328 88 leaking coolant

Its the overflow & its because your reservoir cap needs replacing. They don't last, spring gets weak & won't hold operating pressure. Keep a close eye on coolant level until you get it replaced & make sure you get a 1.1 Bar cap.

It also happens if you are simple overfilled. When cold, check the level, it should be 6cm from the the filler neck. If too much, it will spit and spurt the excess out....

 

After going through two factory caps, including the new and improved 1.1 bar, I was still getting overflow. The level is correct, so I just went to Pep Boys and got a cap. Works fine, and the other two are for Concours...
