THERMOSTAT HOUSING LEAKING

1999 Lincoln Town Car

Engine Cooling problem
1999 Lincoln Town Car V8 Automatic 120, 00 miles

The thermostat housing is leaking coolant; I have already replaced the O-ring, but the housing is still leaking. The only leak seams to be where the housing comes together (no leaks around hoses or bolts, etc). Any help would be greatly appreciated!

I just got a 1999 Lincoln Town car that had a leak so I replaced the seal and it still leaked. I cleaned the housing with a solvent and ran the motor until it got hot. Parked it and watched the housing and found that it was seeping out of a crack in the housing. These manifolds of plastic crack a lot. I put Bondo on the crack and it lasted 3, ooo miles. Then I put super glue which sealed it. Now a little leak which means a new manifold.
