Coolant disappearing and going nowhere
I've owned a couple 3800'*, so nothing strikes terror into my heart like the low coolant light. That quickly flashed on during a tight turn, so I pulled into a gas station and killed the engine. There was a little coolant in the tank, the radiator cap was cool (I didn't open it), and the upper hose was empty -- but the engine temperature was normal, and the heat was working normally.
Now, I don't have an oil milkshake nor condensation on my oil cap (LIM'* probably good), I have no white steam or smoke coming out of the tailpipe (UIM probably good), and my parking space is always bone dry (no leak) -- so where is that coolant going?
The last owner said he replaced the LIM gaskets, and there'* no loss of power like the Bonneville had when its UIM was starting to let go. At this point, I'm wondering if people are siphoning it out in the middle of the night.
