dneumannjr Posted April 15, 2006 Report Share Posted April 15, 2006 I order the B&M Cooler (part# 70297) and have started the install this evening. Just need to get some wiring in and it should be set to go. The question is I am going to go with some nice AN connectors and probably braided stainless steel lines to replace the run from the cooler to the trans. So this brings me to my fist question. Can I bypass the run to the radiator and just run from the tranny to the cooler? I am not really sure why it runs to the radiator then through the cooler and then back to the trans?? The other question is what is the size of the threads at the tranny 1/2 NPT or 3/8 NPT?? I just need to know what size connectors to order it's 1/2 NPT at the cooler but the stock cooler the connectors looked to be more like 3/8. Thanks gents will have pictures of the install tomorrow it turned out pretty good. Laters Link to comment Share on other sites More sharing options...
dneumannjr Posted April 15, 2006 Author Report Share Posted April 15, 2006 Here are the pics of the install. Pretty easy not to hard really. Do not mind the hoses right now or the wiring this will all be cleaned up this weekend after I get my new lines. That is as soon as I find out the thread size on the stock lines at the tranny or the radiator. They all look to be 3/8 NPT. Or the could be 1/2 but that was what was at the B&M cooler and it looks much bigger than the stock fittings. Any who here as some pics as it sits now: Here it is with the stock cooler removed: Just a little bit of a size difference :O See size does matter Top bracket in: Bottom Bracket in: Cooler Mounted in place: Cooler mounted and piped in. Hoses will be replaced with braided or hard lines: Switch is in. The cooler has a thermostat that turns on the fan at 170 degrees. I wired it up so that I could turn it on manually with the car on or off. The switch has an LED and the LED next to it is an indicator. When I have the switch on both the LEDS are on. When I have the switch on and the thermostat has activated the fan just the LED to the left comes on. This way I know that it's on and working. Kinda cool at least I think Switch on fan working: Link to comment Share on other sites More sharing options...
trickmob Posted April 15, 2006 Report Share Posted April 15, 2006 Do you have your cooler upside down . Link to comment Share on other sites More sharing options...
04CHASE Posted April 15, 2006 Report Share Posted April 15, 2006 i was looking at tha cooler for a while very nice piece. Why did you mount it like that though? Link to comment Share on other sites More sharing options...
BenKey Posted April 16, 2006 Report Share Posted April 16, 2006 I think it may work better flipped around. Nice pics. Link to comment Share on other sites More sharing options...
Holty Posted April 16, 2006 Report Share Posted April 16, 2006 VERY nice setup. how much did that thing cost? will it work with the Radix heat exchanger in there? Link to comment Share on other sites More sharing options...
detjoe Posted April 16, 2006 Report Share Posted April 16, 2006 I think it may work better flipped around. Nice pics. <{POST_SNAPBACK}> or side ways, too much hose! Link to comment Share on other sites More sharing options...
Bowtie70SS Posted April 16, 2006 Report Share Posted April 16, 2006 The reason to still run it through the radiator is to keep the trans fluid temp from exceeding the coolant temp. Example if your are idling in traffic or the temp spiked for some other reason. I always run both coolers (rad and aux) but run the fluid thru the radiator first, then the aux to cool it down further.BTW your setup looks nice I like the cooler.

dneumannjr Posted April 16, 2006 Author Report Share Posted April 16, 2006 In reply to the cooler being upside down or mounted that way I went with what the instructions told me to do. Because of the termostat they tell you not to mount the cooler with the thermostat pointing straight up. They say that it will not read properly that way. I could have mounted it sideways but the brackets where alrady made up. I will probably change this when I go with the AN fittings and braided lines.I thought about just mounting it up right but it would be nice to have the thermostat function properly. Do you guys think that the thermostat will funtion properly if I switched it around and the thermostat was located at the top? I would prefer to have the hoses at the bottom.

dneumannjr Posted April 16, 2006 Author Report Share Posted April 16, 2006 I got it from Summit's Ebay store for $200 plus $10 to ship. I am not sure if it would work with the Radix cooler thought I am not sure how it mounts. Or what kinda clearance there would be. I think it may work better flipped around. Nice pics. <{POST_SNAPBACK}> Link to comment Share on other sites More sharing options...
dneumannjr Posted April 16, 2006 Author Report Share Posted April 16, 2006 Thanks I like it too! It turned out really nice and the trans temps seem to be much better. Anyone have any idea what size AN fittings I am going to need to replace the stock lines? The reason to still run it through the radiator is to keep the trans fluid temp from exceeding the coolant temp. Example if your are idling in traffic or the temp spiked for some other reason.

Holty Posted April 16, 2006 Report Share Posted April 16, 2006 keep us updated on the AN fittings and such, i'm planning on doing the mine the same way with AN fittings and ss braided lines. Link to comment Share on other sites More sharing options...
dneumannjr Posted April 16, 2006 Author Report Share Posted April 16, 2006 Sorry pics where a little big hey..... They have been resized. I think it may work better flipped around. Nice pics. <{POST_SNAPBACK}> Link to comment Share on other sites More sharing options...
dcairns Posted April 16, 2006 Report Share Posted April 16, 2006 Since I don't have a themostat controled bypass on the cooler line, I left it running through the radiator. I figured it would warm the transmission fluid in cold weather and still provide a bit of cooling in hot weather. I cut and re-arranged the existing tubing to keep from using rubber hoses. The hardest part was coming up with a way to get from the 1/2 inch NPT pipe thread on the cooler to the 3/8 inverted flare fittings. What was B&M thinking when they chose NTP?

wody Posted April 17, 2006 Report Share Posted April 17, 2006 shouldn't the fan be behind the core pulling the air through the fins. if left the way you have it, i would think the temp between your stock cooler and this one aren't going to be any different. instead of pulling "cooler" ambient air through, you are pulling engine heat through the fins, also restricting ambient air from passing through your condensor and radiator.
