thank you for your posts -- I have not as of yet gotten a malfunction light -- no codes stored,
it does make a nnnnnn noise when it starts up which has gotten like a zzzzz noise --
my husband thinks some bearing is failing somewhere --- like a coolant pump?
I was told that there was a coolant pump that circulates stored antifreeze into the engine prior to startup -- at another dealer -- is this true? maybe this could be the pump that might be failing?
anyone have any experience with this? --- seems to have gotten worse since the cold weather set in
again, though thanks for your help --
