I replaced the water pump this past weekend ($200+) because I was adding fluid every other day...had it tested and it was "seeping". I've driven it for 3 days now and this morning it is dripping...from the firewall. More than likely it's the heater core, but I'm hoping it's just one of the hoses. There's only 70k miles on it! Anyway, I'm venting and want to know if anyone else has change their heater core? Is it hard to do?
