Easy. It leaks out of something, runs down something, and then finally drips down to the floor when it can't run anymore.how is the coolant under the block
This^How are we supposed to know? It's not leaking on our engine. Take a look at places where coolant lines run. Check for cracks, etc.
You should seriously think about writing DIY's but in all seriousness he is correct. My d series had the same problem. But you will have to find the leak because we can't see your engine and walk around ourselves to find itOhhh, it must be the hose under the thing next to the other thing.
