Yes, I'm a moron. I stripped one of the three nuts on the thermostat housing on my 2003 LS430. What's the best remedy? Buy a nut extractor? Other ideas?

What are the chances that my local Lexus dealer has a replacement nut for a 2003?

Thanks in advance.

 

Here is another idea, use a nut cracker. I am not sure if you have enough room, so this may not work. https://www.lowes.com/pd/Kobalt-Nut-Cracker/999957787

Local Lexus dealer should have replacement nut, if not, they can order it.
