I Got me an 02 blazer zr2. i got it about two months ago i started smelling radiator fluid didnt really think anything would be wrong. But all of a sudden ive had a mist comming through my vents and fogging up my windows. Everything i read leads to a bad heater core the only thing i dont have any moisture build up on the passenger side floor anyone know what could be wrong? Could it just be cloged?

 

Yep heater core has a leak

 

so if i wanna bypass it for now you know what the diamater of the radiator hose

 

2 different sizes, 3/4, 5/8

 

You know you will have no heat, right

 

thanx and yeah i know im in south east CO i wont need it until i go back to wi and thats were i left all my tools that i can work on it here i shouldnt have to worry about it to much

 

Help has an adapter 5/8 and 3/4 most parts stores sell just unhook hoses from heater core on firewall connect both ends of hoses to the adapter.
Harbour freight sells a defroster heater that plugs in cigarette lighter, I bought one and it seems to put out some heat i havent tried it much as I'm in Florida but should work for defrosting.

 

Why did you buy a defroster heater when you live in FL LOL

 

I tried it out this morning it was 51 degrees and its not like a real heater puts out very little and yes it does get a little cold like 32 or so here but not like colorado minus 30 with a 20 mph wind. I do miss the cold sometimes but not the cold feet!

 

I will gladly trade places with you up here in MPLS.
