radiator relocation

[weissguy]

I swapped a 2jzgte into my s14 and it has barely any clearance between the radiator fans and the front of the engine. Its so close that I think the air cavitates and is affecting the cooling efficiency of the fans.

I was looking at the car and I think that I could re-locate the radiator underneath the radiator support area. Has anyone ever seen this done before? It would move the radiator forward a good 3 inches or so.


Tips would be helpful.

[Sileighty_85]

either that or put some pusher fans in front of the Radiator

[ill.]

Air cannot cavitate.

But it will be sucked straight toward the engine and be going nowhere.

[LUCKYxS13]

What I've seen some people do is cut the rad support and move the rad up a little. But im guessing you won't be into cutting the rad support!? Then again stick the rad underneath the rad support would be a good idea.

[weissguy]

I am willing to u the radiator support if necessary. The car runs at a good temp and does not overheat but I need the extra space to make it more efficient.

Another problem I have been thinking about is the location of my condensor if I move the radiator...I guess I may have no option but to leave it where it is at. are pusher fans as efficient as puller fans?

[thefro526]

Chasebays sells a rad that fits in the core support.

Should net you about 2" more clearance.

[LUCKYxS13]

Personally, I think pushers block air flow when driving on the highway or any road in that matter. Also when people cut there rad support, I didn't see them do anything to the condenser.

My pushers work just fine with my RB, also still have the A/C condenser in the stock location

[Slo_240sx]

I am also looking to move the radiator forward. My Turbo LSx S13 likes to get hot because it now has a 4" intercooler in front of of the radiator and a 2.5" crossover hotside behind it. I was thinking about notching the top of the core support and notching in between the headlights to make a nice seat for it. I'm going to go stare at it more today.

[Slo_240sx]

Bumping this thread...

I've been staring at the core support for a while now. It looks like you can notch the lower crossmember of the core support. I am thinking about drilling out the upper support's spot welds and using M8 bolts to fasten it back on. I'll get up pics once my Flexalite fans come in.

[2.5T_/<ouki]

I have just the solution for you. You can do the pushers, however i didn't go this route and i too was faced with a situation similar to yours. Let me snap a pic for you. Mine is in the radio support.


EDIT: Here are some pics i just snapped of what mine looks like. Please excuse the dirtyness :P. Been working on her lately and no time to clean her off!

I'm in the same boat with my RB25.

1. Chasebay radiators.....not gonna go that route, no way i'm paying $400 for a radiator unless it's made out of gold.
2. Cutting looks like shit and i'm wondering if this affects "flex or geometry" of the car?

[Mitsubayati]

I like 2.5T_/<ouki (http://zilvia.net/f/members/2-5t_-ouki.html)'s fix better than The chase bays one because it keeps the radiator at a higher point in the system.

Lol at the air cavitation comment. That's a fluid property.

Did you try fitting a clutch fan in there? What kind of mounts are you running?

I'm on stock r33 mounts with an r33 cross member and my steering column is an issue as well....not quite sure how to fix it besides doing a custom elbow...

I am also on r33 mounts w/ r33 cross-member. You need to get a Psyko performace elbow. They run about $200 picked up; it did the trick for me.

Look at how thick it is (no homo). I heard they do work fine on RB's. I tried contacting PSYCHO! (Syko) Performance and they never responded - guess they don't need the business in this economy. If I can't find one soon i'll just have a friend weld one for me....should be a fun project.

Btw, nice engine bay you have, what kind of tune you running?

I hope so, I'm putting in a LS1!

[jdm styles]

im also in the same boat i have a 1jz in a s13 and want more room and cool temps .... i use the car mostly for drifting so theres not always a good straight through air flow coming at the rad ! was thinking v mount . cant find too many pics with this setup though

Gotta move this guy forward to fit some puller fans. Pushers aren't cutting it with a 4" intercooler and a 2.5 hot pipe behind it.

Here ya go, AFC-80107N from Summit. I think I'll have to run a surge tank to get it to bleed right, might get away with just putting a rad cap in the upper rad pipe but it's iffy.

[EnemyS15]

For those who have the radiator tucked under the rad support and in front of the condenser... Does it effect the condenser at all, cooling difference since you have a thick core in front of it now? I am considering buying the chase bays rad for my RB25 in Jan.

Ps unrelated to the rad, but Cavitation is also used in terms of "air" when talking about ballistics. The formation of a cavity cause by pressure around the bullet when it penetrates the body. Had to learn that during my Paramedic course.. Just my shining moment to be that guy lol

I'm going to slang my Altima fans and radiator to swap in this radiator + r33 clutch fan.....

[Fred Allen Burge]

No problem, glad to help out.

has anyone on here done a rear mounted rad to move some weight back?

OMFG, I think i've seen that!!!! It was on a track car in the classifieds section. The car was done like no other 240 i've seen. Can't find the thread now....

[karl wasabi]

I have an RB20 and I was running into cooling issues. I wanted to run the Taurus fan, but there was no way it was going to fit behind the radiator. I've been into a few accidents so I ghetto fabbed a "tube" front end.

DON'T HATE!!! LOL

[Fred Allen Burge]

That doesn't look bad dude! Might cap off the ends of the tubes with some squares and maybe gusset the 90 degree spots for a more pro look but overall I think you pulled it off just fine.

[mantas]

Yeah i kinda dig this tube look,its got a bit of ugly and beautiful, dont know how to explain, but im sure its practical. Lol

Are you running a stock clutch fan, or is that some big electric fan?

Thanks, Bardabe (from this forum) helped me out a lot with it. We literally did this the night before a ASB, so it's kind of a hack job. haha.

Mostly ugly! haha. It's a Ford Taurus fan. It's supposed to have one of the highest CFM ratings of any electric fan out there. They are running the same fan in Fredric Aasbo's TC.

[mantas]

Well i've decided to cut my radiator support and try and squeeze in the clutch fan with the stock r33 radiator and shroud. I want to go this route so i can get rid of a lot of extra wires. I'm hoping to get this done this weekend or the following. When I do i'll try and keep my iPhone handy for some kind of a write up, it's overdue for us RB guys. If the stock radiator does not workout i'll make more room and squeeze in my alluminum radiator. Wish me luck! HAHA.

[mantas]

Well i cut my radiator support shoved the clutch fan in - pics tomorrow. And my problem nowis the stupid thing wont get to normal operating temperature. Went for a canyon run and nothing.....im thinking may be my car does not have a thermostat? Anyone have any ideas?

For those who have the "tucked" radiator under the radiator support how is it working on your RB/JZ/LS car's?

I've been having some cooling issues with the 2J swap and have been considering the Chasebays or the AFCO one that was posted in this thread, but just wondering how well its working.

[C. Anderson]

No problem, glad to help out.

It will be enough to cool the motor. This rad is a dual pass and cools much better. I bought this same radiator, with your help Fred, and thought it might be small. I filled my koyo with water and emptied it into a bucket then I did the same with the Afco and the afco held maybe 4 cups less.

I am going to be using a remote fill/reservoir and should have my car running and on a dyno in the next two weeks. I have an ls1 and a greddy water temp gauge for accuracy. I will post up more info when I find out.

By the way guys, car runs like a champ with a z32 thermostat. Someone suggested to run a single pusher but that would be overkill. It takes me a long time to get it to normal temps. In the canyons it it took a 3hr beating and not a single problem. I just wish I would have done this mod sooner.

[C. Anderson]

Its nearly done.

Thank you!!!! This is exactly what iv'e been looking for. And its not a $400 dollar price tag like chase bays

[Matej]

Sorry to bump this thread, but those of you with the Scirocco radiator, would you happen to know what thread size and pattern this plug on the bottom happens to be?

http://images.esellerpro.com/2422/I/428/6/Golf%20MK1%20MK2%208V%20Radiator%205.jpg

I own a different brand, and unfortunately it did not come with a plug for the temperature sensor hole.
Would it be beneficial to use a magnetic plug?

[Jus Skott]

I'm just a cheap jew and shimmed my hood.
allows air to be thrown out over the windshield so it just stay in the bay.

[C. Anderson]

My Afco was NPT. Don't know what size exactly. BTW I've been dailying the car for a couple weeks and this setup cools very well.

[Matej]

Thank you, but luckily I found the plug. I almost threw it out with the packing material. :)

[PeaceOnesxWai]

Skip the fans and run a electric water pump.. You wont ever have to worry about air flow to your radiator. Its less work then having to fabricate a bracket to relocate your radiator.

[Sileighty_85]

Just to show ya'll You can install Fan's, Condenser and Radiator without modification to the upper core support

[blessedhellrider]

think i seen some where ,that pusher fans are 20% less effective than puller . so dint cheap out on the CFM factor!

something like 400+ HP needs 3500 cfm or more. the ford clitarus ,I'm meant "taurus" has a 4000+ CFM puller ,don't know if ya can reverse.

[ch1873857]

has anyone tried mounting the clutch fan on the other side of the clutch sat the fan almost touching the the crank pulley. my radiator is in stock location with a little room to spare

[Matej]

Been doing that with all the clutch fans I have had.
It really only gives you a centimeter or so, but I suppose even that is something to one pressed for space.
I just do it for looks. :)

[ch1873857]

for me it was the difference between clutch fan and stock radiator location or some crazy tilted setup.

Look up (all in fabrication) on facebook.........he's one of the original innovators of the tucked radiator craze at least in the honda world. His prices are spendy but the work is amazing. He offers a tucked radiator, ac condensor, and backdoor intercooler all packaged together be warned its pricey but the quality and workmanship are there.

[cole d]

My Afco was NPT. Don't know what size exactly. BTW I've been dailying the car for a couple weeks and this setup cools very well.

Did you build the shroud for that? I installed spal pushers on my car and really wish I would have went with pullers and a tucked radiator.

Moroso 63745 Radiator Hose Filler Inline 1 1/4"

Bought this same filler as well, however, while the outer diameter may be 1.25" on everything, the thickness of the walls on the stock radiator, 16V/Scirocco radiator, and the filler all vary, thus resulting in different inner diameters.
The inner diameter of the inlet and outlet on the stock radiator is 31mm, while the 16V radiator is 28mm, and the walls on the inline filler are really thick, and so the inner diameter is only 26mm. Will it be safe to use?
