Hot air coming from the bottom of my car

[Somebody]

not talking about it coming from the back where the exhaust it... eg... when i pump air into the tyres, i can feel hot air exiting from the bottom. when i open my driver side door and exit, i can feel hot air at my ankle area. even the floor of the car boot is a little hot.

 

any ideas?

That is your aircon fan and radiator fan blowing lah.

 

Its normal lah...dun worry about it.

[Kyojin]

oh shiiiiiiiit... your engine not pumping out enough cold air... think siao liao. your car need to scrap already.

 

of course you'll feel the heat coming from under your car. even without your air con or radiator fan on, the heat from the engine will be conducted to the air underneath the car. and because of density/pressure differences, the hot air will want to flow out from under the car.

hahah! don't make fun of me la!

 

i'm asking coz i don't remember facing such situation with my old car... only feel the hot air from the exhaust and not from the bottom and coming out of the sides of the car...

I think alot going to bomb this thread

 

Anyway, when you leave your aircon running, the aircon compressor fan will run to extract the heat. As it's an on off thing, therefore sometimes you encounter the hot air and sometimes not.

i'm asking coz i as scared that there's some exhaust leak or something... don't wanna kena CO poisoning...

Chances of exhaust leak is small, the air con external air inlet is located at the front, so the chances of CO poisoning is low.

 

Just thinking this thread is quite similar to the other one, hand brake how many clicks lol

 

Like your attitude! Just laugh it off

lol. Exhaust is designed to leak at the back. If it leaks slightly at the front, okay lah!

 

I guess the issue is Singapore is hot these days with very limited rain. Why don't check if you feel the "hot" in a rainy day?

any abnormal noise from exhaust system? might be a leakage along the exhaust system from the header down...

exhaust leak liao.. [laugh]

exhaust leak liao.. [laugh]

 

How old is the car? The only leak that can happen will be at joint area unless it's a very old car. And the leak must be damn big to experience the hot air.

If exchaust leak in the front or in between, your car will start to sound like a F1 already [:p]

That is even good leh. It will be a Ferrari. Just change the batches and put some Ferrari stickers!

Looks like TS can feel the heat only and not the sound

if leak a bit wont sound like F1, only sound like been when you move off.

 

the leak should be at the neck area

Some new cars ecu will have the radiator fan turned on for a while after the car is shutdown to help lower the engine temp and reduce heatsoak. You probably feeling the draft of the rad fans
