The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

2013 chevy malibu heater core was leaking and vapors were coming in thru the ac vents. A really sweet smell. Heater core had a small leak, the coolant was leaking a little and would evaporate into the ac vents. I had extended warranty, I purchased. The total cost would have been around $800.00. Seems to be a common issue with Chevy!

I have had the radiator, the head, and now onto a water pump replacement. All due to coolant leaking from the water pump. Hoping this doesn't damage the engine timing belt.

Went to a mechanic and told me that it was my timing Cover gasket. $700.00
