Default Heater Core Leak, How Hard To Change? 2000 Mustang GT

So I'm getting onto the highway by ramp and start hitting throttle early (due to new suspension) with the heat on my feet, and my right foot get hit with some coolant. Check it out and my heater core is leaking. Can find at auto store for $45 but how hard is it to replace? Looks like its in the car behind the dash... Anyone can help with this would be awesome.

It's not hard but it's a b1tch. I dont know about the 00 mustangs but fox body some you have to take the dash out and some you just open the glove box and get it out. First, take the glove box and see if you are able to take it out, if not, spend about 4-7 hours to replace.

You have to pull the entire dash, and it sucks. There's a lot more involved than I thought there would be, especially with the airbags, and all the radio and heater controls. It was a nightmare, but labor costs are like $700 for a shop to replace it, so I did it myself.

Here's a tutorial:

yeah, it's almost identical. Just the radio plugs are a bit different, but I'm sure you can figure that part out.......

Alright, may get into that next week. Anyone ever just bypass it temporary? Just connect the two hoses going into the firewall together.
