Detailed Description

Rein CHT0974 is engineered as a replacement coolant hose for turbocharged BMW models that use an auxiliary water pump to oil filter housing connection. The hose material is selected to withstand the thermal load and fluid exposure found in turbocharger cooling systems, helping maintain consistent coolant routing where original hoses can harden, crack, or deteriorate over time. This part is a practical service replacement for BMW 440i, BMW M240i, and BMW 340i applications, along with additional 5 Series, 7 Series, X3, and X4 fitments listed below.

Rein focuses on OE-style replacement components for cooling and turbo system service. CHT0974 follows that approach with a standard replacement design intended for the specified BMW fitments and the same routing as the original line.
