Heater core water cutoff...

I installed a water cutoff to help make the a/c more efficient. My question is will this affect the coolant going to the rear of the block? You know....like the wrong ( short ) thermostat directing water in the wrong direction or something like that??
Thx Schlepprock

I shouldn't hurt a thing. The heater core is kinda like a coolant bypass. Only some flow is directed thru it.

A lot of guys have done it that way with no apparent problems. I did the Autozone part # 74809 way so the coolant still flows just to be sure.

One good thing about doing your way is that silt won't get trapped in the hose before the valve and when opened would get possibly trapped in the heater core.
