Snapped a bolt!
Okay I did a bone head move and snapped a bolt while upgrading the plastic coolant jacket to metal. I'm now preparing myself with the arduous task of having to basically remove the front components to give me more space drill and tap the bolt out. Does anyone have any tips on the most efficient way to proceed?[IMG]undefined[/IMG]

Just did this job last night! Well, the coolant flange job. Plastic was disintegrated and leaking. I was definitely thinking "ok don't overtighten" to myself.
You might be able to get a right angle drill in there taking nothing more than the fan out. Good luck! Broke an aluminum bolt doing the oil cooler side of the OFHG. Turned out the bolt was bottoming out, that's why it broke before it was even snug. Learned my lessen. |

Doing the Mickey Mouse mod? I did the same on my E46 while doing the OFHG (longest bolt) and tried to extract it but was unsuccessful. Luckily, it did not leak and I traded it in without a problem.

Had to drill out the 6M bolt drill with a 7m drill bit, to get a clean thread, rethreaded with an 8m bolt.[IMG]undefined[/IMG]

I suggest you use a helicoil to reduce it from 8mm to original 6mm because if this happens again you will have lot bigger hole and bigger issue.

Yup. Unless you have E-torx box wrenches, just like risking a stripped bolt, or don't torque things to spec then you will need to remove the mickey mouse.

Sorry to bring out an old thread, did you remove all the plastic and radiators in the end? Because I´m facing the same problem right now, it felt hard at first and I was almost there, but then it snapped.... |

Yes if I recall I had to remove the fan shrowd in order to have enough space to get a drill bit in there. Not difficult just need to take your time and go slow and go straight. I suggest getting new and hardened drill bits. And a good tapping kit. The aluminum is very soft so you just want to take your time.
