Engine Compartment Heat
 

I have read most of the posts on how to control the bleed thru heat coming from the headers and into the cabin. I can't remember which heater hose was recommended I connect a valve to (to regulate the water going to the heater core). Can I connect a valve to both hoses (bottom and top)? If I do this, does water still flow through the engine to cool it?

The engine will cool the same with the heater hoses shut off. You can stop the flow by putting a valve in the pressure line, the one from the intake manifold. Some will say to put a valve in each hose, I only have it in the one and it works good.

Can you tell us what the name of the manufacturer of the valve in the picture is, what it cost and where you bought it?
thx.

I got it from Napa for around $30 but I don't remember the part #.
