Water Pump Gasket 14-22 Hemi 6.4L

The Water Pump Gasket 14-22 Hemi 6.4L is an OEM-specification replacement seal engineered to prevent coolant leakage at the water pump mounting surface on 2014–2022 Dodge Ram trucks and Jeep Wrangler models equipped with the 6.4-liter Hemi V8 engine. This gasket is a wear item that degrades over time due to thermal cycling, pressure cycling, and exposure to coolant additives, making replacement essential during any water pump service or routine coolant system maintenance. For owners pushing extended intervals or experiencing slow coolant loss without visible external leaks, a compromised water pump gasket is often the culprit.

Manufactured by MAHLE ORIGINAL/CLEVITE under OEM standards, this gasket is precision-molded to create a reliable seal between the water pump body and engine block, accommodating the specific bolt pattern and surface geometry of Hemi 6.4L engine architecture. The gasket material is formulated to withstand sustained coolant temperatures in the 190–210°F operating range while resisting erosion from circulating coolant flow and maintaining compression under bolt load. At just 0.12 lbs and compact dimensions of 9.05 x 0.8 x 11.2 inches, it fits the factory mounting locations without modification, ensuring proper pump alignment and eliminating the risk of coolant bypass or air entrapment.

This replacement gasket is ideal for DIY enthusiasts and professional mechanics alike who are servicing the cooling system on fifth-generation Ram 1500 trucks, third-generation Ram 2500/3500 heavy-duty models, or JL/JK Wrangler platforms with 6.4 Hemi power. Installation requires removal of the water pump assembly, cleaning both sealing surfaces with a gasket scraper to remove old material, and careful bolt torque sequencing to avoid uneven compression. Always pair this gasket with a fresh water pump if the original unit has accumulated high mileage, as reusing a worn pump seal when installing a new gasket invites premature coolant loss and potential overheating.
