Over the past couple of days I have noticed a slight antifreeze odor when running the defroster or heater. No leakage on the floor. The reservoir was low but not empty. The last time it was added to was a couple of years ago when the water pump was replaced.( second replacement by dealer)
Is it possible that the pump may be going again and the odor is coming in from under the hood? Has the heater core been an issue? How much can I expect to pay to have the heater core replaced by the local dealer?
Thanks for any info.
