I have one seriously stupid problem that i need help with. Yesterday i replaced the heater core in my 95 blazer. The core was blocked off when i purchased the truck. I am now having a hard time finding the coolant return hose. The big hose with the flow valve is still in the truck but i have no clue where the other hose would be or where to route a new one if i had it. Anybody care to pop their hood and give me a clue? Thanks
