Does anyone know the size of the head on the harmonic balancer for a 99 frontier?? 2.4l..

It's probably going to be 27MM (1-1/16"). I only recall ever seeing 3 different size crank bolts on Nissans: 27MM, 22MM (7/8") and on the VQ engines, 19MM.

Definitely not a 19 mm .. all I said was feel it with my fingers yesterday and I knew it was in the 20's.. 27mm probably.. I guessed 22 or bigger but I think it's the 27. Thanks man...

Yes, the 19MM is only used on the VQ engines to my knowledge.

Ok, 1-1/16 fit snug.. I have an auto and I see the question all the time how to break loose how to tighten.. I used my starter to break loose, and I vise griped the harmonic balancer and let it rest on something metal... Worked great. It was just loose.. thanks for the replies

I saw somebody try that trick on a VG engine and they ended up breaking the starter housing. If you don't have access to an air impact gun, the best and safest way is probably to use a small tie down strap and run it from the frame, around the balancer a few times and back to the frame. Then use a breaker bar and socket on the bolt.

I suspected mine to be loose anyways bc I know the guy that had it before me do the timing set and he didn't use a torque wrench just bumped it with impact. I should've said there's that risk if you do it that way you're right.. I didn't have access to a strap at the time.. could've used vise grip both ways I believe, it really held.. just make sure the vise grips aren't slipping on the pulley and damaging it. I put out feet on tire with both hands putting out and the vise grips didn't slip.
