If it is not leaking externally then it is leaking internally. The intake manifold gaskets are known to leak coolant into the engine on that vehicle. Have a trusted mechanic diagnose the problem soon because coolant mixing with engine (even in small amounts) oil will cause big trouble down the road.
You have a leaking heater core. You might smell antifreeze if you turn on the defroster.

Sounds like heater core is leaking and what you are seeing is antifreeze
Your heater core could be leaking, but that would smell like antifreeze. You could have had a windshield replaced by a moron, or you could have had body panels replaced by the same moron. Unfortunately you need to stick your nose in there and see if it smells like antifreeze, coz that's bad news Phil
Heater core has failed.
i found out its the heater coil needs to be replaced..thank you for your time
Check for a sickly sweet smell. The heater core is probably leaking coolant into the floor. The core is not repairable but can be replaced.
