Mahle 55374 Engine Cylinder Head Gasket

Engine Cylinder Head Gasket Overview

Mahle 55374 is an engine cylinder head gasket for select Hyundai and Kia applications. It is built for direct sealing performance where the cylinder head and engine block must maintain compression and fluid separation.

This part cross-references Hyundai and Kia OE numbers 22311-2B600 and 22311-2B601 for the same application.

Key Features

• Multi-layered steel construction for consistent sealing under engine heat and pressure.
• Application-specific fitment for select Hyundai Sonata, Veloster, and Kia Forte, Forte5, and Optima models.
• Mahle sealing products are trusted by OEMs and technicians worldwide.
• Part number 55374 for fast identification and ordering.

Detailed Description

Mahle 55374 is an engine cylinder head gasket engineered for select Hyundai and Kia engines that require a multi-layered steel sealing solution. The fitment data shows coverage for 2013-2016 Hyundai and Kia models, including Hyundai Sonata and Veloster, plus Kia Forte Koup, Forte5, and Optima. For these applications, the notes specify cylinder head bolt replacement or replacement of cylinder head bolts for proper installation, so the fasteners should be addressed during service. Mahle 55374 is a practical choice when restoring head sealing integrity on these vehicles.

What It Helps Address

• Compression loss from a failed cylinder head seal.
• Coolant or oil leakage at the head-to-block interface.
• Combustion sealing issues after engine teardown.
• Service repeat failures when cylinder head bolts are not replaced as specified.

Installation Notes

Verify engine code and production date before ordering, since the listed fitment includes date cutoffs such as to 4/27/2015, 10/05/2016, and 10/07/2016. Follow the fitment notes closely and replace cylinder head bolts where required for correct installation. Confirm all mating surfaces are clean and flat before assembly.
