Review on πŸ‘Œ URO Parts 17111712669 Expansion Tank Cap: Superior Quality and Perfect Fit! by Joshua Pilla

Revainrating 1 out of 5

NOT suitable for upgraded Z4 with 3.0 liter N52 engine with manual transmission.

Revain listed this as fitting my car and it was the wrong part number. Lots of coolant splatter from the expansion tank when used on a BMW coolant expansion tank. Part #17-11-7-573-751 has the wrong depth of about 0.75mm and will never seal properly. This is a good quality item so I gave it 4 stars and kept it to myself; I removed the new o-rings from this new cap and put them on my old cap and all the leaks stopped. My car is a Z4 3.0si with manual transmission and N52 engine (E85 model). 17-11-7-639-022 is the correct part number for the N52 3.0 engine with manual transmission.
