How to cool down my motor

[thekawaii]

It's over 90 degree out there. I took my Silvia center grill out(i have jdm s13 fixed headlights). It helped littlebit on freeway driving. Before I put my turbo in my car (still waiting for SAFC... dang Slow shipping...), I read bunch of forums talked about cooling problem. I thought I'd better put some insurance before I put my turbo in. So I found some stuffs for better cooling. I found water lines for my Z31 turbo and radiator

http://cgi.ebay.com/ebaymotors...QrdZ1

from ebay, It's KOYO. Is this a good radiator? Is there any better radiator I can get? And i still haven't find any Elec. Fan...... +i'm not good at wiring stuff...What other stuff can help my motor to cool down? Oil cooler?

[Import_Ant]

those things will definitely help. shimming your hood can help, how old is your coolant? if you haven't changed your coolant in the last year or so I'd go ahead and drain your coolant and at a minimum, remove your stock radiator and clean it out. just take a garden hose and run water through the fins and clean all the dirt and gunk out. then when you re-install it (or if you get a new radiator) do a 70/30 water/coolant mix and add some water wetter. someone on here was running that setup for their coolant and claimed it helped them out quite a bit.

as for the radiator, Koyo is a good brand. for the fans go junkyard hopping. I know you can use a dual fan setup from an Altima or Integra. I'm sure you could use one from most FWD imports. just have to do a little trimming/bracket fabricating.

[turbo_lover]

well, you can wrap your down pipe, the "hot pipe" charge pipe, which goes to the turbo the intercooler. KOYO radiators are exposed to be nice, but i am wondering is it a single,double, or triple core one? i think Water Wetter does the trick too... pour it in your radiator I BELIEVE. not sure so id search B4 you do it. (cause I would feel like $**T if i were to blame for the blown motor cause i was stupid.)

If you can stand the heat, take out your a/c. You'll get more cooling flow to your rad and your engine will run cooler without having to turn the compressor.

Helped out my car a lot, but then I never used the a/c anyways.

[Jookmasta]

i have just recently purchased some electric fans so i will let you know how it goes.

[onosqv]

koyo is good, elect fan will help a lot. that koyo is an "okay" stock replacement. I would go w/ the full aluminum dual core for even better cooling, especially w/ turbo.

I personally run koyo full aluminum, altima fans (taurus fan will work as well i believe), and greddy mss controller - you can use a cheapy one but it's hit & miss w/ that plus you won't really know what's going on, had my hayden crap fail on me twice.

I can give you some tips on wiring up the electric, I'm in the OC too, so you can check out my stuff before we do ur turbo, haha. I also found a shop that sells the greddy mss for really cheap. Just hit me up on aim: agentsonic02.

the stock cooling system shouldnt have any problems keeping the engine temp normal.

lately its been over 90 degrees here a few days a week. my engine temps usually are about 183 degrees. a friends car that never had the cooling system touched reaches high 190's. i just have a mix of about 75% water and 25% coolant currently

[sunnys14]

nismo thermostat helps ALOT!

[hek1620]

my car is overheating everyday because of the damn heat out here when i use the a/c. how much could u look to spend on altima fans at a junk yard? also are the aftermarket ones way better or more or less the same crap?

[Structure240sx]

altima fans from the local junkyard from me are $30. they actually compare quite evenly if not better than aftermarkets

still you shouldnt have overheating problems with everything is working correctly.

try unbolting the radiator and lean it back to see if there is any dirt and debris built up on the fin. even if there isnt take a scrub brush with soapy water to the radiator and an air blower (from an air compressor) to blow out any dirt between the fins. you will probably see smalls clouds of smoke come out.

[Jookmasta]

what is a greddy mss controller? is it some kind of thermostat switch? i was thinking of using a thermostat switch to control one of the fans in my dual fan setup. my plan for the other fan is to just wire in the plug from the stock electric a/c fan to it so that when the a/c comes on, both will run then.

[onosqv]

Sweet, $30 for altima fans, can't beat that - I got mine for $50 and that was a steal, haha.

Yea, like Structure said tho, if stock system is working as it should, you wouldn't have problems. You could try a coolant flush & fill first and see how that goes. Make sure you flush right and get all the air bubbles out tho.

As for the mss, it's a "universal" controller, meaning it can control your fans, your alcohol injector, water spray, etc, etc. It is like the hks fan controller, but w/ more functionality since you can base things off temp, rpm, speed - I think also boost but I don't know how to wire that one up yet (instructions are in japanese).

Another install guide (less pictures - easier to print out) from the guys I bought it from:http://www.frsport.com/greddy-multi-swi ... p-524.html

[thekawaii]

so.. KOYO is "okay" oem replacement.. hmm...

I resently flushed my old radiator water. (Green + little brown color)The engine is fine, it just heats up too great in the morning and in highway driving at 12~2 pm.

oh yeah, any altima elec fan works fine? or any year?Right now, I'm trying to put water spray line on my SMIC/Radiator. Pump, I'm just gonna take one out from other 240sx.And about oil cooler, i found first gen. Q45 oil cooler. (I'm not sure if it's an oil cooler, it's in the driver side fender with nice elec fan on it. ) I'm gonna figure it out.

Sturcture is right. Its been well documented. All you're doing is inviting problems by putting aftermarket fans on our cars. Just keep the stock fan & shroud on the car. If your're still over heating then you have another problem and an electric fan won't help your problem.

[onosqv]

From another post: http://home.satx.rr.com/nissanweb/RadTest/RadTest.htm

[duncan351]

I read that thread as well however the E fan that was recommendend wasn't cheap. The altima fan is a great alturnative however you have to know what your doing as far as wiring goes which can be a challange for some users doing it correctly without burning up relays, wires, electric fan motors, etc...

The best approach is to keep the stock fan. Get your turbo kit right first and in good working order. Then maybe work on your cooling system.

[hek1620]

turbo brings more heat to the engine doesn't it? so i think u should take care of cooling first. thats what i'm doing. i have almost all my turbo components but i'm holding off 'till my car is running cool with no problems. just my suggestion.

[Mustangs_Suck]

I got the koyo dual core radiator with a 12" flex-a-lite fan. running 70/30 water/coolant with water wetter, along with my 3" thick intercooler. have absolutley NO problems running it in 100 degree heat as far as overheating goes.

[duncan351]

Go run it on a road course for 30min session them come back if you yeild the same results.

You can make a very effective water spray/mister for under 45 bucks. Very effective and used alot in auto-x. I'm using one on my IC since it's 110 here all summer. Somthing cheap ands easy.

Shoot me an email if your interested in any details. [email protected] I'll post up the info if anyone wants it as well.

[thekawaii]

Yeah why not!?!?! thanks

[thekawaii]

wow. great article... But surprised... stock and koyo radiator, only 10 degree diffrence for 100 bucks... I guess I'll just buy air cooling panel for 20 bucks since 100 dollar radiator only makes 10 degree difference...

Things to get:1. Oil cooler: one sandwich adapter, 2 hoses, one oilcooler (from FC RX-7 or Q45)2. Air cooling panel (no Koyo radiator)3. Turbo water line: 2 hoses, 2 T adapter.

About the oil cooler, do I have to upgrade oil pump too?

brokeAs240sxAre you really gonna help me install my turbo?

Yes, the more DIY articles the better!

[thekawaii]

okay. i got the water pump. how should i hook it up? i still want to keep my window washer though... I have 2 motors, means i need extra switch to turn on the i/c water spray. i'm gonna get an extra water tank filled with cold water. (no alcohol. it's just too dangerous)

And another question, is it possible to make it like "automatic water spray pump". like when the engine or i/c whatever hit the pre-setted temperature, motor starts to spray water over it? (sorry i just like automatic and sh**)



looks like if i make it manually, connect pink 2* to #17 (switch between 2* and #17). Connect green 1* to green 1. then i can use both window spray and i/c spray...

but how do i make it "automatic"?I'm really bad at wiring and stuff..

[onosqv]

I'm really bad at wiring and stuff..

Like I said in the other post, you can use a greddy mss controller - will take some creativity to be set to boost since there are no english instructions, haha, but it's suppose to support it.

Speed & rpm & temp are in a freshalloy article (search for greddy mss).

brokeAs240sxAre you really gonna help me install my turbo?

Fo shizzle my nizzle, hahaha. Help you yes, install it for you, no - cuz I don't want to be responsible for any spontaneous engine explosion .

Of course, I hope you will already have your fuel rail part & oil pan dropped and all before you do it - or we will probably need to split it into a few weekends or so. I'll be doing my fuel & pan soon, hopefully, so I'll be able to help a little, haha.

And uh yea, there needs to be the most important tools there - pizza & beer. mmmmm.

[thekawaii]

editted my post. i didn't know you'd reply this fast. LOL

[onosqv]

I'm on aim if you have questions: agentsonic02 - watching The Office marathon, hahaha.

[thekawaii]

I figured it out myself... for the first time. HATE WIRING!!! I don't even remember how many fuses i burned for nothing.

I guess i'll just do Manual spray for now. wait! i didn't even put my I/C in yet! too many plans..

I don't have aim. surpringly, all of my friends use msn. don't know why.

i run 15psi daily currently on pump gas, no issues

/\/\ r u running a stock radi?
