Engine Oil Cooler Gasket Set 3.6L Pentastar

The MAHLE ORIGINAL Engine Oil Cooler Gasket Set for 3.6L Pentastar engines is a critical OEM-equivalent sealing component designed to prevent oil leakage at the cooler-to-block interface. This gasket set maintains proper compression between the oil cooler housing and engine block, preventing costly external oil seepage that can lead to low oil pressure warnings and engine damage if left unaddressed.

MAHLE ORIGINAL and CLEVITE are OEM suppliers for major automotive manufacturers, and this GS33683 gasket set meets factory specifications for Pentastar 3.6-liter engines found in Chrysler, Dodge, and Jeep applications. The compact dimensions (4.9 x 0.65 x 6.9 inches) reflect the tight packaging of modern engine bay designs, while the minimal weight ensures no impact on vehicle performance. Proper gasket sealing is essential because oil cooler leaks develop gradually—initial seepage may go unnoticed until oil level drops significantly, compromising engine protection during highway driving or towing.

This gasket set is for DIY technicians and professional shops replacing a failed cooler unit or performing preventive maintenance during cooler service intervals. Symptoms of cooler gasket failure include visible oil droplets under the engine, low oil pressure lights on the dashboard, or dark oil stains around the cooler housing. Using OEM-grade gaskets instead of cheaper alternatives ensures lasting compression and reduces the risk of repeat failures within 6–12 months, protecting both the engine and your repair investment.

The Pentastar 3.6L engine is widely used across Chrysler Group vehicles spanning the 2009–2021 model years. Proper cooler sealing directly impacts oil circulation efficiency and thermal stability—essential for vehicles operating in high-temperature climates or under sustained load. This MAHLE gasket set pairs directly with OEM cooler units (part GS33683) and should be installed whenever cooler service is performed.
