Don't you know that only inches away from your feet, there is a hot water traveling through the heater core in your passenger compartment? This is not to give you a fright but hey, it's true! That water traveling through the heater core is actually the engine coolant. It is the same stuff that travels through the radiator. The logic behind the invention of the heater core goes like this. Because your engine produces excessive heat that needs to be sent away, vehicle engineers thought of sending it through the heater core to provide warmth to the passenger compartment rather than employing electric or gas-fired heater. Thanks to these cunning engineers, there is something you can depend when it is cold outside!
The heater core is actually like your radiator, although it is smaller. It also helps in times when the radiator overheats. By simply turning the radiator on full blast with the fan simultaneously on high, the engine's temperature will eventually subside. True — the heater core is a secondary cooling system since it has the same behavior similarly to how the cooling system works. So when your Mitsubishi starts to overheat, you know what to do. The heater core is positioned below the dash on the passenger side and is incorporated with the air conditioning system.
As your Mitsubishi vehicle ages, expect that your heater core, just like the radiator will corrode and leak. Usually, the corrosion is the result of insufficient coolant changes. This can be avoided if you change the antifreeze on a regular interval that is basically every two years. Note that corrosion causes the heater core to leak. The corrosion may come either from the acidic coolant eating away at the joints of the heater core or from the regular pressure produced by a blocked heater core that ruins the joints. Interior damage, mold, foul odors and rust are most likely to exist when the heater core starts to leak. More so, there can be a reduction on the amount of heat you need during a cold day as a result of a blocked heater core.
Preventing all of these is the key to keeping your Mitsubishi heater core at its best. Be alert enough when you notice some strange stuff. If your Mitsubishi is losing coolant and you don't know where it came from and your carpet appears to be damp for vague reason, and finally if your car releases lesser heat than normal, check out the heater core.
