I looked and did not see anyone having posted about this yet.
So here goes, considering that the newest 3rd Gen T4R is 12/13 years old, there is no doubt that screws are stuck beyond what penetrating chemicals can fix, and will end up with a stripped top. That, or a bolt is likely to have the head snap off.
The other day, when trying to remove my MAF sensor, the screws were badly stripped, and my attempt at removing them with a screwdriver did not help things.
This is the screw extractor set I used, I bought it from Home Depot for $8.95 - ish, and used the #1 extractor for the screws on my MAF sensor screws.
Following the placard behind the extractors, I used a 7/64" drill bit, and drilled in the screw head a little bit.
I went just a little bit further than this.
Then I put the extractor into my drill, and instead of drilling down, I put the drill into reverse (the extractors are left hand threaded), and just went nice and slow putting lots of pressure behind the drill.
Sure enough, a second later the screw started to come out.
And bam, stripped screw removed!
This process would work the exact same for any bolt that had the head snap off. Just drill into the center of the bolt, then with your drill in reverse, and applying pressure, drill into the bolt shaft with the extractor until the bolt starts to back out.
In the event the extractor does not engage the metal, drill a little further with the appropriate size drill bit, and try again.... the first screw took me about 3 attempts until I got deep enough with the drill bit. Just be careful not to over drill when removing small screws because, because you might drill into the material the screw is stuck in.
Good luck! Hope this helps someone!
