Removing Oil Lines from Brass Oil Cooler
So I have the 'Limited Edition' Brass oil cooler on my 84 and with Brass being so soft I wanted some advice on the best way to remove these lines.
I was going to heat the nuts but I believe Brass expands more than steel which my be counter productive but please let me know I if I am wrong. Thanks

I'd take a wire brush and start with cleaning off the grime. Then you should be able to have a better change at turning them loose.
Are you wanting to save these.... I had to use a Dremel tool to slice into the connections nuts just enough to put a flathead screwdriver and pry it apart enough for it to turn loose on the threads. Unfortunately I went a little to close to one of the threads and took some of the thread off. (fortunately the nut still turns and tightens back on it)

I have been applying Break Free to the nuts and cleaning them. I forgot to mention, I did use a Dremel on the nuts at the Thermostat and boogered up the threads on one connection so my buddy told me a trick. I removed one of the nuts from the other lines that did not need to be cut and then used a hacksaw blade and cut two lines into the nut, basically making an sst, and 're-threaded' it and now the threads are almost like new. Almost thought I had to buy a new thermostat.....

clean for sure
I used hot wax for stubborn strut bolts on a bmw. I tried everything else before hand but the wax seemed to work.
get the flat tools at harbor freight so you can hold the cooler nut and turn the fitting.

I used Blaster penetrant for 2 days with rags wrapped around the lines and with heat and still lost the battle.
I replaced the lines and cooler because of corrosion-I wish you Good Luck!

I put the wrench's in 3' length's of pipe to act as a cheater and the the 2 nuts that connect the cooler soft lines to the hard lines broke free. But not so lucky with the two rear lines coming off the thermostat, those needed the Dremel and that little guy sliced through the nuts perfectly. One thread on the thermostat got a little 'scratch' from the Dremel while the other line got messed up from the Dremel, it was so bad that I could only thread the nut on about 1-1/2 turns. My buddy told me to take one of the good nuts that I removed and make my own thread repair for the thermostat and it worked! I was almost going to buy the thermostat thread repair 'nut' from our host but this worked and since the seal is not at the threads it should be good to go, the nut now torques on Anyway, posting this here to help anyone out there if they have the same problem I ran into.
