Hose - Lower Radiator, LATE (OEM) for B6-B7 S4

SKU: OEM-8E0121055AD
This is a brand new, OEM Lower Radiator Hose for your B6-B7 S4. This is the main hose on the driver's side of the car that connects to the bottom of the radiator and to the water pump.

NOTE ON FITMENT: For B6-S4s, there were two different versions of this lower radiator hose. On EARLY versions of this hose, the small 90 degree rubber hose that comes off the T connection and goes to the check valve before the hose that attaches to the the driver side auxiliary radiator will have a uniform size and have an outlet of 20mm where it connects to the check valve. The LATE versions of this hose will have a small 90 degree hose that has a "step-up" in it that goes from smaller at the T connection to a larger diameter of 25mm at the check valve connection.

This is the LATE hose with the 25mm check valve connection.

Most B6-S4s with VINs greater than or after 8E-5-023001 will have THIS HOSE. Most cars with a VIN less than or up to 8E-5-023000 will have a different version of this part (which we also sell). Audi does not list this split as being definitive so it's possible that you may have a hose different than the one identified by your VIN. The best thing to do is to look at the part number from the hose on your car. If you have a hose on your car with a part number of 8E0121055AD (or sometimes 8E0 121 055 AD) you have a LATE hose. Add this hose to your cart and proceed to checkout. If you have a hose on your car with a part number of 8E0121055L (or 8E0 121 055 L) you have an EARLY hose. Go back one section, select that hose, ad it to your cart, and proceed to checkout.

Don't forget to add coolant to your order!
