Rein CHK0005P Radiator Coolant Hose Kit - Lower

OE-Style Lower Radiator Hose Kit

Rein CHK0005P is a direct-fit radiator coolant hose kit for European applications that need an OE-quality lower hose replacement. It is built for 1999-2003 BMW 528i, 2001-2003 BMW 525i, and 2001-2003 BMW 530i lower hose service, with the temperature sensor preinstalled to simplify the repair.

Made from EPDM and shaped for application-specific fitment, this Rein radiator hose kit follows the original hose layout without cutting, refitting, or adjusting. The thermoplastic quick-connect style design helps maintain a secure connection at the cooling system interface.

• Preinstalled temperature sensor helps reduce repeat repairs from reusing the old sensor
• Direct replacement for OE hose assemblies
• No cutting, refitting, or adjusting required
• EPDM construction resists heat, salt, road debris, oil, and other contaminants
• Application-specific fitment for European cooling system service

Detailed Product Overview

Rein CHK0005P is a lower radiator coolant hose kit engineered for BMW cooling system repair where OE-style fit and function matter. It is a single hose assembly with a black EPDM body, a centerline length of 18.5 inches, and a maximum working pressure of 50 psi. The hose includes the temperature sensor already installed, which supports a cleaner replacement process on 1999-2003 BMW 528i, 2001-2003 BMW 525i, and 2001-2003 BMW 530i lower hose applications.

This part cross-references Rein CHK0005P for the same application.

Common Repair Uses

• Lower radiator hose leakage
• Cracked or aged EPDM hose material
• Fault codes or drivability issues related to a failing coolant temperature sensor
• Coolant loss from worn quick-connect fittings or seals
• Repeat cooling system repairs caused by reusing old sensor components

Installation Notes

Compatible With 1999 BMW 528i, lower; 2000 BMW 528i, lower; 2001-2003 BMW 525i, lower; and 2001-2003 BMW 530i, lower. Verify hose routing, connector style, and sensor location before installation. Because the temperature sensor is preinstalled, transfer of the old sensor is not required.

Use proper cooling system service procedures, inspect mating surfaces and seals, and confirm the hose is fully seated before refilling the system.
