Thinking back a little to before I replaced mine, I had a slight coolant smell every now and then and I did not see any level change in the tank. It turned out I had a very small shaft seal leak that got worse over time .

If you see any dried coolant, clean it off and check again in a few days assuming you have driven the car a bit

Thanks, I'll check this. What was the repair solution?

A reasonably easy DIY

I replaced my WP (Pierburg), thermostat and 3 gal of concentrated Porsche coolant was ~ $350

When the engine was replaced, did they reuse the WP? It is not that uncommon for that to happen

Conventional wisdom is the WP should be changed @ ~ 70k anyway
