Detailed Description

Mahle GS33598 is an engine cylinder head bolt set engineered for secure cylinder head retention during engine assembly or head gasket replacement. Mahle is known for sealing and engine service products used by OEMs and technicians, and this hardware follows an OEM-standard approach for fit and function. This part cross-references FEL-PRO (e.g., ES 72244) for the same application. Use the Mahle GS33598 when servicing 2004-2008 Chevrolet Aveo, 2007-2008 Chevrolet Aveo5, or 2005-2008 Pontiac Wave engines that require torque-to-yield cylinder head bolts.

What It Helps Address

• Loose or uneven cylinder head clamping after engine teardown
• Head gasket service that requires new torque-to-yield bolts
• Fastener stretch or fatigue from prior engine repair
• Improper sealing caused by reused head bolts
• Restoration of correct cylinder head fastening during rebuild work

Installation Notes and Tips

Confirm engine code and bolt specification before installation. Torque-to-yield bolts require the exact tightening sequence and torque-angle procedure specified by the vehicle or engine service manual. Clean threaded holes thoroughly, inspect the cylinder head and block surfaces, and replace any fasteners that show damage or corrosion. For fitment, this part fits 2004-2008 Chevrolet Aveo, 2007-2008 Chevrolet Aveo5, and 2005-2008 Pontiac Wave.
