The heater core is cracked. You may also be smelling a sweet sort of smell when you turn on the heat and the car is running hot. That sweet smell comes from the anitfreeze when it burns.
I have a 1998 Ford Expedition and I smell antifreeze inside the truck. also antifreeze leaking around the passenger side of motor outside..... I can see a mist coming out of the ac vents.... could it be bad heater core and is it easy to fix or do you have step by step removal/installation instructions? please help
Your heater core is probably cracked. There is alot of work to get to the core. You have to remove the front dash board.
You probably have a leak in the heater core.
The car will over heat.
heat core. leak. thermostat. no antifreeze.
No. they're dissolved in each other and are quite hard to seperate.
Coolant leak, possible heater core. Suggest to have it pressure tested to find leak.
There may be a hole in the radiator?
maybe your head gasket
The leak would vary on the size of the hole or seal failure.
If not tight enough to seal it will leak.
