This package includes most of the items that could cause a leak from the E46 expansion tank. If you're not sure where your leak is coming from you can give the whole area an overhaul using these parts. Most likely it will be from the expansion tank itself but in some cases it could also be from a damaged seal or connector. We have put this package together with a discount to save you money.

Parts list:
  • OEM expansion tank, #17117573781
  • OEM expansion tank cap, #17117639022
  • OEM upper radiator hose, #17127510952
  • OE BMW installation clamp, #17111707777
  • OEM coolant level sensor, #17137553919
The only items not included are fresh BMW coolant, heater return hose, and the expansion tank mounting plate. The return hose and the mounting plate are rarely the source of leaks on the E46 radiator. On manual transmission cars the mounting plate contains a drain valve but not much else. If there is a leak from a freshly installed expansion tank it's more likely that the tank is not seated all the way on the mounting plate (it should click into place). Buying a new mounting plate will make installation easier because you can assemble everything together off the car where there is more room. Should you want to include the mounting plate or hose you can select them from the options below. If your coolant is more than two years old it should be replaced. You can add some to your order from the options below or pick it up locally and save the shipping cost.

This kit fits cars with manual transmission only.
