[TalonRacing07]

ok guys, there was coolant leaking from under my dash,a nd windows fogged up, so i pulled dash, and took heater core out, got a new one from a store put that in and start car. leaking again. even with heat off it leaking out bad. so i pulled it again, somebody told me to check if leaking by running under faucet, theres no water leaking from either of them. whats going on here, any help would be great

Hoses instead of core.

so the main 2 hoses going to the firwall could be leaking down into the firewall? i was thinking about that but didn't think it would leak it all the way down into the firewall

Do yourself a favor - Change every Coolant Hose on the car...
