CRP CHE0706 Upper Radiator Hose to Expansion Tank

The CRP CHE0706 is an OE-quality engine coolant hose designed specifically for European vehicles. This upper radiator hose connects the radiator to the expansion tank (coolant recovery tank), playing a critical role in maintaining proper engine cooling system function.

Key Features:

• Direct replacement for BMW OEM part numbers 17128570061 and 17128507235
• Manufactured by Rein Automotive, CRP's premium line of OE-quality replacement parts
• Custom-sized for exact radiator and expansion tank connection
• Constructed from premium materials to withstand extreme temperatures and pressures
• Includes thermoplastic quick connect fittings for secure, leak-free installation
• ISO 9001:2015 quality management system certified
• Made in Turkey to OEM specifications

Function:

This expansion tank hose removes excess pressure from the engine cooling system by allowing heated coolant to expand into the recovery tank. As the engine cools and coolant contracts, the hose allows coolant to flow back into the radiator as needed. Without a properly functioning hose, your vehicle runs the risk of overheating due to insufficient coolant circulation.

Quality Construction:

Rein Automotive coolant hoses are engineered to be identical to OEM specifications, from the size and shape of their branches to the thermoplastic quick connect fittings. Founded in 2007, CRP Automotive introduced the Rein line specifically for European vehicle applications, and all parts are backed by ISO 9001:2015 certification standards.

Maintenance Note:

Coolant hoses should be inspected for leaks, cracks, swelling, and corrosion at connections during every service interval. Replacing worn or deteriorated hoses prevents small coolant leaks from becoming major failures that can leave you stranded.
