Slow coolant leak
Hello all,
I have been receiving a low coolant warning on my 2012 E92 on and off. It is probably three to five weeks between warnings. Could it be the expansion tank? That was replaced about two years ago for a similar issue where it split. In that case I was low on coolant every few days. Any tips to check for leaks without a pressure tester? |
