5k coolant leak

[eyvind.spangen@c2i.net (Eyvind Spangen)]

When I fill coolant on my '87 5k, it will leak slowly out, and drip
from somewhere in the middle/front of the engine. It was really bad
when first starting it (it sat for 6 months), but before I started it,
it didn't leak. Now, the leak is smaller, but I still have to bring a
1 gallon can of coolant, and after driving for a while, I have to top
it up. (red light in the autocheck) Could it be a dried out gasket
that will re-seal when the car is used for some days, or do I have to
change the water pump?
