where all is the cooland routed in the cab for like the heater core. i just thought of something today. right on the tranny hump up there under the dash on the carpet there has been a stain i have cleaned a fiew times. it was like a rust collor not too noticeable on graphite interior. i never realy thought about it or what it could be but there is deffinatly a slow leak of some sort. does any body know what is around that area?

 

Maybe sweat from A/C had a similar problem with my 2000 silvy.

 

With that color, you may have a pinhole leak. If under warrenty get it repaired!

 

like i said it is like a rust color that is why i think it is possibly coolant. waranty is long gone. i guess i will just have to tare it apart next time i am home.

so z were exactly was the prob you had mine is a 2000 an like i said it is on the tranny hump. but i dont get why it is the rust looking color.

 

I would guess a heater core leak, mine did with 5k on it, luckily under warranty. You should be able to smell the coolant, if it is coolant, and the leak I had caused the windows to fog up horribly. I hope that is not what your problem is .

 

The rust color is because of the 150k antifreeze you most likely have in your system. It is a reddish/pink color. If your antifreeze has been changed to a green, regular 50k antifreeze than you most likely have problems with rust build up and you need a flush. I would bet on the first scenario though. I have been smelling antifreeze in my truck for a month or so now, but my coolant level has never dropped. I figured I had a pinhole but still haven't checked. Come to think about it, I haven't smelled it an a week or two.

 

had the problem with condensation dripping from under my dash and kick panel. Never really new what it was but it cost me to rip out the carpet and pad. Scrub everything down because mildew was growing under neath the carpet. Here in oklahoma during the summer I use the AC alot. since it gets to 105. It was the perfect hidden spot for mildwew and all that other nasty stuff. Have you ever driven a truck with dumps without carpet. Damn its loud.

 

that is funny you say that. i had my pass seat out and it was quite a bit louder so i could imagine how loud it would be with out the carpet.

 

yeah I had 2 1chambers with 6 inch pipes dumped right behind the cab. talk about to loud. Interior vibrated so bad I couldnt stand it.
