Nissens develops thermal components to strict quality standards, and part number 90946 follows that approach for aftermarket replacement needs.

Key Features

• Aluminum construction for effective heat dissipation and corrosion resistance
• Compact core dimensions: 3.8200 in. height, 1.6900 in. width, and 5.51 in. length
• Single O-ring sealing interface for controlled oil circuit sealing
• Direct replacement engine oil cooler for select Jaguar and Land Rover applications
• Cross-reference part numbers include 1682214 and LR025515 for the same application

Detailed Description

Nissens 90946 is an engine oil cooler designed to manage oil temperature in vehicles where thermal stability is critical to engine efficiency and long-term component protection. The aluminum core helps transfer heat away from the oil stream, supporting consistent lubrication performance under load and in stop-and-go driving. This part number 90946 is listed for 2017 Jaguar XE without housing, 2015-2017 Land Rover Discovery Sport, 2014-2017 Land Rover Range Rover Evoque, 2014-2015 Jaguar XF, and 2014-2015 Land Rover LR2.

Compatible fitment language for search includes engine oil cooler for 2017 Jaguar XE without housing, engine oil cooler for 2015-2017 Land Rover Discovery Sport, and engine oil cooler for 2014-2017 Land Rover Range Rover Evoque. Nissens 90946 also cross-references OE-style numbers such as 1682214 and LR025515.

What It Helps Address

• Excessive engine oil temperature
• Reduced oil viscosity from heat buildup
• Thermal stress on lubrication-related engine components
• Oil cooling system leakage at the sealing interface
• Replacement needs for worn or damaged factory oil coolers

Installation Notes and Tips

Verify the vehicle’s OE part number and housing configuration before installation, especially for the 2017 Jaguar XE application noted as without housing. Inspect the oil circuit, sealing surfaces, and O-ring seat for contamination or damage before fitting the cooler. Clean mating surfaces thoroughly and confirm proper alignment during assembly to help prevent leaks.

Quality Assurance

Nissens positions its thermal-management components around controlled manufacturing standards and ongoing product development for the aftermarket. Part number 90946 is part of that catalog of engine efficiency and cooling components, built for service use on the listed Jaguar and Land Rover applications.
