see replies in green, A-A-Ron!^^^ they actually have a terrible finish. They didn't polish before anodize... so it's rough. Chinee junk. 3/10.
So question for everyone regarding the trans cooling. I personally hate auto trans... so, never had to deal with this and I have NO clue how much cooling I need... or how to plumb. Are you going to run teh trans through a heat exchanger through the radiator at all? that will dictate how much secondary cooling or main cooling you need
I was looking on Kartek. The Derale's are pretty ugly. So, kinda leaning towards CBR at the moment.
So, what size should I go with? The 9" fans seem like they would barely fit between trunk area and cell if i put them at an angle.. the 5" ones would fit for sure... but i feel like those little guys must be for smaller vehicles. The larger, the better. id go 9"
Should I do single pass or dual pass? Single is fine if you are using a rad heat exchanger. Dual pass wont hurt
Do I need 2x coolers? If I do 2x... i noticed they have 2x in a self contained unit. Or, should I do 2x separate ones? Depends on first question at top
Also, I have read conflicting info on the plumbing when running 2x singles. Some people online have said running in parallel works better. Where you would need a Y-fitting before and after (to split and rejoin fluid to main feed and return.) Is that true? Too may variables to say one is better than the other on other guys trucks. i higherly doubt one will be better than the other with a quality cooler and fan on them
I would honestly prefer 1x line to feed and return if possible...which would put them in series.
As for fitting size. I notice they all seem to be -10 ORB at cooler. I noticed the fittings coming out of trans all seem to be -6. But, I thought I recall barge or someone saying to use -08 on trans lines. bump up to -8 out of the trans and run it to the cooler. make sure the coolers inside dont neck down after the fittings. Derale's do this
Is -06 suitable for the whole run?
Do you plumb the line so the fluid goes up hill? ie feed into bottom and return out top? yes, you dont want an area air can be trapped
How the fuck do you know how much fluid you need? And what stops it from backfilling into the trans and spilling out. put an extra quart in the trans compared to what it calls for and then as it idles, add fluid till you are on the cold marks of the dip stick. nothing spectacular. sometimes the cooler mfg states how much more oil they hold as well. As far as drain back, thats common. Specially from the converter with worn sealing rings. as long as your seals at the dip stick and input/output shafts and other external seals are healthy, its a non issue.
Wow... even more questions than i thought at first! haha
