Question about Honda Civic

2 Answers

Exhaust fumes I noticed the smell of exhaust fumes in the cabin of my 2000 Honda Civic any time the vents were set to pull air from outside the cabin. This is only when the car is sitting sit in the driveway or at a stop sign idling(cold or hot). Switching the vents to recirculate will prevent the fumes. I have asked my mechanic to look at this a couple of times, and he could not find the cause. I'm looking for suggestions on what to try next to diagnose the problem.

Manifold or down pipe on the exhaust is leaking,, replace the gaskets on both check for cracks in the manifold and if found replace the manifold or you might be able to have it repaired, down pipe has a gasket of sorts, these can rust away over time and lead to leaking. down pipe its self can suffer from pitting as well this is due to the heat and cooling down. parking on wet grass can also make the exhaust crack over time.

Look for a bad gasket where the pipe connects to the manifold. Could just be loose bolts or a bad gasket.

I smell exhaust fumes in the cabin. What could be causing this?


The most common cause is an exhaust leak in the engine compartment near the engine. The exhaust fumes are pulled into the passenger compartment thru the heater vents. Switching to Rec might cut off the intake of air from outside.

I have a 2010 Chevy Equinox. The air vents in the vehicle all work except for the drivers side right vent ( to the left of the radio and to the right of the driver ). All vents were working but it seems as...


The exhaust inside the car would suggest the vents in question have fallen apart somewhere in the dash between the engine compartment and the interior allowing fumes to enter the cabin. Get that checked at a garage right away. Very dangerous to breath exhaust fumes.

Smelling exhaust while in traffic


Are you sure is exhaust emission or a fuel smell? If is others Exhaust emission,and is coming in the cabin possible you might have ventilators not working properly,or the doors under the dashboard are kept slight open allowing the outside smell or getting inside the cabin. On the dashboard there is a circulation air button,press it to work. What that button does? Is blocking the outside air coming in and the air you are using iis the inside cabin air only. Use that button for a day and see whether you have any improvement. If so you have to go back to the dealer and explain. Surely they will help you.

Exhaust smell coming in from vent


In most cases fumes coming into the cabin thru the vents is from a leak near the engine. If the exhaust is leaking around the engine it should be fairly loud.

Gas Fumes in Air Vents


This could be as simple as a hole in the exhaust under the cabin area. I would also check that all cylinders are firing properly. They can do a fuel pressure test to make sure there is nothing wrong in the line as well.

Fumes in 2000 Toyota Sienna


On the dash there is a switch/lever that allows you to select fresh outside air or recirculate the air in the cab. Any smell may be coming in the freash air position which would allow smelly air from the engine to come into the car. Check for broken flexible exhaust piece or leaking gaskets around the cat converter to start with or a hole in the exhaust pipe inself

Cabin smells when heat or defroster is on


What your smelling is most likely coolant (antifreeze). You may have a heater core leak. If you dont smell the same smell after running the A/C or just vented cool air from outside for a few minutes then that is your problem.

1997 Honda Civic EX: Exhaust fumes coming inside


hi, this might help you:

at first make sure your air system is set to take the inside air of the car. this is the button with the car on it with above this little car a circular arrow like as if air circulates only within the car, or like the air from the outside wont circulate inside the car.

if not:

if possible get a expert to do a check up of the body/chassis, it might be in a condition where rust has made wholes in eg a part under your seat.

it might also be that something is wrong with the ventilation part of your honda, like 'tubes' are leaking within the engine bay or??? something like that.

ive had a honda, not this problem, but i think it'll be something with the isolation and or the plates between the chassis 'bars'....

hope you'll find a solution soon.

2000 Civic stolen, air controls taken, then clutch fell off


Coincidence... in my opinion.

1. In your long drive, you may have set the a/c on "Max" or "recirculate" ... and set the fan on low. This can cause "freezing" the core inside the vehicle; this will create a lot of pressure in the compressor and the clutch will slip.
The "freeze" will cause the air to feel warmer; because the refrigerant is not circulating correctly.

2. Also, if there was oil or some other lubricant on the clutch, the clutch would slip, heat-up and fall apart.

3. The "fixed" a/c controls may have left the "vent" (non-circulating) control disconnected so that the inside core is unable to receive any "outside" warm air to keep the core from freezing... (possible)

Hope this helps ... comments anyone??
