Im thinking that I know the answer to this but just thought I would ask before I take apart the dash and replace the heater core. The smell is only when the fan is on high (4) and I dont see a leak on the floor of the passenger. To those who replaced thier heater core how long did it take? thanks

BTW
This has been this way since I got the car.. about 2 years Im just getting sick of it.

 

You may not have to replace the core. If the leak is small enough you may be able to fix it with a "stop leak" product (such as Barr's Stop Leak) from your local parts store. It may not work, but the way I see it it is worth the $5 to try. This stuff has worked for various projects of mine in the past.

 

My car also just lost cabin heat. I bet the heater core got clogged up just like my old radiator.

 

You guys have heat?

 

and lots of it!

P.S. Replace the heater core if it is bad, I would not use a "fix a flat" cooling system repair in a bottle.

 

Yes I do have heat.... but I only get the smell from the highest number. Its not really strong but the smell is there none the less.

Also here is another item.. When I have the turn **** set to cold and pulling in air from the outside lets say in the summer the air really isnt very fresh meaning. It smells like exuast (I dont have a exaust leak I know that much) It gets bad when I get "on it" then for a while it smells.

Has anyone used stop leak? I have a brand new rad. and dont really want to gum it up. Like I said I have no experience with that stuff.

thanks for the replies guys

 

have you had a shop pressure test your cooling system? This will show if you have a leak. You may have to have your temperature control **** to hot and leave the cooling system pressurized for a while. If the pressure drops you have a leak some where. Then start the car, turn the heater on full with the blower runnig full, get up under your dash and poke around to see if you have a hot wet spot. Also coolant is a little greasy, so if you find a spot on the carpet that fells slick, smell your fingers and if its sweet, it coolant.

Good Luck

 

OT: Is it me, or is 4 fun's blue font in his sig literally painful to your eyes???

 

If I change the font color will it fix my problem?
