Intercoolers need to run as cool as possible. The main cooling system generally needs to run between 180f-230f depending on the car. That's why you have a thermostat.

You wouldn't cool the intake air very much if any by using your coolant system. Especially since most modern cars run coolant temps well over 200f.
