw when thread was from and its an old bump but searched and didnt really find anyone else write reviews with same setup with ac so thought it would be worth a shot to ask just by chance.

[mattack69]

^ i saw when thread was from and its an old bump but searched and didnt really find anyone else write reviews with same setup with ac so thought it would be worth a shot to ask just by chance.

I quite literally just installed this setup and a DiF controller on my S14. I'll post pictures of the fuse box and everything needed to tap so this puppy works in a few. :naughty:

[Okinawandrifter87]

^ Do you have it installed with ac and the temp stays one temp or does it the temp gauge go up like one of the posts above mentioned? And cool thanks!

[mattack69]

(Disclaimer !!! This setup is working 100% for me so don't get all asshurt if for some reason it doesn't work for you. I've included the controller PDF which has trouble shooting at the very end if you run into problems)

Directions / Diagram so you can follow along, also it explains how to set up different fan configurations:

http://diftech.com/skins/computer_shop/customer/install_manuals/Instructions10090.pdf

Current install set up:

I'm running the Mishimoto radiator and fan combo, DiF controller Version C on a KA.

The kit comes with all the wires and connectors, but to make things easier if you are the suck at soldering like me I picked up some inline wire taps that clamp down on the wire you want to tap.

Ok so first thing is first you have to locate your temp sensor, I have a KA so right above the water pump there is a red plug (temp sensor). Don't go yanking on it there is a staple shaped retaining clip you have to pull down from the bottom of the plug before you can pull the plug.

http://www.frsport.com/writeups/diffc/dif-11-slicing-done.jpg

Once you have that guy pulled out unplug it and start stripping some of the black loom away exposing the two wires. Blue is the positive signal and black is the negative signal. If you get the taps is described here -> (3M (http://www.altex.com/3M-Scotchlok-18-14AWG-T-Tap-Self-Stripping-Female-QuickSlide-Disconnect-952X-P149011.aspx)), tap the gray wire supplied to the black wire (The black wire is the negative coolant temperature wire), and a small white wire supplied in the kit to blue wire (The blue wire w/ tracer is the positive coolant temperature wire)

Ok now you got the temp sensors GTG. Next thing wire your fans. The fan on the passenger side of the car I set up for Fan one, and the other as Fan 2 for my setup. make sure you keep that in mind if you are running the wires through a sleeve later down the road.

Ok let's take a look at the fan controller now. The connections are as followed from left to right (On the Version C model): F1 (Fan 1), F2 (Fan 2), B- (Battery Ground), B+ (Battery Positive), S- (Temp Sensor Negative), S+ (Temp Sensor Positive), SG (Switch Ground), SW (Switch Positive), AC (AC Relay Trigger // Post 3 on the KA AC Relay, double check this as I did not wire it I'll explain later), & the last one IG (Ignition Trigger or any 12+v trigger, I used the Fan Low Relay in my fuse box as shown below)

Ok now comes the programming part. In the instructions it will tell you the fans will "pulse". Mine straight turned on, there was no flux in and out of power. So if yours just turn on and don't "pulse" don't pucker up your butthole just yet.

1. Disconnect power to the unit (B+ input).
2. Connect ground to the unit (B- input).
3. Connect the manual switch (SG connected to SW) wires together. I used a small piece of wire with two female spade ends for this part.
4. Connect the IG input on the unit the relay post show in the pic below:

http://i26.photobucket.com/albums/c106/mattack69/240/IMG_1862.jpg

5. Set BOTH rotary switches to "E"
6. Connect power to to the unit (B+ input).
7. The fan(s) will pulse / run according to the programmed setting above. Let them run for 2 minutes)
8. Disconnect power to the unit (B+ input)
9. Disconnect the manual switch (SG connected to SW) jumper wire.
10.The unit is now ready to operate normally. The same rotary switches you set to "E" will now be used to program the controller to adjust the turn-on points of the fan(s).

I'm running a Nismo thermostat so it opens earlier than OEM so I have my Fan 1 set for 175 degrees, and Fan 2 set for 195 degrees. Also I will not be running a switch so I did not wire that or the AC into this. So this wire up will be easy peezy.

So Connect the wire as follows:

1: B- Ground to the Chassis.
2: Fan 1 & Fan 2 Positives wire to F1 & F2.
3: S- to the Grey Temp Sensor wire & S+ to the White Positive Temp Sensor.
4: IG to the Low Fan Relay #3 hole I do believe (Just refer to the picture below) http://i26.photobucket.com/albums/c106/mattack69/240/IMG_1862.jpg
5: B+ Connect the battery wire to the battery.
6: Set Fan 1 on setting "A" and Fan 2 on setting "D". This will let you test that you programmed the fan correctly.
7: Once you have let the car warm up and the both fans kicked on shut off the car (The fans have a 30 second cool down feature, so they will run for approx 30 seconds and then shut off). You will also hear the controller switch off.
8: Set your dials to the temp you want each fan to kick on. Here are the temp / dial settings for the Version C controller:

Position Temperature (programmed setting B - I) *Voltage (programmed setting M - P)
A 150F 65.6C +50mV
B 154F 67.8C +100mV
C 158F 70.0C +150mV
D 162F 72.2C +200mV
E 166F 74.4C +250mV
F 170F 76.7C +300mV
G 174F 78.9C +350mV
H 178F 81.1C +400mV
I 182F 83.3C +450mV
J 186F 85.6C +500mV
K 190F 87.8C +550mV
L 195F 90.6C +600mV
M 200F 93.3C +650mV
N 205F 96.1C +700mV
O 210F 98.9C +750mV
P 215F 101.7C +800mV

Tuck your wires and I suggest you mount the controller by the fuse box with the spade connection down so water and stuff don't graze that mofo.

-do work.

I will link the video of everything running once it's uploaded to Vimeo..

*EDIT* link to video -> http://vimeo.com/24982088

[mattack69]

I'll post how the AC runs later this week when I hook it up.,

[shinmei-2006]

i know this is bumping an old thread, but i've had both fans burn out (at different times) within 1 year of buying. Mishimoto replaced them for free, but i didn't like the fact that they failed so quickly. Also with A/C these were not enough to cool the engine. Car would overheat. I have since bought an oem shroud and fan for my SR and will not look back on mishimoto fans for use.

[TheRealSy90]

^ I'm with this guy. Electric fans just didn't cut it in the Arizona heat. Went with clutch fan and shroud now, no problems.
