Another question about torquing heads

[trikerbob]

Ok, now I know what they should be torqued at.

 

Has anyone routinely used an impact wrench to tighten the head bolts? Good idea or bad idea and why?

 

I was thinking I'd run over to Harbor Freight and pick up an electric Impact wrench and use that. Could be usefull in a number of other jobs as well, but didn't know if useing one on the heads was a good idea.

 

Thanks, Bob:confused:

NO

 

NEVER EVER use an impact wrench on head bolts, or any engine bolt for that matter.

 

There is a specific pattern that must be done for head bolts, and torque steps. Using a impact wrench on a head bolts is like playing the piano with a sledge hammer. Too much force is applied too fast, and you can not feel the bolt as it tightens. The only two bolts that you could use an impact wrnech on an engine is to remove the crank pulley, or remove the flywheel.

 

Anything else you can get yourself in serious trouble.

Ok, if I understand you correctly, this is probably not a good idea...LOL I got the message, thank you. I just thought I could still do the same 3 step process and set the wrench to each specific torque setting. But I'll stick to the good ol hand held torque wrench.

 

Thanks, saves me a trip to Harbor Freight today. I'll still get one for other uses, and yes, other bolts.
