I replaced my heater core in my '97 a few months ago. Be sure to allow yourself plenty of time. There are a lot of little screws in hard to reach or out of sight places. It took my dad and I one whole day just to dissasemble the dash enough to get to the box. It took another day to change the core and connect it to new heater hoses and to get the dash halfway assembled. Then, another half day to put the rest of the dash and trim pieces back together.

This was taking our time and having a couple breaks here and there. Dont forget the defrost vent tubes. I forgot two on the driver's side and had to take it apart again. I have a handfull of screws left over...but the dash is solid and doesnt squeak...so that's good.

And BE CAREFUL around thoes airbags!
