Why do you smell antifreeze in the cab of your Subaru?

Antifreeze is used to heat the cab of your vehicle. When you turn on your heat in your cab, it opens up a valve that allows the hot antifreeze to flow from the radiator into the heater core. If there is a leak in the rubber tubes that flow into the heater core, or if the heatercore is damaged, you will smell the antifreeze in the cab of the vehicle. You may need new hoses to the heater core and/or a new heater core.

Can anyone tell me why my 95 F150 heat goes hot and cold gage all over the place?

I could be there is not enough coolant in the system, therefore, not totally submerging the temp gauge sensor in hot fluid. check water pump for leaks, heater core, or radiator, smell around for a " sweet" smell under passenger side dash, that's where the hearer core is, and antifreeze has a distinct sweet smell..
