The return hose that carries water from the engine back in to the radiator keeps coming off. At first, I thought it was loose or bad hose clamps. I replaced the hose clamps on both sides, and have tightened them as best I could. This did not help. Both sides of the hose have popped off on separate occasions. When the hose is connected, I do not have any overheating problems. Also, the thermostat has been removed, as it was apparently causing an earlier problem. We opted, due to time constraints at the time, to not put a new one in.
We also recently flushed the system, though as I mentioned earlier, the hose clamps are not the problem, nor have I overtightened them.
I imagine this is something to do with high pressure, but I cannot imagine what could be causing it.
The car, by the way, is a 1986 Mustang
