TIME-SERT® GENERAL MOTORS PROFESSIONAL THREAD REPAIR KITS
NORTHSTAR HEAD BOLT REPAIR KIT
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
