A couple of weeks ago I asked for help = in solving my van's leaky rear heater, and many of you were kind enough to = send suggestions. Thank you.

Now the saga has taken a new = turn. The core was not leaking. Neither were the connections of the hoses to the heater. The leak is where the plastic valve connects to the = plastic housing at the side of the core. The leak develops when the water = is hot and a slight side to side pressure is applied to the connection by = flexing the cutoff valve to each side.

Since only two bolts are used to secure = the two plastic fittings together, there is no way to tighten the connection at = the edges where water is leaking.

Does anyone have any idea for solving = this problem? Any help would be appreciated. Right now I have the = hoses clamped off.
