Rein CHE0152 Engine Coolant Hose - Expansion Tank (Lower) To Hose At Heater

OE-Style Coolant Hose for BMW Cooling Systems

Rein CHE0152 is an OE-quality engine coolant hose built for European cooling system service, with application-specific dimensions and thermoplastic quick-connect fittings. It is made for direct replacement use on select BMW 528i, 525i, and 530i models, helping restore proper coolant routing at the expansion tank and heater hose connection.

Compatible With 1999-2003 BMW 528i, 2001-2003 BMW 525i, and 2001-2003 BMW 530i applications at the expansion tank lower to heater hose position.

Key Features

• Direct replacement coolant hose for OE-style fit and routing
• Application-specific design reduces installation time
• No cutting, refitting, or hose adjustment required
• Thermoplastic quick-connect fittings help prevent leaks from reused connectors and O-rings
• EPDM hose construction resists heat, salt, road debris, oil, and other contaminants
• Black finish with single-hose construction for the specified BMW cooling system location

Detailed Description

Rein CHE0152 is engineered as a direct replacement for the original coolant hose assembly used on select BMW E39 and E46-era vehicles. The hose follows the OE branch shape and connector style, including thermoplastic quick-connect ends, so the replacement matches the factory layout rather than requiring modification. This makes it a practical choice for BMW 528i, BMW 525i, and BMW 530i cooling system repair where the hose runs from the expansion tank lower connection to the heater hose.

This part cross-references Genuine 11531438632 for the same application. The Rein CHE0152 part number is also commonly used when replacing the original hose assembly on these BMW models.

What It Helps Fix

• Coolant leaks at aged hose connections
• Cracked or hardened EPDM hose material
• Broken or worn quick-connect fittings
• Coolant seepage caused by reused O-rings or connectors
• Cooling system service delays from hose modification or trimming

Installation Notes and Tips

Verify the vehicle year, model, and hose routing before installation. This hose is specified for the expansion tank lower to heater hose position and uses quick-connect fittings, so the existing connection points should be inspected for wear, corrosion, or damage before assembly. Because the hose is application-specific, no cutting or refitting should be needed when installed on the listed BMW applications.

Quality Assurance

Rein Automotive supplies OE-quality replacement hoses for European vehicles, with construction and connector design based on the original factory configuration. CHE0152 is backed by a 24-month or 24,000-mile warranty.
