Product Details

The Mahle Cylinder Head Bolt Kit line is focused on sealing and fastening components used in critical engine service. Mahle is known for gasket and sealing products trusted by OEMs and technicians, and this GS33489 kit follows that service-focused approach with hardware specified for cylinder head fastening. For vehicles such as the Mazda 3, Mazda CX-5, Ford Explorer, and Ford Transit Connect, correct head bolt clamping is essential during cylinder head replacement, gasket service, or engine teardown and rebuild procedures. This part cross-references FEL-PRO ES 72207 for the same application.

Common Repair Uses

• Replacing stretched or torque-to-yield head bolts during cylinder head service
• Restoring proper cylinder head clamping after head gasket replacement
• Addressing coolant loss, compression loss, or combustion sealing concerns tied to head fastener wear
• Supporting engine rebuild work where factory-style fasteners are required
• Servicing engines in Ford Escape, Mazda 6, and Lincoln MKZ applications

Installation Notes

Follow the specified tightening sequence and torque stages exactly: Stage 1 to 5 Nm, Stage 2 to 15 Nm, Stage 3 to 45 Nm, then turn 90 degrees and an additional 90 degrees. Because this is a torque-to-yield fastener, use the correct procedure, clean threads, and the proper T-55 Torx socket cap tool. Verify engine code and vehicle application before installation on Mazda CX-30, Ford Ranger, or other listed fitments. Mahle GS33489 should be installed according to the service manual for the specific engine.

Quality Assurance

Mahle manufactures engine sealing and fastening products to OEM-standard expectations for service and repair use. The GS33489 cylinder head bolt kit is built for confirmed vehicle applications and follows the torque-to-yield requirements specified for the application.
