Fixing Head Bolt Thread Failure in Your GM Vehicle with GEN V Engine

General Motors (GM) has produced several vehicles with a GEN V 5.3L or 6.2L engine, including the Chevrolet Silverado 1500, Tahoe, and Suburban, the GMC Sierra 1500 and Yukon, the Chevrolet Camaro SS, the Chevrolet Corvette Stingray (C7 and C8), and the Cadillac Escalade, CT4-V Blackwing, and CT5-V Blackwing. However, these engines are not without their issues, and a common problem with the aluminum block is head bolt thread failure. The size of the head bolt is M12x1.75. This was changed from M11x2.0 that was used previously. 

Fortunately, there is a solution to this issue. Wise Auto Tools offers the EN42385-50 Time Sert M12x1.75 thread repair kit, which is designed to fix the common problem of head bolt thread failure in the aluminum block. This kit can be used over the fender and makes the threads stronger than the original ones. Time Sert products are made in the USA and the kit is designed to be easy to use, even for those who are not experienced with installing new thread inserts.

If you are working on a GM vehicle with a GEN V 5.3L or 6.2L engine and are experiencing head bolt thread failure in the aluminum block, Wise Auto Tools offers a solution with their EN42385-50 Time Sert thread repair kit. See a list below of the vehicles that this kit is used on.
