I bought my '02 Bonneville a month or so ago with just over 60k miles on it. I know the LIM gaskets are a big issue on these cars but mine seems fine. The oil looks like honey. One of the first things I did was have the DexCool flushed and refilled and ever since it has leaked. It doesn't seem to be leaking from the LIM gasket, though. It seems to leak from the coolant elbow that runs from the water pump housing to the LIM. It might be cracked but I actually think it is the seal between the elbow and the LIM that is bad. How does the elbow seal to the LIM? I assume I have to remove the water pump to to remove the elbow? Anybody else have this problem? It doesn't seem to leak when the engine is warm, only when it is cold.
