Performance Water Pump Kit for Chrysler 300 (2011-2019) 3.6L

Heavy-Duty Performance Water Pump Kit for 2011-2019 Chrysler 300 (LD)

What it Does: The Performance Water Pump Kit circulates pressurized engine coolant through the block and cylinder heads on the 2011-2019 Chrysler 300 to maintain optimal thermal regulation and eliminate hot spots.

The Stock Chrysler 300 Cooling System Weakness

Factory water pumps on the 3.6L Pentastar V6 are prone to early mechanical seal breakdown and bearing failure, frequently surfacing between 50,000 and 80,000 miles. Sustained thermal cycles degrade the stock unitized shaft seal, permitting coolant weepage past the internal cartridge. Once coolant breaches the bearing assembly, it induces radial shaft runout, pulley wobble, squealing, and rapid coolant loss that exposes the LD aluminum cylinder heads to severe warping from overheating.

The Engineering Solution

Engineered as a rugged, direct-fit replacement, this pump features a precision-cast aluminum housing fitted with an upgraded, heat-resistant carbon/ceramic mechanical shaft seal. A high-efficiency cast impeller resists cavitation across high-RPM loads, maintaining consistent hydraulic line pressure without parasitic drag. Designed to replace OEM references 5184498AE, 5184498AH, 5184498AI, and 5184498AD, it includes an OE-grade elastomer gasket to create an airtight, leak-free seal against the timing cover.

Frequently Asked Questions & Fitment Warnings

Does this fit the LD 300?

Yes, this is a direct fit for the 2011-2019 Chrysler 300 equipped with the 3.6L Pentastar V6 engine. Compatible with 3.6L Pentastar V6 only; does not fit 5.7L or 6.4L HEMI V8 models.

What torque specification should be used on the mounting bolts?

Torque all water pump mounting fasteners in an alternating sequence to vehicle manufacturer specification (106 in-lbs / 12 Nm) to ensure proper gasket compression without warping the housing.
