Rein EPT0198 Engine Coolant Reservoir

OE-Quality Expansion Tank for Jaguar Cooling Systems

Rein EPT0198 is an OE-quality engine coolant reservoir built for Jaguar cooling system service. It is designed for direct fitment on select 2010-2015 Jaguar XF, 2010-2015 Jaguar XFR, and 2013-2015 Jaguar XFR-S applications, with materials and tolerances made to match the original tank.

This expansion tank uses virgin plastic with no regrind to improve durability through repeated heat cycles and reduce the risk of cracking that can lead to coolant loss. It also includes the sensor that comes with the tank, making it a practical replacement for worn or damaged OE units.

Key Features

• Produced from virgin plastic meeting or exceeding OE specifications for long service life
• Resists cracking and wear from heat cycles to help prevent coolant loss
• Direct fitment supports straightforward installation
• Manufactured to strict engineering standards for materials and tolerances
• Includes the sensor supplied with the tank
• Rein EPT0198 OE-quality replacement for Jaguar cooling system repair

Detailed Description

Rein EPT0198 is an engine coolant reservoir engineered for Jaguar XF, Jaguar XFR, and Jaguar XFR-S models that need a replacement expansion tank with OE-style fit and function. The tank is produced from virgin plastic rather than regrind material, which helps maintain structural integrity under repeated thermal cycling. For vehicles that rely on a stable coolant recovery system, this design supports consistent operation and reduces the chance of leaks caused by cracked plastic. This part cross-references Genuine C2Z29118 for the same application.

Common Problems This Part Helps Address

• Coolant loss from a cracked or brittle reservoir
• Warning lights or sensor-related reservoir issues
• Visible plastic deterioration from heat cycling
• Leaks at the expansion tank body
• Cooling system service needs on Jaguar XF, XFR, and XFR-S models

Installation Notes and Tips

Before installation, verify the part number and compare the original reservoir shape, sensor location, and hose connections to the removed unit. Inspect nearby hoses, clamps, and mounting points for wear before transferring the replacement tank into service. After installation, refill and bleed the cooling system according to Jaguar service procedures to help remove trapped air.

Quality Assurance

Rein manufactures this expansion tank to OE-quality standards using virgin plastic and controlled material tolerances for durability and fit. Rein EPT0198 includes a 24-month or 24,000-mile warranty.
