Detailed Description

Nissens 91447 is an engine oil cooler engineered to regulate oil temperature so lubricated components can operate under proper thermal conditions. By helping control heat in the oil circuit, this cooler supports consistent lubrication performance and reduces the risk of heat-related oil breakdown in the specified Hyundai Elantra, Hyundai Ioniq, and Kia Niro applications. The aluminum core and compact donut design match the listed OE-style configuration, and the unit is supplied without housing for vehicles that reuse the original housing assembly. This part cross-references OE numbers 2641003HA0 and CLC377000S for the same application.

Vehicle Fitment

• Fits 2017-2022 Hyundai Ioniq, N/A, WITHOUT HOUSING
• Fits 2017-2022 Kia Niro, N/A, WITHOUT HOUSING

What This Part Helps Address

• High engine oil temperatures
• Oil breakdown from excessive heat
• Reduced lubrication performance in hot-running conditions
• Oil cooler leakage or internal wear at the OE unit
• Replacement needs for a damaged cooler without housing

Installation Notes and Tips

Confirm the vehicle uses the without-housing configuration before ordering. Match the existing cooler style, core dimensions, and OE reference numbers during installation. Inspect the sealing surfaces, oil passages, and surrounding cooling components for contamination or wear before fitting the new cooler. Proper system cleaning and fresh seals, where required by the vehicle service procedure, help support a reliable repair.

Quality Assurance

Nissens oil coolers are built as quality heat exchangers and are backed by in-house testing to verify compliance with internal standards. That testing focus supports consistent fit, thermal performance, and long service life in the listed applications.
