AT radiator use in 5sp and for oil cooler????
Hey guy,I got a used AT radiator and put it in my 95 5sp,the AT radiator had two xtra holes for the AT fluid to go into the radiator to get cool down before going back into the tranny,I don't use that holes on the AT radiator in my 95 5sp.So I'm thinking CAN I USE THIS HOLES as for my motor oil cooler to cool the oil instead???If I can what parts(filter adapter or what?) do I need or have anyone try this out yet,cause I just want to have one less part to put into the car,thanx!!!

I was contemplating doing that as well. What temps does the oil get to? The coolant and oil would have to be pretty close in temps to make this work efficiently for both systems.

I think that's a GREAT idea.
StephenMax is running a HUGE RX7 oil cooler on his SC'd max.

I got my new Koyo for $112. But if you get a new rad you might as well get a manual one. I think the temp variance between the two fluids will comprimise the effectiveness of at least one of the systems. The manual is thinner and therefore lighter so the added weight of the seperate cooler won't be much more than the stock auto rad.

I don't think the weight on the manual rad will affect any performance on the FI car,LOL!

I installed a KOYO OEM style replacement on my Sentra....it was very nice quality and drop-in.
I would get the KOYO "high performance" aftermarket version if you have the money.
Here is the difference OEM vs. Performance on the Sentra:

Well that's why I'm asking this question and see if someone have try this,if not I'll try it and see if the temp will improve or not.If the AT rad's thicker then it prolly cool better.

Koyo doesn't make a performance version for us. I30Krab has a custom Griffin radiator. I kinda looked into that when I needed a new unit but it would've been hella dough; like $500+. Many people say its not much to keep your engine running cool. That maybe true on cars with pathetic stock cooling systems like RX-7's. But the cooling system of the Max is one its strongest assets. Never once have I overheated my car. And the few accounts of people overheating is due to improper maintenance of the system(Low coolant, busted fans or t-stat.) For that matter I rarely see coolant temps above 190 degrees even when pushing very hard. Only when idling in a parking lot do I see 190's or 200's.

the tranny fluid gets hotter than the coolant too. if it didnt then there would be no need for it to go into the rad. if it didnt get hotter than the coolant then the radiator would heat it up and not cool it down. plus you have to remember that air passing through is what cools the radiator not the coolant so i still think that it would work awsome as an oil cooler...plus its pretty big so it would cool it pretty efficiently.
#17
I always heard that ATF should never be more than 180 degrees. Lets just settle this by saying that it won't be as effecient as a dedicated oil cooler but it will still work.
Thats another thing. What is the volume of the ATF cooler section? There is no way to tell from looking how big it is.

if you want to try to modify a ixisting radiator to it a maxima the closet one i found was a koyo high performance radiator for a s13 silvia. that is about as close as i have seen.
or you can go with the griffin radiator that i got and have it be a direct drop in. your choice.

Was the S13 rad width any less? If so, how much?

yeah I had a auto tranny but now im 5speed and boost and the AT cooler is just sitting their and I thought about tyring this a while back. Now with summer coming and the heat we get down here in S.C. I think im going to try this.

i didn't measure it i just kind of eyeballed it cause it was installed in my friends car already. plus i didn't really give it to much though. i do have koyo s13 rads in stock here at work so when i get a chance ill measure the dimensions.

griffin rads are mid 400 i believe.
its not made for a auto matic.
koyo race radiators are not made for auto either. s13 radiators are smaller physically the vendor i bought mine from physically compared the two.
if your looking to do something like what hal did then i can unsterstand why you woud want to use a different radiator. if your looking for something just to use as a upgrade that will fit right in.
trying to give yourself an option will be more trouble than its worth. (im talking about a radiator nothing more.)

Well the whole point is to see if I can use the AT radiator from the auto,as I already had it in the car,and seeing there was two connector for the transmission NOT using,so I just want to see if there was anyone out there using it as an engine oil cooler,all you will need is the adaptor and you have your self a oil cooler,I know some of your might argu,but to me one LESS cooler is better.I'll try it out anyway,but money was a bit tight right now,after the turbo go in and everything all work out,then I'll start buying temperature gauge,sensor and definitly try it out and see.Well can't beat a $45 used radiator right now,LOL,but in the future I might going to get a griffin and a seperate oil cooler when I got more power to the wheel.
