yeah I checked a while back and there are no numbers on my mount. mine is off of heavy construction machinery (excavators, motograders, dozers, etc)
but on summit there a few are universal kits that will do the same, just make sure to use a hydraulic filter which is much more fine at filtering than a normal oil filter. mine are WIX 51551(IIRC) but it is also a larger ID for the threads than a normal filter. search on summit for "remote filter" and there are a few kits under $40

way cool, does anyone know what parts i'd need to mount this B&M cooler to my 4L ZJ that had no factory tranny cooler? (uses just the radiator cooler)

**corrupt143** · 03-02-2007, 11:47 PM

Parts 1, 13 and 7 in the pic below. And some bracket to mount the cooler.

yeah number #1, #13, and 2x #7's and the u shaped bracket should already be in there so to attach to it it is easiest to just get 2x of the rubber pipe clamps like shown in the first pic of this thread

**kd6zxe** · 03-03-2007, 12:33 PM

What about air flow problems through the radiator, now that you've blocked a larger portion of radiator? Also the new cooler may have more tightly packed fin area but for that reason it probably has a higher resistance to air flow.. anyone notice any higher engine temps as a result?

**DJJordache** · 03-03-2007, 05:16 PM

there was no difference in engine temp for me....and it is not "blocked" it still flows air through it.
I guess you could say it could possibly be an ounce cooler since the trans fluid runs through the radiator also that if the transmission fluid is cooler then the engine coolant might not be heated up as much by the trans fluid

stretching I know haha

**kd6zxe** · 03-03-2007, 05:45 PM

these thermal problems are so much like the chicken and the egg..
im going to try to get ahold of perma-cool and see if one of their maxi-cool juniors can be adapter for both oil and tranny, or see if they even fit in a jeep zj somewhere.. http://perma-cool.com/Catalog/Cat_page13-1.html
one of those with a fan mounted *somewhere* protected would be choice..

**LouisianaZJ** · 03-03-2007, 09:44 PM

swampy has a cooler just like that for his tranny cooler, i think it is permacool

**unforgiven** · 03-03-2007, 10:43 PM

guy almost has to wipe his chin lookin at that perma cool page. damn there be some good sheeit there!!!

**kd6zxe** · 03-03-2007, 11:27 PM

agreed

**kd6zxe** · 03-05-2007, 07:11 PM

So the big question..
you fit a 11" x 7.25" x 0.75" tranny cooler in the stock location.
do you think a 12.5" x 10" x 3" would fit in that same space?

**kd6zxe** · 03-05-2007, 08:28 PM

who is swampy and where do i get ahold of him

**LouisianaZJ** · 03-05-2007, 08:34 PM

he is on the forum, but he did not mount the bling tranny cooler on the radiator. he put it in the back cargo area of his chopped ZJ

i think you should go for a 10"x12"x 1" cooler and mount it in front of the radiator

if you are concerend about airflow to the radiator, just space the cooler 1" away from the radiator and if will dramtically reduce the effect of the reduced airflow from the large tranny cooler

**kd6zxe** · 03-05-2007, 08:52 PM

Blargh

anyone with a B&M that can measure out 12.5 x 10 x 3 and see if thats feasible around the space their radiator is in?

**RBall151** · 03-07-2007, 02:32 PM

This is only for the ZJ right? I haven't taken a look under my WJ yet.

On my WJ FSM it states:
"An internal high capacity/high efficiency cooler is used on all vehicles these coolers are an oil-to-coolant type which consists of plates mounted in the radiator outlet tank. Because the internal oil cooler is so efficient, no auxiliary oil cooler is offered."

**kd6zxe** · 03-07-2007, 04:04 PM

What a load of blibbering, nobody can argue with me that more cooling isnt better!

"Because the internal oil cooler is so efficient, no auxiliary oil cooler is offered.""

**RBall151** · 03-07-2007, 04:37 PM

Is this only for ZJ's or will it work for WJ's too?

The 3" is way too deep. The 0.75" is the perfect size...any deeper and it would be too tight.

I installed the 11" x 7.25" x 0.75" a few months ago in my '95 ZJ 4L. To attach I used the supplied plastic-pulls through the air condition condenser as I was installing a new radiator so it was easy for me. If I had to do it again I would find the brackets that wrap around the A brace to secure.

I bypassed the radiator altogether, had no problem with trans slipping or bad shifts even in -6 degree weather. I don't think trans fluid could ever be too cool.

**RBall151** · 03-26-2007, 04:04 PM

Where can you get a mount to hold the cooler if your Jeep doesn't have an existing one on there?

Have any WJ guys out there done this?

**JohnnyV** · 03-26-2007, 04:34 PM

Got your PM RBall151!

My ZJ did not have a factory trans cooler.

As mentioned I used the plastic locking ties that was supplied with the B&M trans cooler. But it was a no-brainer as I was installing a new radiator so it was easy to run the ties through the AC condenser.

But I guess what you are asking is how to mount the trans cooler without removing the radiator. Somewhere in this thread there is a picture of a simple bracket the wraps around the A-frame supports and that gets screwed into the trans cooler. I might relocate my trans cooler and use that method. Any good hardware store would have the brackets.

Oh the pictures of the bracket is from the first post...that A bracket is part of the jeep:

**JohnnyV** · 03-26-2007, 04:45 PM

OK I see the clamps (I called brackets) are part of the original trans cooler. That's not a problem. Go to the hardware store and find a metal strap that holds up sewer pipes. The strap is about an inch wide and has holes every inch or so. Just cut and wrap around the A-Frame and bolt up.

**kd6zxe** · 05-22-2007, 04:51 PM

Hey I'm thinking about putting in the factory tranny cooler. I also have a hayden fan I want to install, so the bigger B&M cooler is probably too big to fit the fan and the cooler. DJJordache, I noticed you're in houston, to you happen to have a good chrysler parts supplier here? I guess I'd be looking at parts #1, #13, 2x#7, and is it #8 that is the actual tranny cooler? thanks

**nate** · 05-22-2007, 04:56 PM

Just get the thin B&M cooler, the 3/4" one, it's like $40. Some P Clamps, some hydraulic line, hose clamps and that's it. I wouldn't even waste my time with the factory stuff unless you can get it for cheap like in the junkyard.

**Cue-Ball** · 05-22-2007, 04:59 PM

The B&M one actually comes with a length of hose and hose clamps (not sure it it is long enough or not though).

I simply replaced my stock one with the B&M. One of these days I will install the stock one and use it as a PS cooler.
