If my heater core was leaking,why wouldnt i have water on my cabin floorboard? how do i tell if heater core is leaking?

Scott, do you see external leaks on the ground? Where? if so, that's not a leaky core, but something else,
When you turn on your defrosters the anti freeze may vaporize and cause a film to form on the inside of the windshield. Take a cloth and wipe the inside of the windshield to see if it smudges. If it does, it IS leaky core inside the box. If not, it still could be a leaky core, but it is not enough to get blown around yet. The heater core box is acting like a bucket. Pull the carpet back by the passenger's feet at the firewall. look to see if it is soaked under the carpet. Pull back the Driver's carpet. Antifreeze travels. Do you see external leaks on the ground? Where? if so, that's not a leaky core, but something else, Lastly, does it smell like antifreeze inside the car? Check all this out and let us know your outcome, Scott. (A heater core in a modern care is not for the faint of heart or limited skill levels.)

Overheating and antifreeze smell

If you are smelling antifreeze inside the truck, it could be the heater core. Feel the carpet on the passenger side. If its wet its the heater core. A blown hose under the hood is easy to spot. The only other things it could be is a water pump, thermosat, or radiator. If the water pump is bad it will leak through the weep hole on the underside of it.
If no leaks anywhere, change the thermostat.

Water leaking onto passenger side floorboard,soaking the carpet

Your heater core has developed a leak - the wetness on the passenger side carpet is engine coolant
from a heater core leak, or a leak in one of the two hoses connected to the back of the heater core.
Your strategy: disassemble dash down to heater core, determine whether you'll need a new heater
core or new hose (or new hose clamp), then replace the offending part.

I have an 1999 chrysler 300m an it has an overheating problem. There is also water all over the driver side floor (front n back) it is soaked. It takes about 25mins b4 it starts smoking. Can som1 plz help...

Typically if your leaking coolant inside the car, it indicates your heater core is split and leaking. Replacing the heater core is quite the job. It requires removal of the dash board and heater box. i replaced one in a 97 Cirrus at work last week and it was a 6 hour job. If your not mechanically inclined i would definitley recomend phoneing around for quotes to local auto repair shops and getting it done profesionally.

Smell of antifreeze in the car why is that?

If it's not leaking externally I would check the heater core. Feel the carpet under the passenger's side of the dash. Wet carpet = heater core.

Water is dripping from outer heater unit and soaking passanger side of front carpet.

There are two causes of fluid dripping from the heater core/ac evaporator housing. First, if it is running inside the vehicle and getting the carpet wet as described then it is most likely a bad heater core leaking antifreeze into the cab. Secondly, if it is dripping outside only when the a/c or defroster is running then it is the normal expulsion of condensation and is harmless.

I can smell coolant when heater is on and coolant light is on

Sounds like the heater core is leaking. Fill up the coolant and look under the carpet on the passenger side and see if there is not coolant there. IF it is a really minor leak you may be able to use a radiator fix, but do not buy something cheap and follow the directions. If one application does not seal it up, replace the heater core. It is not worth overheating the motor to try more of the sealer; it can clog the coolant passageways in the motor.

Hope this helps

Bad smell in car and is using a lot of anti freeze

Floor and carpet wet

absolutely can be the windshield. With an assistant sitting inside the car to examine the windshield edges as you slowly apply a slow soft stream of water on trhe windshield, going slowly starting at the top. If in the end , no leak is found, examine inner firewall going up under dash for water drippage. No guarrantee the leak is the windshield. Could be a side door or window leaking. Imagine if your carpet was soaked with engine coolant. Could be the heater core leaking into the inside of the car.
