I noticed a water leak and when I pulled the thermostat housing I noticed a leak from the inside up and round the top of the manifold, where the thermostat bolts to. What to do? Is there an aftermarket manifold available? I am not to hyped on the plastic manifold, it was already replaced by the dealer once, under the recall. This sucks. I am going to JB weld and seal it with silicone for now...but this is only a temp fix.
