[:@]just complaining about my z28 damn heater core is going turn on the heat and it leaks antifreeze from the fire wall. i'm sure its just the tubing for it but still its a quite hard to squeeze my hands in there to get to it. and now the serpintine is about ready to go on me just small stuff but stuff that agrivates the best of us at times. well anyone knows any secrets about the heater core please inform me thanks.
