So I decided to save some money and install a new thermostat myself rather than letting the stealership get their hands on it. Everything went well until I tightened the last bolt then snap. The weird thing is that I hadn't even started to really tighten it. Anyway, I tried to drill it out to no avail. I'm not a G35/vehicle expert by any stretch of the imagination so I'd figure I'd ask you guys. Any advice? If I should replace what the thermostat connects to? Any help would be great!

Thanks!

Here is an answer I got. What do you guys think?

 

There are several ways to approach a problem like this. Basically, a good, competent mechanic can use a variety of ways to fix it. That being said, you may or may not encounter such a person at a dealership; instead you may encounter folks who'd just as soon swap out big parts (easier) and let you foot the bill (more $$).

If there is good access around the area, you can drill into the broken bolt with a left-handed drill bit and possibly back it out during the process. If it doesn't back out, then you can use the smaller hole that was just drilled to employ a bolt removal tap (there are numerous kinds), Heat can be used as necessary to enhance the removal as well. Alternatively, in some cases the bolt can be drilled out with a slightly oversized bit and the hole can be re-threaded with larger tap, requiring the use a slightly larger bolt forevermore.

There are lots of solutions, but without seeing it and without knowing your level of competence at such efforts (no offense intended), there is no way to make a perfect recommendation for you. One thing to consider though: in instances such as these, a failed repair attempt can often times cause more harm than good, so if you are not up to the task, it may be best left for a pro.
