T-stat threads stripped

[scoll911]

In the process of removing the oil lines from the t-stat the threads came with it. I have installed the thread savers on the t-stat (while I look for a good used one).

Question -- the threads are also stripped on the fittings. How do I go about fixing them? Is there a way to fix the threads? Do I need to cut the fittings off and replace? If so, how do you get the new fittings on?

Thanks

by fittings, i assume you mean the nuts on the oil lines. replacing the lines is the easiest way, but i remember a post where someone used an acid that ate the aluminum away. usually the nut threads are ok, they're just full of aluminum.

Thanks for the info -- I found the old thread, used the acid and it worked like a charm. Now, I just need to figure out where I can take the dirty acid.

Dilute it with lots of water and it's safe. No worse than vinegar. You wash vinegar and oil salad dressing down the drain right?
