If you smell coolant than it is leaking somewhere. You could be drawing the smell in from the radiator or the hoses going to the heater core. The best way to find the leak is to pressurize the system with a teaster and go looking. Generally if you have a leaky heater core the windows also fog up. If all you are getting is the smell the core may be OK but something else is leaking somewhere! If it comes and goes maybe it's the guy next to you? The best insurance is to just change every hose. Look over the radiator. Look carefuly at the end tanks. If you see any evidence of green staining than it is on borrowed time. No one should be driving their Delorean on the origional hoses! After 23 years it is just asking for trouble.

I understand the basics of how a heating system works and that coolant runs under the passenger dash but what would cause it to smell? My coolant level has not changed and there are no leaks from under the passenger dash. Anyone else smell coolant when their heat is running? Any ideas what I need to do to fix it? I am also wondering if a light smell of coolant is normal with our system. > > thanks > Mike C > 2109 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
