How hard is it to fix a broken engine bolt on a mini van?

Which one out of hundreds?

Gotta drill it out install a heli-coil its ez if you know what your doing its a nightmare if you don't approx. 50.00 at a shop

Based on your excellent description, it could be any of the hundreds of bolts on the engine on a mini van. Fortunately, the procedure is the same:
Drill out the center of the bolt, gently run a bolt extractor into the hole until it starts to grab and turn left.
The problem is WHICH of the hundreds of engine bolts needs this procedure… Is it a small one happily sitting on top of the engine? This one should take a 1/2 hour or so if you have SOME mechanical ability. Is it on the bottom of the engine right up against the frame where there's no access? The engine might have to be rocked over after removing an engine mount or even completely removed. I wouldn't wish THAT one on somebody I despised.
Had you provided a better description, you'd have received better answers.How hard is it to fix a broken engine bolt on a mini van - 1
