Coolant smell inside of car - Ford Forums

cbktheman · 02-16-2008, 17:37

I own a 2004 40th anniversary edition mustang with a 3.9 litre v6.
Recently i started smelling anti freeze coolant inside of the car and also notice that there seems to be coolant accumulating on the window above the dashboard.There is also moisture in the ac/heat vent on the drivers side that smells like coolant.
Does anyone have any ideas as to what the problem may be ?
Any help will be greatly appreciated.

I would have that looked at, sounds like the Heater Core is bad,
the Heater core transfers the hot coolent into the car and blows air accross it to heas the inside of the car. you can by pass it by removing the two small hoses that connect the the firewall and coupling the two ends together
until you can her the core fixed.

I agree, heater core, but I wouldn't bypass it. Get it fixed.

Typically the heater cores are relatively cheap, but on the old Fox bodies the entire dash has to come off. I've never changed one on the SN body styles but since the platforms are the same, the method may be the same. It's not a really HARD job, it just take FOREVER to get all the bolts and screws.

Thats true Alajones is right.Try check Coolant level is normal. Pressure tests.I have a quick search about this problem in ford parts news and told me to replace the overflow cap / which also acts like the radiator cap. The seal could be seaping causing vapors to escape.

I hope it works..

Heater core, pull up your carpet and see what you find

Heater core for sure. Lengthy job, but it goes faster if you share your time with a 24 case! There are kits available that allow you to do a back-flush of the heater core to remove any rust/debris that can accumulate to prevent flow and ultimately failure. They hook up to a standard garden hose and prices do vary. I back-flush my vehicles every 2-3 years depending on mileage. You'd be surprised what can come out of one of those things.
