How to replace a heater core on a 83 mercury marquis? I looked at a manual and it did not give much info but had 3 different ways. One was from under the hood removing the a\c, the other was removing the dash, and the other didn't apply it was for a car without a/c. Just wondering what I have to do. Either go through the dash or under the hood?
