Instead of getting a trans cooler (which the last one i had the end broke off after awhile) I'm running my fluid through the AC condenser. I run it through the radiator then into the condenser. Helps warm it up then keeps it cool enough when it gets hot and humid around here. The only problem i'm having is no matter how well i flare the ends and even with two hose clamps it still leaks really bad.

So instead I want to know the size of the threads that come off my AC condenser so i can just get a female thread to NPT.

I tried bending lines and just have it hard lines but the angles are way to compound. Should i maybe use -AN? How would i do that?

 

My initial tought is that the condenser is a too long and thin tube that represents a considerable resistance to the viscous oil, thus giving high pressures and leaks.
I have seen someone recommending connecting different coolers in parallell (using Tees) instead of in series. Thus the flow is less likely to get obstructed for any reason, it gives lower pressures instead of increased, and you still get the same combined cooling capability.

 

But then the fluid will take the path of least resistance. Then it wont go through the condenser.

Still would like to know the size and thread.
