Detailed Description

Rein Automotive CHE0638 is a replacement engine coolant hose built for European vehicles that use a thermostat housing to engine layout. It follows the original hose design closely, including the branch geometry and quick connect interface, so it installs like the OE part rather than a universal hose. This makes it a practical choice for Jaguar F-Pace, F-Type, XF, XE, and XJ applications, as well as Land Rover Defender, Discovery, Range Rover, Range Rover Sport, Range Rover Velar, and LR4 models.

This Rein coolant hose is constructed from EPDM and finished in black with silver fittings. The OE-style design supports a cleaner repair by matching the factory routing and connection style, which helps reduce the chance of leaks from reused connectors or worn seals. Part number CHE0638 is also referenced in interchange listings for related OE applications.

Common Problems This Part Helps Solve

• Coolant leaks at the thermostat housing to engine hose connection
• Cracked, swollen, or heat-aged original coolant hose material
• Fitment issues caused by universal hose substitutions
• Repeat repairs from reused quick connectors or O-rings
• Installation delays from hoses that require cutting or reshaping

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and notes before installation. This hose is listed for applications with plastic fittings on several Jaguar models, including specific VIN breakpoints on certain years, so confirm the exact configuration before ordering. Inspect mating surfaces, quick connectors, and seals for wear or contamination before assembly. CHE0638 is a single hose assembly with application-specific fitment, so it should be matched to the exact OE routing shown for the vehicle.

Quality Assurance

Rein positions this hose as an OE quality replacement for European vehicles, with factory-style dimensions and connector design. Part number CHE0638 is backed by a 24-month or 24,000-mile warranty.
