NO HEAT!

[Insidious Surmiser]

It prevents hot water from flowing into the heater core when you are trying to use AC. Think of it as an AC booster.

i'm getting an idea it may be used to also prolong the life of the heater core, in other words, slow down the build up of minerals, ect. just an idea though

From what I understand, it is better to have coolant flowing through the heater core, than to have coolant stagnating in it.
