Question about Heating & Cooling
Your mechanic is likely correct. Pretty much any vehicle will eventually develop a clogged heater core, especially if your antifreeze/coolant system has never been "flushed out" to remove lime scale. The antifreeze/coolant flows through the heater core and warms air that passes through it, but your mechanic has something similar to CLR that will dissolve what clogged it. This is usually still referred to as "boiling out" your heater core, but it's been decades since it actually involved boiling the thing to dissolve the lime scale clogging it. The products you can buy today that will "flush out" the engine coolant system are designed to dissolve and remove these clogging bits of crud, though if it's already clogged up it may take some time running the engine to get through to the heater core to clean it out. Most mechanics will simply recommend replacing the heater core, because this is a much faster and much more guaranteed cure to the problem - even though you pay more for it.
