I know I have it, the flow valve. Just wondering if I have to use it. Or what will happen if I don't.

I asked this same question when I asked for help doing first coolant flush, Forum members and my mechanic friend said to use it as it regulates heater flow, block flow from pump. So i did.

Well bad news. Seems like they don't have all the parts to make up for those hose size differences for the ends. And, I just searched for the heater hoses. Everyone has only one them. The other is on "national backorder" Hopefully the dealer can help tomorrow on getting the other hose.
