Product Details

The Rein 17-11-1-723-521 is a replacement coolant overflow hose — also commonly referred to as an expansion tank hose — that connects the coolant expansion tank to the radiator. This hose plays a critical role in the cooling system by allowing coolant to flow between the radiator and the expansion tank as the engine heats and cools.

A damaged or deteriorated overflow hose can render the expansion tank unable to function properly, leading to coolant loss and potential engine overheating. Replacing a worn hose with a quality aftermarket unit like this Rein hose restores the integrity of the closed cooling system.

Key Features:

  • Direct-fit replacement for the OEM expansion tank-to-radiator overflow hose
  • Replaces OEM part numbers: 17-11-1-723-521 and 17-11-1-723-700
  • Engineered to OEM specifications for a proper fit and reliable seal
  • Restores proper coolant circulation between the expansion tank and radiator
  • Compatible with 2.8L and 3.0L 6-cylinder applications

This hose is sold as a single unit and is a straightforward replacement for maintaining a healthy BMW cooling system.

so far so good!

Great price on a great product! The Thule Raceway 9002 3-bike trunk-mounted rack is what I purchased. Shipping was fairly quick and the product was new, in original packaging and was a great deal compared with other sites for the same product! Would order again!

OK - would use payapl but didn't see how

inexpensive. good site.

Great price and quality is very good . Easy to install

I purchased an Optima Red Top 75 battery from Autoplicity and they have some of the best prices available. The item was shipped right away and they knew the inventory that was available, not like others who said there may be a 2 to 3 week shipping time frame. So far the service has been great and I look forward to continued great service.

This includes both sides right and left right?

I am extremely happy with Autoplicity from start to finish! They had the best prices online on Hawk Performance pads and were shipped the day I ordered. They were at my door step within two days of me ordering them! You can't beat that anywhere. Cheaper and faster, it truely dosen't get any better than that.

very easy
