well, here we go again! the cars been parked for 3 years and i have recently been starting it up. i repaired a coolant leak around the water neck and then started it up for a while. turn it off and at the end of the night decide to quit on it and i hear something dripping. look under the car and it is coming from the passenger side seat bolt hole. confused i look under the carpet and it is antifreeze that is about three inches deep!! i know it is coming from my heater core. i am going to check the hose connections first and if they are good then i am going to replace the heater core. any tips on changing the core without tearing the whole lower dash out of the car???
