Heater Core Issue?

[L-Beez]

Hey Guys,

I believe im having a Heater Core Issue, when the heater is not on i have, (what i believe), to be antifreeze vapor coming out of my vents. Jsut want to confirm my suspicion on this matter. Also my 98' has a A/C system and was wondering if replacing my heater core i would need to drain the A/C system prior to replacing the heater core.

Any suggestions are welcome!

Thanks,

Yep, that is indeed a heater core issue you're having.

@MountaineerTom did a great write-up on how to replace it here:
Another heater core replacement (and A/C Evap core)

No problem at al! Crappy job, but it's better than having your heater core explode on your feet while driving and getting burned with hot coolant... happened to me!
