TIME-SERT® GENERAL MOTORS PROFESSIONAL THREAD REPAIR KITS

NORTHSTAR HEAD BOLT REPAIR KIT

NorthStar01

TIME-SERT® KITS HAVE BEEN TESTED AND APPROVED BY GENERAL MOTORS.
There is no other company approved for these repairs in aluminum blocks.

USE A “BIG-SERT OVERSIZED” IF THE BLOCK WAS PREVIOUSLY HELICOILED

NOTE: A good thread repair practice is to always verify the hole depths before drilling.
We recommend a Tap Wrench for tapping and driver tools.

If you need new head bolts or torque specifications contact the experts at ARP (800) 826-3045
