Well fellaz i'm hoping to add a life line to my Q's AT this weekend. Based solely on elwesso's experience w/ the B&M supercooler i bought one on saturday and it was delivered this morning. The item# i got is 70268, (please let me know if that the right/wrong one by chance). I've read and printed wes's installation guide from "The ORG" and I'll keep it close to me as i attempt the install. I'm not mechanically inclined, but i can follow directions and i do have common sense, so i'll give it a shot but i'll need some hand-holding. I hope to identify the fluid lines and routes before i start, and compare to wes's guide. What are the differences between the '94 wes's guide is based on and my '90. What will i/won't i see. Halloween is around the corner...are there any Trick or treats i need to watch out for?Outside of the B&M kit, is there anything else i need to buy...except cold beer guys My mechanic here in macon quoted me $60 to install it in case i get stuck.So between now and friday please share your collective knowledge.

PITO, I hope you have minutes on your cell buddy, cause i'll be calling, u know it!!

Youll notice at the beginning of my writeup there are 4 points highlighted..... There are only 2 on the 90... So instead of cutting 4 lines and getting rid of the filter, you only have 2 lines...

But other than that it should be nearly identical.. The metal lines that I showed will be in the same.....

You will find two rubber lines on the left (driver's) side of the radiator going to nipples that feed the factory cooler in the end tank. Follow them back to the metal coupling below the oil fiter area. This is where I tapped in... I put my cooler between the radiator and condensor in front of the auxilary fan - pretty much in the lower right corner of the radiator. I can't find the member's ride section to upload and link photos now, but I took some pretty detailed pictures that I can email to you if you like. Now would be a good time to buy and replace the foam inserts that keep the air flowing through the radiator vs. around the sides... For completness I capped the factory cooler with some rubber plug covers from Home Depot, just in case you ever want to use it again.

Never, ever "get rid of" any external filter in the transmission line unless you replace it with a new one.

Nissan engineers do not play around attaching excess parts for the hell of it.

I had some pics in the members ride of the cooler I put on my '90. Not sure where they went in the move. If you can find them they might help.

Most folks put it between the radiator and the condenser. What's nice about the 70268 is that there are flanges on the top and bottom that you can drill through to fasten it to the bottom flange on the radiator. This allows you to use sheet metal fasteners to bear the entire weight of the cooler and not have to worry about the plastic zip-straps getting brittle and breaking, or of fatiguing the thin radiator coolant lines.

Anybody ever think of putting in a transmission intercooler? I was thinking about it, and it would be a great thing to do. And you know me, I could make my own, so it would be cheap.

I went ahead and emailed them last night... did you get them yet? The foam inserts are available from http://www.everythinginfiniti.com (or your local dealership). "Q1" had nothing (but the radiator was replaced a couple times during the transmission replacements... and "Q2" had rubber flaps that should keep the air directed... in any case now it has foam and rubber flaps.

Got it coach! (the Pics)Ok here's where i am, today i decided to just ID everything and familiarize myself with the task and make sure i can mount it correctly. I hope these pics upload because i seeing something a bit different than i expected.

http://pictures.sprintpcs.com/...eName=

If you can see this pic, then you'll see a metal line running between the radiator and condenser. What is that line?

http://pictures.sprintpcs.com/...eName=

cahttp://pictures.sprintpcs.com/guest/guest_book_album.jsp;jsessionid=aaagw9VXlvlKMF?machineid=wmtp001&invite=hEq22o5mhmYGQh2zhQFL&page=3&play=stopped&invite=hEq22o5mhmYGQh2zhQFL&shareName=n

If you can see this pic then you'll see how far the transmission cooler will go down w/ that metal line in there. It's almost flush w/ the top of the radiator and condensor. Is this too high up?I tried inserting it from the bottom similar to q90's setup and this cooler is too big to fit thru the gaps of the car's frame.

Should i loosen the hinges of the radiator to try to get it down there some more w/ the metal line in place. I don't think Wesso's '94 has this metal line based on how deep down his cooler is in the writeup pic.

Also the bolts, provided in the B&M kit dont fit the predrilled wholes on the rad. but that's minor!

Thirdly, do any of you tech's know for sure which transmission line is the return line, I've got only 2, both going into the drivers side of rad, is the line going into the top or bottom of radiator the return line.

The job don't seem very hard but i need to figure out this mounting thing....Please advise guys....

JT..... Very nicely done on the trnany cooler install...

I actually (no flaming) ran the hoses right across the foam on the sdies of the radiator..... Hey mine was shot so who cares!!!

That line is the PS "cooler", IIRC...

Just cut all the hoses from the metal lines coming from the transmission going to the heat exchanger, and install your new hoses to your new cooler..... New=good

I think your right on the money (pun intended) on getting this thing mounted, just cut off those little bracket things..... I actually kinda have mine wedged in between the PS cooler and the radiator... It actually rests against the radiator , and thats better I think ebcause that will keep it from flopping foreward...... In all honesty I think your mounting point is just fine!

It actually looks as if the line you speak of is sorta up a lot higher.. On my Q its about halfway in the middle of the rad and condensor.....

I really believe that the transmission cooler should be in front towards the bottom getting the most cool air possible. He lives in Georgia where it is always blazin. Mine is located (facing the vehicle) lower left. You can see it from underneath the car. It may require loosening the radiator but in the end it will be beneficial.

Here is why I usually go against this... However before I say this, ANY transmission cooler is better than the stock so really it shouldnt matter where you put it...

The main time you need cooling is when your in traffic... At a highway cruise you dont need much..... Plus if you live in a varied climate (indiana) you want it where youll get some warming in the winter as well as cooling.....

Putting it in between the radiator and condensor accomplishes all this... It does block the radiator a little but not much... At idle the fan draws air through and that keeps the transmission cool, and it also LIMITS the amount of cooling done at cruise... You dont want the transmission TOO cool.....

However, your point that he lives in georgia where its warm all the time is a good point.....

However the main point of all this IMHO its MUCH more important to have a trnany cooler than it is to worry about where you put it... if you saw Jesda has his behind the radiator... Probably not the most efficient place, but its a nice placement for his climate.....

I think JTmoney should just put it where he's putting it right now and be done with it.....

I think my problem or benefit (not sure which one) w/ this cooler and the placement options i have, is it's size. The 70268 is bigger than some of the other cooler's avail from B&M and won't fit thru the small air passages at the bottom of the car.

Is the heat exchanger the "portion of the radiator" the lines currently run into and out of now?

What about cutting only one line and attaching the return line to the cooler? Is it just my perogative or a positive to just bypass the "radiator" all together? (i hate the fact that i think this post already exist)

Also should i mount the cooler inverted so the inlet and outlet are downwards? I would prefer that if i cant find a way to mount it lower down.

Any other opinions anyone...?Thanks

Some have mounted it invernted, but I prefer to mount it so the inlets are up, that way leaks are easily detected...

In all honesty I think your making this too hard.. Just mount the damn thing and get it hooked up.. The difference is cooling (by mounting it in different places) is marginal at best.....

Might check Member's Rides under my name for pictures of various ATF cooler installations, including a B&M 70268 in front of the driver's wheel where it gets its own cool air and does not heat any other heat exchanger with its exhaust, and it is well protected from road debris.

So the general consensus is the B&M is the best brand around?

Anyone try the Perma cool line of transmission coolers?

do NOT bypass the stock cooler. The lines should be in place so that the aftermarket cooler is the last thing the fluid goes through before it returns to the transmission. Added cooling that way, and it's the RIGHT way to do things.

Thanks err'one for you time and advise. I completed installation and just keeping an eye for leaks and such. Really wasn't that hard, but it's all about confidence.

Anyways i did bypass the stock cooler or heat exchange or whatever you call it. Hopefully this add's life to my car. And hopefully it does provide enough cooling...what was surprising to me was the amount of heat infront v/s behing the radiator once the car it hot, it's like night and day.

While i was under the hood, i decided to inspect and clean air intake and throttle body...but in there was almost as new, the mesh filter infront of MAF had a thin bit of film. The throttle body itself was clean as a whistle. Thanks all who imputted...

Did you cut yourself installing the Cooler? If you didn't you need to spill some blood or your Q won't love you anymore!!

When you looked at the Thottle body did you push open the butterfly. This is really where the dirt would be. You wont really see it to clear but if you spray in there with throttle body cleaner you will see the dirt flow out in liquid.

Most Q owners completely bypass the stock cooler, and thats how you want to do it!
