Trying to replace my thermostat and apparently the bottom screw stripped. What are the options to get it out?

 

Can you post a cellphone picture? That would help us give you the most useful advice.

No car, No motor, No answer.

2003 STR per JagGirl's member profile page.

I don't know if the V-8 practiced the same affront to common sense as the V-6, selling you a new thermostat complete-in-housing when you needed an upper rad hose because the silly little turret broke, but if so, you should be able to find plenty of low-cost or free t-stat housings by just asking....I think I may have two for the 3.0L lying around the shop somewhere.....

 

threads stripped or head rounded off? big difference in issue. And Its a metal cross over pipe on the STR SC V8. but the little 8mm bolt heads do tend to round off which is why I use snap on 6 points on them. others tend to open too much and round a frozen bolt since steel and aluminum really tend to like each other much over time and seize

 

Maybe the car is X200 4.0 and the brass insert in the resin housing is SPINNING?????????????????????
