Thread size for DeWitt radiator EOC holes
Tom (or anyone) - what is the thread size and pitch for the fittings to the oil cooler in your radiators (specifically A90E).
I have 10 AN hose and ends for my current exteral OC, it looks like you're using NPT threads and I need an adaptor.
Thanks in advance.

Tom, thanks for checking in. Rad looks great, sorry for all the messages on your office machine...I got a little over-anxious.
I decided to run both the internal EOC and my external to keep temps down. I was quickly exceeding 250* on track with the external, I'd like those temps down in the 220 range if possible.
Anyway, do you sell any adaptors from SAE to AN threads? I'm not sure where to get them around here and this needs to be in and running by Friday...
Thanks again.

Look for a local hose and fitting shop that speciallizes in this stuff.
If you can't find anything local you can always call Orme Brothers @ 818-885-1414 / www.ormebrothers.com
I got all my fittings from them when I hooked up my Dewitt Radiator with EOC.
Basically you will have the #8 SAE threaded O-ring fitting into the radiator then another 10AN fitting to it.
The fitting is about $15.

I was able to call around and I found everything at a local speed shop that I didn't know existed. They had to order the SAE to AN adapters but had everything else. It's turning into a mess under there...
Block line to radiator is SAE / AN, then the line from the DW rad to the external cooler is AN / SAE (different size, of course), then back to the block. My oil system is going to be 11 qts...if I ever have temp issues again this car is going to the bottom of a lake.

One more thing - what is the torque spec to the radiator?
The adaptors are steel, I don't want to over tighten them and damage the aluminum thread.
BTW, for those who also might need this info, Summit has all of the fittings, hoses, and adaptors, I just wanted them today so I could finish tonight.

I used the German torque spec of goodentite!
They have an O-ring to seal.
If you have not assembled the hoses yet, I found using a vise to hold one end still while I wiggles on the stainless steel hose to it worked well.
I found this online to help me figure out how to assemble the fittings as I never did it before. Has a variety of different fittings and hoses and how to guides.

Does it have a spot for an o-ring at the base? Where the threads end?
Kind of looks like this, but with the o-ring on the nipple end going into the radiator.
Did my best to search for the correct one, but can't find one. Wish I had an extra one laying around!

Don't pay attention to the 8AN that is really a #8SAE (3/4-16)

Earl's has the 8 SAE and call it 8AN. Aeroquip makes an 8 AN to NPT but no SAE. The local hose and fitting shop sold me an 8AN to 8 SAE but the flange is 37* and the AN flange is 45* so it won't seal.
Cripes. Earl's parts on the way from Summit, looks like my one day job is up to 5 days.
