My 2011 plus 4 has a very good heater but I can't get it to blow cool air.

When the heater switch is off and I turn the air on it comes out really hot.
What is the best way to bypass the water from the water pump straight back to the block bypassing the heater?

I noticed when they toured NZ that some v8 engined Morgan's had a fancy valve that did this.
As hot weather approaches in NZ I have a need for cool air around my legs. Thanks guys.
