remove the rh inner fender so you can remove the nuts that attach the inner heater box to the firewall. Unhook the coolant hoses and the cables used to change temp and air direction. It should pull away from the firewall and then you will have access to ther heater core pretty simple if you take your timecheron20 said:Hi Guys,
