TEMSONE Exhaust Manifold Bolt Repair Kit for GM 4.8L/5.3L/6.0L/6.2L — Driver Front & Passenger Rear, Corrosion-Resistant Hardware

This repair kit provides a straightforward, durable solution when exhaust manifold bolts snap or rust away on GM trucks and SUVs. Designed to meet original equipment fitment, the kit stops exhaust leaks at the flange without the expense and labor of removing the cylinder head or drilling out seized studs. Parts are made from corrosion-resistant materials to withstand heat and road conditions while restoring a tight seal between manifold and cylinder head.

How does this kit stop exhaust leaks?

The TEMSONE kit supplies replacement repair bolts and hardware sized to press into the pre-existing broken bolt holes, re-establishing clamping force at the manifold-to-head flange. Once installed, the bolts compress the manifold gasket and prevent leakage of exhaust gases that cause noise, smell, and reduced efficiency.

• Includes repair bolts sized for driver front and passenger rear locations.
• Corrosion-resistant surfaces maintain clamp force under heat cycling.
• Restores proper sealing without replacing manifold or head.
• Compatible with stock manifold gaskets and OE flange dimensions.

Will I need to remove the cylinder head or drill out broken studs?

No — the kit is made for in-place repair so you do not have to remove the cylinder head or perform time-consuming stud extraction. Installation fits into the broken bolt positions and uses accessible fasteners to resecure the manifold.

• Installable from the engine bay using hand tools and a wrench.
• No specialized drilling equipment required for most broken bolt cases.
• Saves labor time compared with head removal or stud re-tapping.

Which GM engines and model years are compatible?

This TEMSONE kit is compatible with GM Vortec and LS-series engines installed in trucks and SUVs from 1999 onward: 4.8L, 5.3L, and 6.2L models (1999–2013 for 6.2L), plus 6.0L applications through 2021. Verify fitment against your vehicle’s engine code and manifold layout before purchase.

• 4.8L and 5.3L GM engines from 1999 and newer.
• 6.2L coverage listed for 1999–2013 models.
• 6.0L coverage listed for 1999–2021 models.
• Driver front and passenger rear manifold bolt positions addressed.

How simple is installation for a DIYer?

Installation is designed to be user-friendly for mechanically inclined DIYers with basic hand tools. Place the repair bolts into the appropriate positions and tighten using a wrench; no head removal or stud drilling is normally required. Follow torque guidance from your service manual and confirm gasket condition while reassembling.

• Simple wrench-tightening procedure — no special tools typically needed.
• Quick replacement that reduces shop labor costs.
• Check and reuse original manifold gasket for best sealing results.

Who is this for? This TEMSONE repair kit suits owners and technicians working on GM trucks and SUVs with snapped or rusted exhaust manifold bolts at the driver front or passenger rear locations. It’s ideal when you want a cost-effective, time-saving repair that restores flange clamping without major engine disassembly. If you own a 4.8L, 5.3L, 6.0L or 6.2L GM vehicle from the listed years and are dealing with exhaust leakage or missing bolts, this kit provides compatible, corrosion-resistant hardware and a 12-month warranty with lifetime customer support.
