Product Details

Mahle Cylinder Head Bolt Kit GS33755 is engineered for engine rebuild and head gasket service where accurate clamping load matters. The fasteners use a female star T-55 drive and follow a multi-stage torque procedure: 7 Nm, then 15 Nm, then 55 Nm, followed by two 90-degree turns. This torque-to-yield design is used on modern Ford and Lincoln engines to help maintain consistent cylinder head sealing after assembly. Mahle’s gasket and sealing products are trusted by OEMs and technicians worldwide, and this hardware follows that same OE-focused approach.

Common Repair Uses

• Replacing stretched or removed cylinder head bolts during head gasket service
• Restoring proper cylinder head clamping after overheating repairs
• Addressing combustion sealing issues caused by worn fasteners
• Supporting engine rebuilds on Ford Fusion, Mustang, Escape, and related models
• Correcting torque retention concerns after cylinder head removal

Installation Notes

Follow the factory tightening sequence and torque stages exactly as specified for GS33755. Because this is a torque-to-yield fastener set, use the bolts only as directed by the service procedure and verify the cylinder head and block surfaces are clean, flat, and free of debris before assembly. Confirm engine code and application details for your Ford or Lincoln vehicle before installation, especially on 2012-2023 service applications.

Quality Assurance

Mahle manufactures sealing and engine hardware products to OE-standard expectations, with a focus on accurate fit and dependable sealing performance. GS33755 is built for the demands of cylinder head service on Ford and Lincoln applications where proper fastener load is critical.
