Dickensheets Posted April 22, 2006 Share Posted April 22, 2006 Looking for a source of supply for those of you running with these. Also, is it just more surface area which makes them better, and do they mount in front of the radiator like on big trucks? rd Quote Link to comment Share on other sites More sharing options...

lmdew Posted April 22, 2006 Share Posted April 22, 2006 Visit your local junk yard and look at the old trucks. Lots of great heavy duty coolers < $10 usually. Just make sure you clean them out well! Quote Link to comment Share on other sites More sharing options...
2X2KOB Posted April 22, 2006 Share Posted April 22, 2006 SO how do you install one of these - make it so the fluid goes through the factory radiator first, then the external cooler, or the other way around? And how do you tell which direction the fluid flows through the lines? Quote Link to comment Share on other sites More sharing options...
Ranger83 Posted April 22, 2006 Share Posted April 22, 2006 Most radiator shops stock them and don't charge much to install. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted April 23, 2006 Share Posted April 23, 2006 make it so the fluid goes through the factory radiator first, in my oppinion it is best to completely bypass the piss poor factory side tank lines and just use the dedicated cooler. a stand alone cooler will far exceed the cooling capacity of the radiator tank. and no need for the extra hoses, routing and clamps, just something else to leak. frankly i run one entire hose from the transmission to the cooler, just to have fewer clamps. some Subaru's have a hose to a metal line to the cooler. i remove the metal lines and install one piece rubber hose. don't think that's necessary but fewer clamps are better for me. Advanced Auto parts has a complete kit for $29.99, i think that's what they run and that's the smallest size they have. the smallest size they have is more than adequate for any subaru. they come with plastic things that poke through the radiator, but i don't use them. i don't like messing with my radiators and you have to cut them off to remove the radiator. i use zip-ties and tie them the end of one coil to the center support where the hood latches and use another on the other end by the hoses to hold it in place and the hoses where i want them.

2X2KOB Posted April 23, 2006 Share Posted April 23, 2006 Is it possible to "over-cool" the transmission fluid, or is this a case of, the cooler the better? I'm thinking about zero degree winter days. Quote Link to comment Share on other sites More sharing options...
Andyjo Posted April 23, 2006 Share Posted April 23, 2006 nah, it just builds your tranny some character i'll be doing this this summer i think... when i was offroading the other day my 4EAT was PISSED OFF, i had the center clutch pack locked up, and i was giving it alot of nut, in some torquey situations... at one point i was going up.. the motor was at about 3.5-4k rpms.. and the car wasn't moving.. no problems with traction.. just a large lack of torque..... think i may have to change my fluid again :-\ Quote Link to comment Share on other sites More sharing options...
Tbird Man Posted April 23, 2006 Share Posted April 23, 2006 or your clutches and bands...that much slippage is never good for it. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted April 23, 2006 Share Posted April 23, 2006 the transmission fluid and transmission itself are designed to run at a certain temperature. running at the designed operating temperature should be your best bet and i can't imagine significant gains below that. overheating the fluid is bad and what you're trying to avoid.

99obw Posted April 23, 2006 Share Posted April 23, 2006 I bought a B&M SuperCooler from Summit Racing. It has a viscosity index-based thermostat designed in, so it's supposed to not overcool the fluid. I will most likely be plumbing it in after the cooler in the radiator.

According to the tips on etrailer's website, no... "Tech Tips: Transmission fluid can not be over cooled, but it is critical in extreme cold conditions to allow the vehicle to warm up before driving. " (bottom of page): http://www.etrailer.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=E&Category_Code=TRAN It would be nice to have a bypass built-in to go around the cooler in the winter months here in the north.

2X2KOB Posted April 23, 2006 Share Posted April 23, 2006 Maybe that's why some people run the new cooler in series with the existing radiator trans cooler - puts a little heat into the fluid on really cold days. Quote Link to comment Share on other sites More sharing options...
