Cabin Temp Tip

Why would I? Good question. I just thought with a shut off valve the engine would run slightly hotter because the coolant really isnt moving through the hoses like it would if it was looped. Gonna run out and get a valve at Auto Zone. And 9 bucks is a deal. Thanks for the timely post 63valiant. Its gotten very hot in Jersey the past 2 weeks. Im sure this thread has gotten alot of views! Update-Napa up the street has one. No more cabin heat after today.. Nothing religious. Thanks again for bringing the topic up.
