Show original supplier description
Manufactured by Rein Automotive, an original equipment supplier to BMW, this hose meets all original design, fitment, and performance standards, and is TUV approved. It is presented as an OEM alternative, offering a quality equivalent to Original BMW parts without the premium price tag. This hose is listed by BMW as part number 11531718982 and is intended for the M20 engine. It is specifically designed for 1988 and later E30 325i, 325is, 325iX models, as well as the 1988 “Super E” 325e, and E34 525i models with the M20 engine. It can also be used to convert a 1987 cooling system to the late 1988 E30 system, though this conversion requires additional components such as the radiator, expansion tank, and other hoses. This coolant hose is built to withstand engine heat and ozone exposure, ensuring durability and reliable performance. The brand's commitment to quality is further underscored by a two-year warranty provided with this part.
