I was wondering if any one has ever changed their heater core on a 99 excab silverado. Mine is leaking and was wondering what I was in for before I dig into the dash.

99 excab, Nelson Tune, k&n FIPKII, pacesetter long tubes, No Cats, Dual Magnaflows with turndowns,
1/4: 15.66@88.1 Before Nelson, headers, and de-cating
Also 69 camaro SS 350 4speed, 13.81@103.6, Ls1 swap planned
if i'm not mistaken, you have to go all the way down to the bare firewall to get the heater cores out of the new body style trucks. I haven't gotten the privilage of doing one yet, but it's inevitable. Good luck and let us know how it goes.
sorry i aint much help, sure someone else will chime in soon!!
My heater is know leak free. After about 6hours of going into uncharted terain I got everything back togeather and no leak as of yet.
