I just installed a new heater core, along with new hoses. When I was putting them on I wasn't thinking about which way they should be routed, or if it mattered. I thought that the pressure in the system would be enough to push the fluid through the hoses, but I guess not. I only get cold air in the car, even when the car is fully warmed up. I guess my question is; did I cut the hoses too long, too short, or just route them the wrong way? Or maybe the parts store gave me ****ty quality heater hose? There is pretty much two kinks in both of them, at the point where they turn to be pushed into the inlet's/outlets. I know it's still enough room for liquid to get through, but obviously ultimately it's not enough room cause I have no heat. Thanks.
