I am having an issue locating all of the fasteners to remove the core. I think all ate out but I don’t want to pull too hard and break something. Does anyone know of a video or diagram?
I have the Haynes manual but it isn’t very helpful. My son said “it basically says - step 1...just do it”.

You are correct. It basically does just say to remove the heater core. However, one thing he is over looking is it says to remove the HVAC housing and then remove the core.

I attached the process on how to remove the assembly and once that is out remove the heater core is much easier.

Let us know if you have more questions and we can figure out what to do next. Thanks
