A while ago I changed all the possible hoses under the hood including the cooland/heater and radiator hoses.

After a full warm-up I start driving a smell of antifreeze comes in not so strong, seems like it dissapears for a while but it comes back again after few minutes of driving,
I'm pretty sure that there in is no leak in hoses and the coolant level doesn't change,

It's totaly freaking me out, could it be I have a blown coolant seal, or what the heck it is?
If it's a coolant seal a rebuild is on my way right?, how soon?

Is there a way to find out/test if is a coolant seal?

Any input appreciated,
Thanks.

 

Heater core.

It will also inexplicable fog up your windows such that you have to wipe them down to defog them.

Check for wetness in the passenger footwell and up in the HVAC box up under the dash.

 

bond007 is probably right. If it is a coolant seal you would get a sweet smell from the exhaust.

 

Hmmm, I'd have to check the carpet in pass. side, and you are right about the fog crap, pretty anoying to...

About the smell from the exhaust, (I read before about that) , I try to smell it few times but it doesn't seem to smell at all like antifreeze.

How do I check the heater box for leaks ?

 

Go rent a coolant system tester from Autozone or have a coolant pressure test done...that along with a compression test and smog sniffer to coolant overflow are the definitive tests for a blown engine. If you smell coolant INSIDE the car, it is most likely the heater core (a PITA to RnR in just about any car).

 

Yea I guess I'm gonna do the coolant pressure test but what's the smog sniffer...?
