Thanks for the tips - I'll get back to work

This is the nut I would start loosening.

Just ran across this thread... I know its old but I am in the process of installing a transmission cooler. Did you get that nut loosened? Ive tried PB blaster for days on mine and can't get it to budge... any suggestions?

Continue to soak it, and perhaps gently warm it (quickly and only a little bit, so you don't transfer heat to the rubber line). You could use an oxy/acet. torch for this, or perhaps propane. The heat will expand the nut and help the PB Blaster get in the threads. When you try to loosen it, use a metric line wrench on the hex fitting (not an open-end) and a tightly-adjusted Crescent (adjustable) wrench on the 45 degree angle fitting. That area is fragile, so go slowly/carefully.

Thanks for the reply! I will try some heat later today. And yes the area is fragile. I started to bend the radiator outlet connection to the 45 angle fitting.

You really need to counter torque the square body of the other fitting with a crescent wrench as mentioned above.
