When i initially asked the question i didn't see the part about the damp floor. sounds like the heater core is indeed leaking. someone may suggest using stopleak or something along that lines. i wouldn't recommend it as it will block passages in the motor where you need water to flow for proper cooling. basically you need to have the heater core replaced. if the vehicle is old and dying stopleak may be a cheaper alternative tho.

2001 Honda civic overheating, losing coolant, damp passenger floorboard


Damp passenger floor sounds like a heater core. What a pain in the a__. Most probably the dash has to come out to replace. That is the only thing I know of that circulates engine coolant into the passenger compartment.
If you confirm this and want to fix it on the cheap, you can put a crossover hose in the engine compartment and bypass the heater core entirely. This is a $5 fix that works perfectly, mechanically speaking. Unfortunately, you will have no heat. Of course, you may decide that is a better option once you hear a quote on getting the heater core replaced.
Oh yeah, get a new mechanic.

I have a 1999 expedition and when i turn on the heat it blows smoak/fog and it smells like burnt coolant.. what do you think is wrong


Sounds like you will need to replace the heater core as it's leaking antifreeze inside the vehicle. Check the floor on the passenger side for dampness.

My van does not have heat. The floor on the passenger side is damp along the trim. I think its the heater core. How can I be sure?


The easy way to verify a bad heater core is by using the heater or defroster if the vehicle has antifreeze in it. If it only has water in it when the defrosters are on you will get a steam build up on the window like its getting fogged up. If antifreeze is in the system when the defroster or heater is on the air coming out will have an odor that smells sweet.

Water standing on passagers side, drove about 50 miles low coolant light came on running fine and heater seems to be working


The problem is that the heater core has started to leak. The 'water' on the passenger side floor is actually coolant that is leaking from the heater core (hence the low coolant light).

I am loosing antifreeze collant about a cup a day. I am brown gook in my radiator and the reservor. I smell antifreeze and for a couple of days my windsheild would fog up. I have not seen any antifreeze...


Usually when you have these symptoms, the first thing you should look for is coolant in the passenger side floorboard. Just run your hands over the carpet and feel for dampness. if you have floor mats, ne sure to check under the floor mat. If it is damp you are most likely going to have a leaking heater core or heater core hose

Heater immediately fogs all windows and there is a sweet odor in the cab of 2003 Buick Rendezvous, defroster works fine, but will not clear the windows after heat is put on


Sounds like a possible heater core failure(hole in it) the smell indicates to me the coolant(anti-freeze) is leaking into the passenger compartment.
Check the carpet in front of the front passenger seat for moisture, this would confirm heater core leak.
Good luck !

Water in passnegers floor New Beetle


Yes, your heater core is leaking. Dash will likely have to come off. Along with everything that is tied into the dash. Best thing to do is to take it to a repair shop. But before you go off to the shop.. take up the carpet coming from your passenger side front..just pull it back. Far as it will go. Then get the car hot. Run your heater full blast. Also place a white rag at the vent under the passenger seat. It maybe leaking into the ducking and flowing out through there. GOOD LUCK!
Here is a link to how to change the heater core yourself...IF you have the proper tools. As it does require you to evacuate the freon...evacuating into the air is ILLEGAL and there is a very very hefty fine for being caught. $10,000 fine I think
