torque crank bolt

[freshley]

Can someone give me an idea on how to check that I have the proper torque on the crank bolt? I have a torque wrench but it only goes to 150ft lbs. I have my impact gun and that says it goes to 650 ft lbs. I don't want to strip the bolt or have the bolt come out while I'm driving some day, but the 251 ft lbs you are to have is a lot and I don't know how you'd check it.

it is very very important that bolt is tq correctly a dab of red thread lock and tq it to 210ft lbs is plenty dont use your impact gun
