Hello Hun'
First in the fire wall you will see 2 heater hoses they have to be dis.

then under the dash if thire is air condn tubes you must remove them .

Then you will see a black heater box take all the screws out.


And then thire two clamps holding the heater core in . And to install
Go . the way you took it out.

A good 6 hours to in stall and remove .

Good luck to u hun and if you need more help just let me know .
