Coolant under driverside floormat

[zman]

i have a 95 civic w/b16 swapped in about a week ago. There is a HUGE puddle of coolant under the driverside floormat. Also coolant is leaking from under the engine bay, by where the heater hose from the thermostat goes into the firewall (to the heater core i think). There is no coolant anywhere else in the car other than the under the driverside floormat. I just replaced the thermoswitch today but there is not coolant leaking from there.

Heater core?

I'd say make sure the clamps on your hoses to the heater core are tight on the hoses. If the factory clamps aren't doing the trick, stop by your local auto store for some worm-gear clamps and that should solve the problem if it's just the hose connection.

If that doesn't solve it, might wanna pull the dash and make sure the heater core isn't cracked and leaking.
