I will be installing my B&M super cooler tomorrow just a quick question if I'm going to by pass the radiator all together does the flow pattern matter to the cooler and back to the tranny?

SomeGuy138

If I was you I wouldn't bypass the radiator,seeing that you live in Maine and all it will help it get warm in the winter.

would you happen to know the flow pattern by chance for out of the radiator?

This should help.

thank you much appreciated!

To be 100% sure of flow routing, follow the out line from tranny.
AW4 fluid output is forward line.
Return flow is rear line.

X2 on using stock cooler in radiator for your climate.
If you like, we can get into discussing the reasons to install the aux cooler before the stock cooler..
FYI. if the B&M cooler is 'plate-fin' type than it's inlet/outlet can not be installed pointing down, sideways or up.

If he reads all of the trend that i linked him to it will tell about everything he needs to know.

SteveMongr

Including installing it upside down as the thread owner did?
I was replying at the same time as you so did not see your link until after.

so if I'm looking for the cooler to be installed after it goes through the radiator and the return is coming from the top line on the radiator I would splice that line make it go into the cooler then out of the cooler back to the return line on the transmission?

SteveMongr

Correct.
Also a good time to install a temperature gauge if you wish.

awesome well thank you for the help much appreciated!

You're Welcome..

The guy in that trend is also runing a OCOD oil filter .Not that i have ever had bad experience with one but i have see what them things look like on the inside and i will never use one lol.

Posting a diagram to go with this thread...
edit;My 1996 has the same routing but I'm unsure if the part numbers are the same.

B&M coolers are made by LONG Mfg. which also makes Tru-Cool stacked plate coolers. Per the FAQ at the True-Cool web site, the stacked plate cooler inlet/outlet can be mounted up, down, sideways....makes no difference.

We installed a B&M #70264 cooler and I called B&M about the inlet/oulet mount direction......the B&M engineer said disregard the instructions that came with the cooler and mount however I wanted....up/down/sideways. The B&M cooler has "LONG" plainly stamped on the mounting flange.

B&M says for max efficiency, mount their auxiliary cooler inline with and after the factory cooler. If u r going to bypass the OE factory rad cooler, I would strongly recommend installing a tranny fluid temp gauge with the temp sender mounted in the forward/hot line and as close as possible to the fitting on the side of the tranny.

FAQs at the True-Cool website:

What is the difference between “tube & fin” and Tru-Cool coolers?
A Tru-Cool cooler has many plates for the ATF to flow more efficiently. It also has more “live” surface area than tube & fin which further enhances cooling. Finally, though both designs are made of aluminum, Tru-Cool coolers are much more durable due to their design and manufacturing process.
How can larger tube & fin coolers offer less cooling?
Bigger isn’t always better. Tube & fin designs are inefficient and have a lot of dead space, while the Tru-Cool cooler’s stacked plate design puts most of the oil close to surfaces that are in contact with passing air. In fact, when it comes to cooling, the Tru-Cool cooler is up to 30% more efficient than less expensive tube & fin designs.
What cooler should I use for a diesel application?
In most diesel applications the transmission line is large. The cooler’s fittings should not be smaller than the lines. The smaller lines will restrict the transmission fluid flow.
The fittings supplied to not work with my application, what do I do?
We have supplied fittings for the four most common applications. Compression fittings can be purchased separately from your local distributor.
Part numbers: 735-9139 for 5116 lines 735-9140 for 318 lines
Where should I install the cooler?
If possible, locate the cooler in an area where it will be exposed to ram air. This helps maximize cooling. Install the cooler in series and downstream of the radiator in-tank oil cooler. This maximizes heat transfer and decreases transmission warm-up times in colder weather. Most OEM installations are plumbed this way.
How should I mount the oil cooler fittings?
Fittings can be located up, down or sideways. This advantage, plus their compact design, make installation of our coolers quick and easy.
Should I disconnect the radiator in-tank oil cooler when I install a Tru-Cool cooler?
Wherever possible do not disconnect the in-tank oil cooler. It offers additional cooling and helps preheat the transmission. In colder climates the in-tank oil cooler should never be disconnected from the system.
Will putting an oil cooler in front of the raditor increase tbe engine operating temperature?
Not normally. Putting an auxiliary oil cooler in the system decreases the temperature in the radiator in-tank oil cooler and this in turn puts less load on the radiator. From a total system standpoint, the engine operating temperatures should vary little from where they were before the oil cooler was installed.
Will installing an oil cooler affect my customer warranty?
It could, depending on which cooler you install. Vehicle manufacturers do not normally approve of the installation of tube & fin coolers since they are very flow restrictive as opposed to LPD oil coolers which are virtually the only cooler now being used for OEM factory installations. Contact your local dealer for approval.
